A flea can jump 60 times its length in height and 110 times its length in distance, equivalent to a 1.8 m (6 ft) adult human jumping 110 m (361 ft) vertically and 200 m (656 ft) horizontally. Rarely do fleas jump from dog to dog. Most flea infestations come from newly developed fleas from the pet's environment. [6]
Tunga penetrans is a species of flea also known as the jigger, jigger flea, chigoe, chigo, chigoe flea, chigo flea, nigua, sand flea, or burrowing flea. It is a parasitic insect found in most tropical and sub-tropical climates. In its parasitic phase it has significant impact on its hosts, which include humans and certain other mammalian species.
The flea eggs are about 0.5 mm in length. They are oval-shaped and pearly white in color. Eggs are often laid on the body of the host, but they often fall off in many different places. The larvae are about 0.6 mm in length. They are creamy white or yellow in color. Larvae have 13 segments with bristles on each segment.
From ticks to spiders to bed bugs, here’s what the most common bug bites look like in photos, the symptoms to know, and whether or not they can be dangerous.
The chigoe flea eggs’ average length is 604 μm and the just hatched larvae, in their first instar, have an average length of 1,500 μm. At the second and last instar ( T. penetrans is unique among the fleas in that it only has two, instead of three, instars.) the larvae decrease in size to 1,150 μm after growing to at least 2,900 μm.
Echidnophaga gallinacea, also known as the hen flea or sticktight flea, is part of the 2,500 known flea types in the Siphonaptera order.

The aim of the Handbooks is to provide illustrated identification keys to the insects of Britain, together with concise morphological, biological and distributional information. The series also includes several Check Lists of British Insects. All books contain line drawings, with the most recent volumes including colour photographs.
The females lay eggs in soil, which has plants growing nearby. The eggs hatch in 7 to 14 days into larvae. While in their larval stage, their small, worm-like bodies are white. The larvae feed especially on plants' roots, causing serious damage. Then, they transform into pupae, and a week later, into adults. [5]
