pollenia rudis development

The flies tend to frequent dry areas because of their aristae antennae. [9][12][13] The change of genus to Pollenia (suggested by the pollen of flowers) occurred for Muscids having, among other features, the thorax covered with "down-like clothing". Pg.214. They are brownish-gray with numerous short yellow hairs on the thorax, a … Jacobs, Steven B. Some specimens have black basicosta. Once the fly has died, the wasp will feed the fly to their young. Pollenia rudis, the common cluster fly, is a species of fly in the family Calliphoridae.Pollenia rudis is also known as the attic fly, the loft fly, pollenie du lombric, and the buckwheat fly.During the autumn and winter months, Pollenia rudis can be found overwintering inside of attics or lofts. Fungus Gnat. Page designed through the cooperative efforts of interagency ITIS Teams. Houskova L. Rozkosny R. “Diptera as Bioregulators of Earthworms in Southern Moravia Czechoslovakia. The Face Fly (Musca autumalis) which is similar in appearance to the House fly will also overwinter within homes. [7] Piles of dead flies left in the walls can sometimes lead to secondary infestations of carpet or larder beetles and rodents. [14] The adult Pollenia rudis looks like most of the other Pollenia species such as pallida, and dasylpoda. [10][11] During the summer, P. rudis can be found in fields and open areas. The typical grass fly Pollenia rudis is about 7 mm long and can be recognised by distinct lines or stripes behind the head, short golden-coloured hairs on the thorax, and irregular light and dark gray areas on the abdomen.Cluster flies are typically slow-moving. P. rudis can be found wherever their host earthworm, the Allolobophora genera (also known by the genus name: Aporrectodea), occurs. The cluster fly, Pollenia dasypoda Portochisky, is known as endo-parasitoid on the earthworms, where all the three instar larvae complete their development inside the same parasitized individual of the earthworm. They are nonmetallic gray, lack stripes on the thorax (segments with the wings and legs attached), and have yellow or golden hairs on the back, behind the head, and around the base of the wings. Parasitism by Pollenia rudis (Fabr.) Thomson AJ (1973) The biology of Pollenia rudis, the cluster fly (Diptera: Calliphoridae). They can also be found in old bird nests, under the bark of trees, or in homes. There are also other generalist predators of this fly, such as ants, birds, and certain plants. Pollenia rudis is most commonly known for being a household nuisance. “A Summary of Published information on the cluster fly Pollenia rudis (Fabricus) (Diptera: Calliphoridae).” Phytoprotection. During the autumn and winter months, Pollenia rudis can be found overwintering inside of attics or lofts. Adult flies emerge a few days later. After some time with this disease, a P. rudis adult will lose the ability to fly. Development time from egg to adult varies from 27-39 days. However, cluster flies make their debut in the autumn when they fly to the sunny sides of homes in search of protected over-wintering sites and may be found flying about inside, often in great numbers, throughout the winter. This species is widely distributed throughout the United States, Canada, and Europe and is considered a pest species in structures. By randomly moving through these pores, P. rudis larvae find their host worms. Accession Number : AD0768630 Title : The Egg and Chorion of 'Pollenia rudis' (Fabricius) (Diptera: Calliphoridae), Corporate Author : MACDONALD COLL STE ANNE DE BELLEVUE DEPT OF ENTOMOLOGY Personal Author(s) : Richards,P. Due to the development of new housing in this area, this fly is rarely encountered. [3][4][8] Pollenia rudis was first documented by Johan Christian Fabricius in 1794. They are mainly found in forest or wooded areas during the cold season. It is bigger (8 to 10 mm) than the House Fly and other flies encountered indoors. [1], Pollenia rudis is most commonly known for being a household nuisance. Dark grey–olive thorax clothed with crinkled golden–brown hairs. 1, pg 82-83. Vol. Pollenia rudis, the common cluster fly, is a species of fly in the family Polleniidae. During the summer, P. rudis can be found in fields and open areas. 