There are more than 2,000 species of tiny (0.04 to 0.15 inches), wingless, blood-sucking fleas that live on the body of the host they infest. Although fleas cannot fly, they have developed ...
Fleas live by ingesting the blood of their hosts. Adult fleas grow to about 3 millimetres (1 ⁄ 8 inch) long, are usually brown, and have bodies that are "flattened" sideways or narrow, enabling them to move through their hosts' fur or feathers. They lack wings; their hind legs are extremely well adapted for jumping.
This behaviour is a source of one of their alternate names, scuttle fly. Another vernacular name, coffin fly, refers to Conicera tibialis. [1] About 4,000 species are known in 230 genera. The most well-known species is cosmopolitan Megaselia scalaris. At 0.4 mm in length, the world's smallest fly is the phorid Euryplatea nanaknihali. [2]

There is an actual flea species found in the sand – chigoe or jigger fleas – but they do not live in South Carolina. ... due to their small size and weak wings, can only bite on windless days ...
Flexible wings were found to decrease the drag in flinging motion by up to 50% and further reduce the overall drag through the entire wing stroke when compared to rigid wings. [21] Bristles on the wing edges, as seen in Encarsia formosa , cause a porosity in the flow which augments and reduces the drag forces, at the cost of lower lift ...
