Fleas are wingless insects, 1.5 to 3.3 millimetres (1 ⁄ 16 to 1 ⁄ 8 inch) long, that are agile, usually dark colored (for example, the reddish-brown of the cat flea), with a proboscis, or stylet, adapted to feeding by piercing the skin and sucking their host's blood through their epipharynx.
The adults are roughly 1.5 to 4 mm in length and are laterally flattened. They are dark brown in color, are wingless, and have piercing-sucking mouthparts that aid in feeding on the host's blood. Both genal and pronotal combs are absent and the adult flea has a rounded head. Most fleas are distributed in the egg, larval, or pupal stages.
The larvae had not been there the night before. The larvae were Apocephalus borealis, a parasitoid fly known to prey on bumblebees and wasps. The phorid fly lays eggs on the bee's abdomen, which hatch and feed on the bee. Infected bees act oddly, foraging at night and gathering around lights like moths. Eventually, the bee leaves the colony to die.
The oldest known flying insects are from the mid-Carboniferous, around 328–324 million years ago. The group subsequently underwent a rapid explosive diversification . Claims that they originated substantially earlier, during the Silurian or Devonian (some 400 million years ago) based on molecular clock estimates, are unlikely to be correct ...
Murine typhus, a rare infection (20-100 cases a year in the U.S.) caused by the bacterium Rickettsia typhi and transmitted by the feces of cat or rat fleas coming in contact with a break in the ...
Being able to tell the difference between, say, a fleabite, a bed bug bite, and a mosquito bite can mean the difference between an infestation (fleas, bed bugs) and figuring out whether the ...
Oklahoma’s hot and dry summers are prime weather for fleas and ticks to find a home on your furry friends. The pesky parasites can not only hurt your pet if not treated but can cause diseases in ...
Belostomatidae is a family of freshwater hemipteran insects known as giant water bugs or colloquially as toe-biters, Indian toe-biters, electric-light bugs (because they fly to lights in large numbers), alligator ticks, or alligator fleas (in Florida). They are the largest insects in the order Hemiptera. [1]