19(5-6). There are usually about 4 generations per year. Before overwintering, cluster fly’s abdomens are full of fat globules that may be left over from its larval fat bodies. Common Name: Cluster Fly Scientific name: Pollenia rudis Size 8mm Biology: Eggs are laid in soil cracks and wall cavities these will hatch in about 3 days. Cluster Flies . Cluster Fly (Pollenia rudis) which feeds on earthworms will utilize homes to overwinter. Eggs are laid in soil cracks and wall cavities these will hatch in about 3 days. A larva is prompted to penetrate an earthworm when it senses “penetration inducing factor,” a substance that is present in the slime and coelomic fluid of an earthworm. [17], Entomophthora muscae or Entomophthora schizophorae is a fungus that commonly infects adult flies. April 26, 2018 The large sluggish flies known as cluster or “attic" flies (Pollenia rudis and relatives) often invade New Hampshire homes in fall and turn into wintertime pests. [19], There are very specific differences between the life cycle of Pollenia rudis in Europe and North America. It would be tempting to talk about cluster flies such as Pollenia rudis at this point but most in the industry know about their overwintering capabilities as adults, especially in attics. [5][9][12] This taxonomy was changed in 1830 by André Jean Baptiste Robineau-Desvoidy to Pollenia rudis. P. pallida has a broad, flattened facial keel. This fungus causes disease within the fly resulting in a swollen abdomen. larvae on earthworms in the field was found only in Allolobophora chlorotica (Sav.) 6–10mm in length. O. Thomson AJ, Davies DM (1973) The biology of, Howard, Russell "Insects and Arthropods" Diagnostic Services at Michigan State 2006, Greenberg, Bernard, and Kunich, John C. Entomology and the Law. During the autumn and winter months, Pollenia rudis can be found overwintering inside of attics or lofts. 213-222. This swollen abdomen makes the wings and legs spread apart, ultimately causing the fly to have trouble flying. [22] P. rudis is extremely troublesome to home and business owners, but does not cause any true damage to home structures, textiles, foods, or humans. The flies will inhabit the old tunnels created by past insects. Studies of large hibernating populations in 196 The first reports of cluster flies as pests in homes occurred as early as the nineteenth century, and these flies continue to cause problems today. [21], More than one larva can penetrate a single earthworm, and two or more larvae can share a penetration site. Rognes, Knut. For example, in New Zealand an entire city’s water reservoir tank was drained due to high levels of fecal coliform bacteria produced by mass amounts of cluster flies residing in the tank. [20] Usually, the pupal stage lasts from 32–45 days, but at high temperatures (e.g. Pollenia rudis Homeowners are accustomed to swatting flies in the kitchen during the summer months. The main predator of P. rudis larvae is the sphecid wasps. During the summer, on a sunny day these flies can be found without much trouble. and Eisenia rosea (Sav.). This ritual begins when the weather starts to get cold. [6] This is possible due to the hibernation behaviors of the adult cluster flies to seek shelter for overwintering. [20] In Canada, 25–30 days are required when the temperature is 23°C, and 11-14 of these days are spent in the pupal stage. Persistent use of insecticides has also been shown to reduce fly numbers if sprayed on the exterior of a home. A. The cluster fly, Pollenia dasypoda Portochisky, is known as endo-parasitoid on the earthworms, where all the three instar larvae complete their development inside the same parasitized individual of the earthworm. Eggs are laid in soil cracks and wall cavities these will hatch in about 3 days. [12] P. rudis has also been previously described under the name of Musca familiaris in 1869 by Dr. T.W. Specimens in poor condition may lack setae, causing them to resemble P. angustigena,particularly females. Usually, the first and second instars act as internal parasites while the third instar can parasitize the host and feed on the surface of the host. The life-cycle of Pollenia rudis, F., is described. The author concludes that P. rudis may hibernate as an adult, and that the eggs are then laid in … Pollenia rudis, the common cluster fly, is a species of fly in the family Calliphoridae. The literature dealing with this fly, which is scanty, is reviewed, and the life-history and habits are described from observations in captivity. The basicosta can be found in many colors ranging from yellow to light brown. Plant sap, fruit, flowers and feces are common energy pathways for P. rudis. 103-111. Cluster flies are typically slow moving and pass the winter as adults so are very common in early spring. [1] Cluster flies tend to enter homes and buildings in large masses in late summer or early autumn to seek shelter for the winter months. "Cluster Flies" Penn State Entomological Notes 2003-03, Alm, Steven R. "Cluster Fly" University of Rhode Island GreenShare Factsheets 1999. [20] Once the weather becomes much cooler, P. rudis will seek shelter, usually in homes and buildings. They are very small and white. Pollenia rudis. Pollenia rudis is also known as the attic fly, the loft fly, pollenie du lombric, and the buckwheat fly. [2] The common name, "buckwheat fly", is derived from the odor of buckwheat honey the species gives off when they are crushed. However, cluster