Dispersive flies optimisation (DFO) is a bare-bones swarm intelligence algorithm which is inspired by the swarming behaviour of flies hovering over food sources. [1] DFO is a simple optimiser which works by iteratively trying to improve a candidate solution with regard to a numerical measure that is calculated by a fitness function .
Black flies are very small, just a bit bigger than gnats, and tend to gather in swarms. Stable flies look a lot like a typical house fly, except they have a protruding mouthpart to feed on (mostly ...
Scatopsidae may form swarms of up to thousands of individuals, sometimes including several species at once, possibly for reproduction. Scatopsidae mate in a tail-tail position and mating can last for a long time. One species, Thripomorpha halterata, has been observed doing rhythmic wing movements while swarming, which may be a courtship ...
The Asilidae are the robber fly family, also called assassin flies. They are powerfully built, bristly flies with a short, stout proboscis enclosing the sharp, sucking hypopharynx . [ 1 ] [ 2 ] The name "robber flies" reflects their expert predatory habits; they feed mainly or exclusively on other insects and, as a rule, they wait in ambush and ...
Adult damselflies catch and eat flies, mosquitoes, and other small insects. Often they hover among grasses and low vegetation, picking prey off stems and leaves with their spiny legs (unlike dragonflies which prefer catching flying prey). [22] [23] Although predominantly using vision to locate their prey, adults may also make use of olfactory ...
The Ceratopogonidae (biting midges) include serious blood-sucking pests, feeding both on humans and other mammals. Some of them spread the livestock diseases known as blue tongue and African horse sickness – other species though, are at least partly nectar feeders, and some even suck insect bodily fluids.
Thaumatomyia notata, the yellow swarming fly, is a species of 'fruit flies' or 'grass flies' belonging to the family Chloropidae subfamily Chloropinae. This species is present in most of Europe, in the Afrotropical realm, in the Near East, in North Africa, and in the Indomalayan realm. The adults grow up to 3 millimetres (0.12 in) long.
The genus Pseudacteon, or ant-decapitating flies, of which 110 species have been documented, is a parasitoid of ants. Pseudacteon species reproduce by laying eggs in the thorax of the ant. The first instar larvae migrate to the head, where they feed on the ant's hemolymph , muscle and nerve tissue.
