Villa modesta is a species of fly in the family Bombyliidae. [1] The larvae may feed on larvae of Lepidoptera.
Villa modesta can be found in June to September in coastal dune areas throughout mainland Europe, in Britain and to the north in Norway. [2] [3] [4]
Villa modesta is a fairly large fly, the body length is 10–14 mm. The body is brown. The female has pale bands on tergites 2,3 and 4. The male does not have bands but has tufts of hair at the end of the abdomen and at the base of the wings. The wings are transparent with a narrow brown front margin.
Like many other bombyliids, the eggs are flicked by the adult females toward dark holes. The females may be found hovering near a dark hole in the sand shooting eggs. An animation, 6 times retarded, is given here.
Every now and then the females are rubbing the abdomen in the sand in a small circular movement. Sand is necessary to make the eggs less tacky. To this end the females do have a sand chamber. [5] An animation is given here.
The males have a choice between two strategies to gain access to a female. The males may search through the vegetation for females. When a female has been found the male will go into a hovering state near the female as given in this animation.
The males may also choose a sit and wait strategy, sitting in the sand and chasing after passing females.
Flies are insects of the order Diptera, the name being derived from the Greek δι- di- "two", and πτερόν pteron "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing an estimated 1,000,000 species including horse-flies, crane flies, hoverflies and others, although only about 125,000 species have been described.
Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies, which constitute the other odonatan suborder, Anisoptera, but are smaller and have slimmer bodies. Most species fold the wings along the body when at rest, unlike dragonflies which hold the wings flat and away from the body. An ancient group, damselflies have existed since at least the Lower Permian, and are found on every continent except Antarctica.
The Bombyliidae are a family of flies. Their common name are bee flies or humbleflies. Adults generally feed on nectar and pollen, some being important pollinators. Larvae generally are parasitoids of other insects.
The Phoridae are a family of small, hump-backed flies resembling fruit flies. Phorid flies can often be identified by their escape habit of running rapidly across a surface rather than taking to the wing. This behaviour is a source of one of their alternate names, scuttle fly. Another vernacular name, coffin fly, refers to Conicera tibialis. About 4,000 species are known in 230 genera. The most well-known species is cosmopolitan Megaselia scalaris. At 0.4 mm in length, the world's smallest fly is the phorid Euryplatea nanaknihali.
Poecilanthrax willistoni, Williston's bee fly or sand dune bee fly, is a member of the Bombyliidae insect family. This family includes the bee flies, true flies that have developed Batesian mimicry characteristics to avoid predators. That is, they look like bees because that helps them avoid bee-wary predators, but they lack stingers.
Eristalis tenax, the common drone fly, is a common, migratory, cosmopolitan species of hover fly. It is the most widely distributed syrphid species in the world, and is known from all regions except the Antarctic. It has been introduced into North America and is widely established. It can be found in gardens and fields in Europe and Australia. It has also been found in the Himalayas.
Bombylius major is a parasitic bee mimic fly. B. major is the most common type of fly within the Bombylius genus. The fly derives its name from its close resemblance to bumblebees and are often mistaken for them.
Eristalinae are one of the four subfamilies of the fly family Syrphidae, or hoverflies. A well-known species included in this subfamily is the dronefly, Eristalis tenax.
Phasia hemiptera is a fly belonging to the family tachinid.
Progomphus borealis is a species of dragonfly in the family Gomphidae. This dragonfly species is commonly known as the gray sanddragon.
The Hudsonian whiteface is a species of dragonfly in the family Libellulidae. Its common name comes from where it is found, Hudson Bay.
Trichopoda pennipes, common name feather-legged fly, is a fly in the family Tachinidae.
Sargus bipunctatus, the twin-spot centurion, is a European species of soldier fly.
Dryomyza anilis is a common fly from the family Dryomyzidae. The fly is found through various areas in the Northern hemisphere and has brown and orange coloration with distinctive large red eyes. The life span of the fly is not known, but laboratory-reared males can live 28–178 days. D. anilis has recently been placed back in the genus Dryomyza, of which it is the type species. Dryomyzidae were previously part of Sciomyzidae but are now considered a separate family with two subfamilies.
Lutzomyia shannoni is a species of fly in the subfamily Phlebotominae, the phlebotomine sand flies. It is native to the Americas from the southeastern United States to northern Argentina. It has a disjunct distribution, and is only found in regions with suitable climates, habitat types, and host animals. It is well known as a vector of the vesicular stomatitis virus, which causes the disease vesicular stomatitis in animals, particularly livestock.
Bibio pomonae, common name red-thighed St Mark's fly or heather fly, is a species of fly (Diptera) belonging to the family Bibionidae.
Anthrax anthrax is a species of fly in the family Bombyliidae. Unlike, for example, Bombylius major, this species does not mimic a bee. The eggs are flicked by the adult female toward the entrance of the nests of mason bees. After hatching, the larvae find their way into the nests to feed on the bee larva. A. can be found in May to August throughout mainland Europe. In the Netherlands A. anthrax is a common visitor of insect hotels. It was first recorded as breeding in Britain in 2019.
Bombylius canescens, is a species of bee-fly belonging to the family Bombyliidae.
Spilomyia longicornis is a species of syrphid fly, also known as a flower fly or hoverfly, in the family Syrphidae. Although the appearance of S. longicornis is remarkably similar to a vespid wasp, it is a fly and cannot sting. It occurs in North America, east of the Rocky Mountains.
Bezzia nobilis is a species of biting midges in the family Ceratopogonidae. It is widely considered one of the most common Bezzia species; it is found in Eurasian regions, all over the United States, Central America, and even into South American countries like Brazil. B. nobilis seem to prefer aquatic environments; they are commonly observed in stagnant water pools in Eurasia regions and marshes in the southern United States. Adults of this species are easily distinguished by their black and yellow striped legs. Pupae are recognized by their brown bodies, abdominal spines, and respiratory horns. B. nobilis larvae are distinguished by brown heads and white bodies. Little information is known on their life cycle or mating habits. B. nobilis is a predatory species. While some research suggests they mainly feed on larvae of other insect species, experiments suggest they prefer immobile, easy prey such as dead adult flies, bacteria, and protozoa.
