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 ...
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 ...
For example, the flies known as "emergers" in North America are designed by fly fishermen to resemble subimago mayflies, and are intended to lure freshwater trout. [83] In 1983, Patrick McCafferty recorded that artificial flies had been based on 36 genera of North American mayfly, from a total of 63 western species and 103 eastern/central species.
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 ...
Cluster flies (a.k.a. grass flies or attic flies) are flies of the genus Pollenia in the family Polleniidae. Unlike the more familiar blow flies , such as the bluebottle genus Phormia they do not lay eggs in human food.
Hoverflies, also called flower flies or syrphids, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers ; the adults of many species feed mainly on nectar and pollen , while the larvae ( maggots ) eat a wide range of foods.
