Lonchaea chorea is a species of fly in the family Lonchaeidae. It is found in the Palearctic. [1] [2] [3] The larva develops in cow dung. [4]
For terms see Morphology of Diptera. Long 3–5 mm. Male interocular space eye twice as wide as the antenna, more narrow in front. Thorax and abdomen shiny black with blue, green or purple reflections. Wings more or less yellow at the base. Squamae with long marginal cilia. Black halteres. Short subdiscoid abdomen.
Female interocular space slightly less wide than the eye. Lunula with white pruinosity. Antenna dark brown and extended to the epistome.
March–December, on leaves, bushes, shrubs, etc. Larva under old bark, in cow dung, causing decay in beets, under the bark of pine with Tomicus piniperda under Quercus bark.
partial Throughout Europe, from Ireland Sweden to Spain and Italy. Macedonia. Also Ecuador.
The Sepsidae are a family of flies, commonly called the black scavenger flies or ensign flies. Over 300 species are described worldwide. They are usually found around dung or decaying plant and animal material. Many species resemble ants, having a "waist" and glossy black body. Many Sepsidae have a curious wing-waving habit made more apparent by dark patches at the wing end.
Piophila is a genus of small two-winged flies which includes the species known as the cheese fly. As a whole, the genus is often called wine flies; they prefer fermented foodstuffs to deposit their eggs. Piophila vulgaris visits Arum maculatum flowers in England. The genus is found in the Palearctic.
The soldier flies are a family of flies. The family contains over 2,700 species in over 380 extant genera worldwide. Adults are found near larval habitats, which are found in a wide array of locations, mostly in wetlands, damp places in soil, sod, under bark, in animal excrement, and in decaying organic matter. The Stratiomyinae are a different subgroup that tends to have an affinity to aquatic environments. They are diverse in size and shape, though they commonly are partly or wholly metallic green, or somewhat wasplike mimics, marked with black and yellow or green and sometimes metallic. They are often rather inactive flies which typically rest with their wings placed one above the other over the abdomen.
The Lonchaeidae are a family of acalyptrate flies commonly known as lance flies. About 500 described species are placed into 9 genera. These are generally small but robustly built flies with blue-black or metallic bodies. They are found, mainly in wooded areas, throughout the world with the exception of polar regions and New Zealand.
Rhingia campestris is a species of hoverfly, 7–11 millimetres (0.3–0.4 in) long, with a wingspan of 12–18 mm (0.5–0.7 in). It is common across the Palearctic from March until November. It has a broad orange abdomen with a black line along the sides, and has the distinctive long snout of all Rhingia species. Rhingia campestris is the main pollinator for many plant species and due to its long snout it can forage on tubulous flowers. Larvae are associated with cow dung. Adults males feed on nectar, while adult females feed on protein rich pollen, reflecting the cost of developing eggs.
Eristalis pertinax is a European hoverfly. Like Eristalis tenax, the larva of E. pertinax is a rat-tailed maggot and lives in drainage ditches, pools around manure piles, sewage, and similar places containing water with high organic load and low oxygen concentration.
Eristalis arbustorum, the European drone fly, is a Palearctic species of hoverfly that has also been introduced to North America.
Xylota sylvarum is a common Palearctic species of hoverfly.
Eristalis intricaria is a European species of hoverfly. It is a furry bee mimic, superficially resembling Merodon, though Merodon have all black leg tibiae, as opposed to partly yellow. E. intricaria is somewhat variable in colour pattern, and some attempts at naming varieties have been tentatively made. Flight time of adults in the UK are from March to September. It is generally widespread, but is seldom seen in large numbers. Habitat is woodland or marshland.
Neoascia podagrica is a species of hoverfly.
Cheilosia bergenstammi is a widespread European species of hoverfly. Adults can be found in summer visiting ragwort flowers and this plant is also the larval hostplant.
Pipiza bimaculata is a species of hoverfly, from the family Syrphidae, in the order Diptera.
Neoascia meticulosa is a species of hoverfly.
Brachypalpus laphriformis is a species of hoverfly found in Europe.
Xylota florum is a Palearctic species of hoverfly.
Agromyza nigripes is a species of fly in the family Agromyzidae. It is found in the Palearctic. The body is black. The thorax and abdomen are shiny. There are 1 + 4 dorsocentral bristles and 7 rows of acrostical bristles. The wing veins are brown, yellow at the base. Long. : 2-3,5 mm. The larva makes serpentine mines in Medicago sativa leaves.
Nemorimyza posticata is a species of fly in the family Agromyzidae. It is found in the Palearctic.
Agromyza nana is a species of fly in the family Agromyzidae. It is found in the Palearctic. Description of imago-Interocular space red. Antennomeres 1 and II red. Peristoma and palps black. Dorsocentral bristles : 1 +3 subequal; acrostics in four rows. Legs black, knees red. Abdomen black with lighter pruinosity than the thorax. Long.:1,75-2,5 mm. The larva mines Trifolium pratense, Melilotus altissima, Medicago.
Phytomyza affinis is a species of fly in the family Agromyzidae. It is found in the Palearctic. Description of imago-Antennomere III brown black, 1-11 red. Mesonotum matt black lateral parts and notopleural depression yellow. Acrosticals in 2-4 rows. Coxae 1 yellow basally, II-III blackish. Femora yellow. Base of femora, tibiae and tarsi black. Abdomen brown black. Tergites with a yellow apical line dilated at the sides. Long. : 2,5–3 mm. The larva mines Cirsium arvense and also feeds on seeds of Euphrasia.
Platystoma seminationis, the dancing "kiss fly", is a species of fly in the family Platystomatidae, meaning big mouths.
