Some intestinal nematodes, such as Ancylostomatids, feed on blood extracted from the capillaries of the gut, and about 75 percent of all species of leeches (e.g., Hirudo medicinalis) are hematophagous. The spider Evarcha culicivora feeds indirectly on vertebrate blood by specializing on blood-filled female mosquitoes as their preferred prey. [1]
In some species, hemolymph has other uses than just being a blood analogue. As the insect or arachnid grows, the hemolymph works something like a hydraulic system, enabling the insect or arachnid to expand segments before they are sclerotized. It can also be used hydraulically as a means of assisting movement, such as in arachnid locomotion.
Mosquitoes, the Culicidae, are a family of small flies consisting of 3,600 species. The word mosquito (formed by mosca and diminutive-ito) [2] is Spanish and Portuguese for little fly. [3] Mosquitoes have a slender segmented body, one pair of wings, three pairs of long hair-like legs, and specialized, highly elongated, piercing-sucking mouthparts.
The two fossilized mosquitoes, both representing the same extinct species, are similar in size and appearance to modern mosquitoes, though the mouthparts used for obtaining blood are shorter than ...
When a female mosquito bites you and sucks your blood, it leaves behind saliva in your bloodstream. Your body reacts to this saliva secretion as an allergen, causing your body to react with a bump ...
Anopheles funestus is a species of mosquito in the Culicidae family. This species was first described in 1900 by Giles. [1] The female is attracted to houses where it seeks out humans in order to feed on their blood, mostly during the night. This mosquito is a major vector of malaria in sub-Saharan Africa. [2]

An individual mosquito can be heard across 2–5 cm in distance when sound level rises to 22-25 dB. [7] Male and female mosquitoes can also be distinguished by their wingbeat frequencies, which are 700–800 Hz for males and 400–500 Hz for females. [7] As a result, flight sounds are used to determine flight activity and distinguish sex of groups.
