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 ...
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 ...
At any given time, the number of females at a swarm site consists of both those swarming and those resting. The total number of females at a swarm site then includes both the swarming and resting female flies. [4] Swarms generally range from 0.5 to 1.5 m in diameter, with the swarms being 0.5 to 6 m above the ground. [4]
Bibionidae (March flies) is a family of flies containing approximately 650–700 species worldwide.Adults are nectar feeders and emerge in numbers in spring. Because of the likelihood of adult flies being found in copula, they have earned colloquial names such as "love bugs" or "honeymoon flies".

The first aspect is the differentiation of C. frigida from similar looking flies and C. nebularum. The second focus is on the chromosomal inversion of certain alleles to produce flies of differing sizes, and natural selection on certain sizes. The initial discovery of C. frigida was confused due to their variance in size.