flies make their debut in the autumn when they fly to the sunny sides of homes in search of protected over-wintering sites and may be found flying about inside, often in great numbers, throughout the winter. However, it is not a legal authority for statutory or regulatory purposes. The P. rudis larvae are white with posterior spiracles. The typical cluster fly Pollenia rudis is about 7 mm long, has short golden-coloured hairs on the thorax and irregular light and dark grey areas on the abdomen. There are usually about 4 generations per year. It is bigger (8 to 10 mm) than the House Fly and other flies encountered indoors. It is only when there is a sudden drop in temperature that the cluster fly shifts to the interior of structures, holes in trees, loose bark, or other crevices and cavities. Slime and coelomic fluid, from all species of worms tested, induced penetration behaviour. “Pollenia rudis (Fabr.). Cluster flies, Pollenia rudis, are close relatives of blow flies and are similar in size to house flies (3/8-inch) but are more robust in body structure. Immediately after the larvae hatch, they begin looking for worms. larvae on earthworms in the field was found only in Allolobophora chlorotica (Sav.) Specimens in poor condition may lack setae, causing them to resemble P. angustigena,particularly females. Riley, C. V. “The ‘Cluster Fly’” American Naturalist, January 1883. [1] Pollenia rudis is also known as the attic fly,[2][3][4] the loft fly,[1] pollenie du lombric [French],[5] and the buckwheat fly. 1972. There are usually about 4 generations per year. They are dark gray with checkered black and silvery-black abdomens. The number of bristles and setae found on this species are characteristic of this species only. I. “The Taxonomy of the Pollenia rudis species-group in the Holarctic Region (Diptera: Calliphoridae)” Systematic Entomology, 1987. Biology. Urban entomology, which deals with the insects that affect man and his immediate environment,[24] is responsible for investigating economic issues and civil proceedings involving arthropods. Abstract. Wings overlap … P. rudis is also attracted to malt extract, acetyl acetate and the proteins in animal meat. However, the urban subfield of forensic entomology has been closely monitoring P. rudis because of its tendency to infest buildings and its status as a potential disease vector. [3][4] During the autumn and winter months, Pollenia rudis can be found overwintering inside of attics or lofts. When cluster flies do invade the home, they are extremely difficult to exterminate. Pollenia rudis (Fabricius, 1794) Pollenia rudisdiffers from the similar P. angustigenain having two or three anterodorsal setae on the mid-tibiae, rather than one. This fly infests earthworms of the genus Allolobophora but not apparently Lumbricum herculeus. [11], Unlike the majority of blow flies in the family Calliphoridae, Pollenia rudis does not play a large role in the medico-criminal subfield of forensic entomology. Pg 105. They feed on many types of organic matter. [1] Due to cases like these, scientists have investigated the association of Pollenia rudis and its disease vector capability. Cluster flies are generally dark gray with golden yellow hairs on the thorax and irregular light and dark gray areas on the abdomen. Other species of worms were infected in the laboratory. There have been several economically hampering cases of P. rudis infestation around the world. "What is Forensic Entomology" Forensics Entomology 2009. Capinera, John; Heath, Allen. This sluggish species can be found “clustering” near the interior windows of a warm structure. [22] Vacuum cleaners and aerosol insecticides may be used to control visible, sluggish flies, but professional extermination is the most reliable method for eliminating an infestation. of the genus Allolobophora but not apparently Lumbricum herculeus. Scripta Facultatis Scientiarum Naturalium Universitatis Purkynianae Brunensis. [1], In North America, P. rudis eggs generally require 27–39 days to fully develop into an adult. Point of Contact: itiswebmaster@itis.gov. In order to prevent cluster flies from entering a house, all exterior cracks and openings should be caulked or sealed. Cervenka, Valerie J.; Hahn, Jeffrey "Fall Nuisance Flies" University of Minnesota Extension 2008, Mihályi F. “Contribution to the knowledge of the Genus Pollenia R.-D. (Diptera: Calliphoridae).”, Richards P G. Morrison F O. It is important that they find their host quickly, because larvae must penetrate a worm within three days in order to survive. Cluster flies are typically slow moving and pass the winter as adults so are very common in early spring. Complete Metamorphosis. This includes (sealing) light fixtures, electrical outlets, windows, and baseboards. Majorly, the larva feeds on earthworm species, where they develop to pupa while the adult p. rudis is herbivores on organic matter like sap, fruits and flowers (Vincas Buda 270). Description The typical cluster fly Pollenia rudis is about 7 mm long, has short golden-coloured hairs on the thorax and irregular light and dark grey areas on the abdomen. 