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 ...
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 ...
Flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups. Their wing arrangement gives them great manoeuvrability in flight, and claws and pads on their feet enable them to cling to smooth surfaces.
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 ...
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 ...
Odonata is an order of predatory flying insects that includes the dragonflies and damselflies (as well as the Epiophlebia damsel-dragonflies). The two major groups are distinguished with dragonflies (Anisoptera) usually being bulkier with large compound eyes together and wings spread up or out at rest, while damselflies (suborder Zygoptera) are usually more slender with eyes placed apart and ...
Dragonfly vision is thought to be like slow motion for humans. Dragonflies see faster than humans do; they see around 200 images per second. [80] A dragonfly can see in 360 degrees, and nearly 80 per cent of the insect's brain is dedicated to its sight. [81]
