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.
Diurnality, plant or animal behavior characterized by activity during the day and sleeping at night. Cathemeral, a classification of organisms with sporadic and random intervals of activity during the day or night. Matutinal, a classification of organisms that are only or primarily active in the pre-dawn hours or early night.
The larva of the cat flea has a grub-like appearance and is ~2 mm in length. The larvae are negatively phototaxic/phototropic, avoiding light and hiding in the substrate around them. The larvae require adequate ambient moisture and warmth, and will die at temperatures near freezing. [8] Cat fleas prefer soil moisture content between 1-10%. [12]
Some people think there are insects called sand fleas that bite you. But some experts say the creature that bites you and the sand flea are likely entirely different beasts.
The jumping is found to be initiated when the intensity of light is reduced. [10] The host is infected during the spring, when it is foraging on the ground. [11] Fleas like C. gallinae that are found in nests often develop a defined breeding season, which coincides with that of their host. Associated with this is their ability to survive away ...
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]
Fleas (Siphonaptera) such as Echidnophaga gallinacea, range from 2–6 millimetres in length and have bodies which are flattened laterally or appear compressed horizontally when viewed from above. [9] [12] The flea's body is designed to easily travel through hairs or feathers, allowing free movement throughout the host's body.
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.