53(2-3). Cluster flies in North America overwinter in their adult stage, and copulation takes place in the spring. Pollenia rudis (Fabricius, 1794) Pollenia rudisdiffers from the similar P. angustigenain having two or three anterodorsal setae on the mid-tibiae, rather than one. [14], Earthworms are a major source of food for Pollenia rudis. [20] In total, a female cluster fly will lay an average of 100-130 eggs by ovipositing a small group, then crawling or flying some distance before ovipositing each subsequent group of eggs. Without flight, this fly has no way of protecting itself from predators. 103-111. Pollenia rudis, the common cluster fly, is a species of fly in the family Polleniidae. There are three species in the rudis species complex of North America, and the life cycle of each species may differ. Once cluster flies enter a home, they usually hibernate in inaccessible areas between walls and in ceilings until spring when they emerge and seek access to the outdoors. Fertilisation takes place before hibernation, although the males do survive the winter. Host location of first-instar larvae. Development time from egg to adult varies from 27-39 days. The variety of species in North America may account for the discrepancies between European and North American cluster flies life cycles. P. rudis will overwinter until spring, living off of its own fat. They enter houses in the fall and may congregate on the ceiling or at windows. The first instar larvae eat their way through the integument section of the earthworm’s epidermis. [1] The larvae will then molt twice over approximately 20 days and then pupate outside of the host. They are particularly noticeable on warm winter days when they become active and find their way into living quarters. Development time from egg to adult varies from 27-39 days. [20] In Europe, it takes 10–12 months for an egg to fully develop into an adult, resulting in one generation per year. “Cluster Fly, "Cluster Flies" Cornell Cooperative Extension Nassau County 2003-01, Lyon, William F. "Cluster and Face Flies" Ohio State University Extension Fact Sheet. “A Summary of Published information on the cluster fly Pollenia rudis (Fabricus) (Diptera: Calliphoridae).” Phytoprotection. Please contact us if you are having problems with cluster flies in your Wirral property. The stripes on the thorax are not as prominent as on the house fly and the tips of the wings overlap when at rest. Other species of worms were infected in the laboratory. [17], The behavior of the P. rudis fly varies with the annual seasons and conditions of the day. The face fly, Musca autumnalis De Geer, was first reported from northeastern Missouri in, June, 1960. 1st ed. When spring begins and the flies emerge, they appear shrunken because their fat was used up during the winter. An adult female was reared parasitically on the earthworm Allolobophora chlorotica Savigny. [22] They possess the ability to squeeze their bodies through any exterior crevices of a home, such as cracks around windows and doors, air conditioning vents, screening vents, and loosely hung siding. Pg 106. In 1973, a massive infestation of cluster flies in a German Hospital triggered an investigation of the relationship between P. rudis and bacteria pathogen transmission. [25] Careful examination of the flies revealed P. rudis is only capable of transmitting bacteria that causes opportunistic infections. April 26, 2018 The large sluggish flies known as cluster or “attic" flies (Pollenia rudis and relatives) often invade New Hampshire homes in fall and turn into wintertime pests. The aristae are sensitive to minute temperature and pressure changes. [11], The common name "cluster fly" was derived from the clustering behavior in adults of this species in attics and lofts. Lintner, J. The preferred host of the cluster fly, Pollenia rudis Fab., in Ontario is reported to be the earthworm Eisenia rosea Sav. Harris. “An Account of its Dangerous Activities and the Means of Destroying it” The House Fly – Disease Carrier, 1911. pg 236-240. “A Summary of Published information on the cluster fly. [8] The cluster fly is slightly larger than a house fly at 9.525-12.7mm (3/8-1/2 inch) long. Pollenia rudis, the common cluster fly, is a species of fly in the family Calliphoridae.Pollenia rudis is also known as the attic fly, the loft fly, pollenie du lombric [French], and the buckwheat fly. Pollenia rudis Homeowners are accustomed to swatting flies in the kitchen during the summer months. When it is cold these flies tend to find somewhere warm and dry. Because of their