Pulex irritans (Female)

By David Bryson

Photomicrograph of the human flea, Pulex irritans (Female). Fleas are small wingless insects, as adults, laterally flattened, blood-sucking and capable of jumping. The mouthparts are adapted for piercing and sucking and consist of three elongated, sharp piercing elements. The legs are rather long and stout, adapted for clinging with large coxae, and long 5-segmented tarsi. Photographed using focus stacking of each image section then joined using stitching software from 132 photographs.