clustering ability, they lead to secondary infestations of beetles, carpet … The wings of the adult cluster fly overlap when the fly rests. Ph.D. Thesis, McMaster University, Hamilton, Ont. [8] It is only when there is a sudden drop in temperature[8] that the cluster fly shifts to the interior of structures, holes in trees, loose bark, or other crevices and cavities. Disclaimer: ITIS taxonomy is based on the latest scientific consensus available, and is provided as a general reference source for interested parties. Eggs hatch 0 – 18 hrs (partial development may occur within the female). Cluster fly (Pollenia rudis) Appearance. [3][6][7], This species is widely distributed throughout the United States, Canada, and Europe and is considered a pest species in structures. The species also could have been transported to North America in the ballast of ships containing soil and the cluster fly host, earthworms. The non-biting fungus gnat breeds in over-watered plant soils and may become a nuisance. [21] Each egg is either deposited by itself or in a small cluster of about seven eggs. Pollenia rudis, the common cluster fly, is a species of fly in the family Calliphoridae. [22] However, these methods are not guaranteed for preventing infestations. Pollenia rudis is also known as the attic fly, the loft fly, pollenie du lombric [French], and the buckwheat fly. Richards P. G. Morrison F. O. Size and shape are aids in identification. Cluster flies tend to enter homes and buildings in large masses in late summer or early autumn to seek shelter for the winter months. Description and development The Cluster Fly (Pollenia rudis F.) is a holometabolous insect of the Diptera order and the Calliphoridae family. While feeding, the P. rudis larvae leave the spiracles outside of the earthworm. This sluggish species can be found “clustering” near the interior windows of a warm structure. We do not use these to store personal information about you.Continuing to use this website means you agree to our use of cookies. 27°C) the pupal stage can be as short as 7 days. The ecology of Pollenia rudis (Diptera: Calliphoridae) and its host earthworms (Lumbricidae), with special reference to the host-parasite relationship between P. rudis and Eisenia rosea. Larvae (‘worms' or ‘grubs') hatch in about 3 days and parasitize earthworms in the soil for 11 to 14 days. Immature cluster flies are earthworm parasites. Vol. These earthworms are typically located in well-drained, silt-loam soil with grass cover. Dille, James F.; Kirby, Clay A. Currently there are no reports of P. rudis reducing earthworm populations or causing horticultural problems. The posterior spiracle ranges from yellow in color to light brown. The author concludes that P. rudis may hibernate as an adult, and that the eggs are then laid in April. http://www.ct.gov/CAES/cwp/view.asp?a=2815&q=376718, https://www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=151647, http://www.ento.psu.edu/Extension/factsheets/clusterflies.htm, http://www.varmentguard.com/pestlibrary/CLUSTER%20FLY.pdf, http://www.extension.umnedu/distribution/housingandclothing/DK7579.html, Acta Zoologica Academiae Scientiarum Hungaricae, http://www.pestid.msu.edu/InsectsArthropods/ClusterFlyPolleniarudis/tabid/254/Default.aspx, http://www.forensicentomology.com/definition.htm, https://en.wikipedia.org/w/index.php?title=Pollenia_rudis&oldid=975071869, Articles with dead external links from March 2018, Articles with permanently dead external links, Creative Commons Attribution-ShareAlike License, This page was last edited on 26 August 2020, at 15:47.

"Cluster Flies" The University of Maine Pest Management 2008-19-08http://pmo.umext.maine.edu/factsht/cluster.htm Retrieved on 2009-03-17. P.dasyloda has a black head with yellow tint on the frons. The Cluster Fly.” Ninth Report on the Injurious and Other Insects of the State of New York For the Year 1892, 1893. pg 309-314. These earthworms are typically located in well-drained, silt-loam soil with grass cover. Majorly, the larva feeds on earthworm species, where they develop to pupa while the adult p. rudis is herbivores on organic matter like sap, fruits and flowers (Vincas Buda 270). [8] Once Pollenia rudis enters a home, it is almost impossible to kill enough of the flies to fully eradicate them. Development time from egg to adult varies from 27-39 days. and Eisenia rosea (Sav.). When the larvae mature, they leave the body of the earthworm and pupate in the ground. 53(2-3). Dr. Dall secured specimens of P. rudis for identification. Because of their clustering ability, they lead to secondary infestations of beetles, carpet … You searched for groups matching 'Pollenia rudis' The search string "Pollenia rudis" appears in the following group names or in other names (synonyms, vernacular names) applied to … Eight species are found in Britain and 31 in Europe. A newly emerged fly has many golden hairs on its thorax which may be lost throughout the life of the fly. [1], Adult cluster flies in North America are slow-flying insects that are active during warmer months. [16] They also have aristate antennae. [6][12] P. rudis may have been introduced to the United States upon slow sailing vessels in the cooler months of the year that traveled from Europe. 1972. Pest description and damage Resemble houseflies but with a hint of gold color behind the head. While most blow flies are attracted to rotting or decomposing matter, P. rudis is solely parasitic on earthworms and is unable to complete larval development on carrion. [1][21] The larvae then use their mandibles to penetrate the dorsal side of a worm. Description and development The Cluster Fly (Pollenia rudis F.) is a holometabolous insect of the Diptera order and the Calliphoridae family. Observations on the form and development of the immature stages of Pollenia rudis Fabricius Diptera Calliphoridae are presented. Towards the end of the first instar stage and into the second and third instar stages, the larvae are able to survive longer separations from their hosts. This sluggish species can be found “clustering” near the interior windows of a warm structure. The first reports of cluster flies as pests in homes occurred as early as the nineteenth century, and these flies continue to cause problems today. Common Name: Cluster Fly Scientific name: Pollenia rudis Size 8mm Biology: Eggs are laid in soil cracks and wall cavities these will hatch in about 3 days. It would be tempting to talk about cluster flies such as Pollenia rudis at this point but most in the industry know about their overwintering capabilities as adults, especially in attics. G. ; Morrison,F. If a first instar larva decides to move to another host, it must penetrate its new host quickly in order to survive. Inside the earthworm, the larvae feed until they are ready to pupate. Can Entomol 105:335–341. Scientific name: Pollenia rudis Size 8mm. [4], Attempting to control the cluster fly by controlling their earthworm host is not recommended or effective since flies may originate from more than a mile away from the infestation site. [15] The similarities between pallida and rudis are seen in the female specimens. The flies have also been documented staying in tunnels made by beetles in timber and in animal burrows. [7], All flies can be identified from other species by certain characteristics. [20] P. rudis adults of European origin copulate in the autumn , leaving their first instar larvae in a dormant state in the bodies of earthworms over the winter. [21] Once the host worm begins to decompose and is no longer useful to the larvae, the larvae can either leave to find another host or move to a less decomposed section further down on its host worm. [1], Female cluster flies preferentially oviposit eggs in humid areas with dense surface vegetation and high soil moisture. Dr. Dall also documented the species appearance in Geneva, NY thirty years prior to his publication. During the winter, adult P. rudis' have a habit of overwintering. [5][12][13], The cluster fly is a European species[7] and the date of its introduction into the United States is not known. Cluster flies (Pollenia rudis) are slightly larger than the common house fly, about ¼” to 3/8” in length. 1989. During the autumn and winter months, Pollenia rudis can be found overwintering inside of attics or lofts. Parasitism by Pollenia rudis (Fabr.) These wasps will sting the fly and inject some poison. Cambridge UP, 2002, Byrd, Dr. J.H. During the autumn and winter months, Pollenia rudis can be found overwintering inside of attics or lofts. [23] This unique characteristic makes it uncommon to see this particular blowfly near forensic investigations. ... Common pest of dead rodents/birds etc. General information about Pollenia (1POLLG) THIS WEBSITE USES COOKIES Our website uses cookies to ensure that we give you the best possible online experience. There are usually about 4 generations per year. Complete Metamorphosis. Richards P G. Morrison F O. [6][12] This species gained particular attention in the United States when Dr. W. H. Dall, of the Smithsonian Institution, published an article in the Proceedings of the U.S. National Museum for 1882. There are 2-3 rows of setae located on the thoracic section and 6-8 strong frontal bristles (bristles are thick setae). Adult female flies lay eggs in cracks in the soil in fields, gardens or lawns. Habits: As the days shorten and the weather cools Pesticide appli-cations can be used to kill existing flies for … Howard, Leland O. Pollenia mais, F., is common in most parts of the United States, especially in the autumn, when it frequently seeks hibernation quarters in houses, and again in spring when emerging from hibernation.
