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.
This triggers sexual maturity in the fleas and they start producing eggs. As soon as the baby rabbits are born, the fleas make their way down to them and once on board they start feeding, mating, and laying eggs. After 12 days, the adult fleas make their way back to the mother. They complete this mini-migration every time she gives birth. [17]
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.

Although many species of flea require a blood meal before they can copulate, that is not the case with Ceratophyllus gallinae. [6] As with other fleas, the life cycle consists of eggs, the larval stages, a pupal stage and an adult stage. [7] The larvae have chewing jaws and it is only the adult fleas that are capable of biting the host.
Crab louse egg on human body hair. The prevalence varies between 0.3% to 4.6% with an estimated average of 2% with an increase during war, disasters and in overcrowding. [9] Crab louse infestations are not considered a reportable condition by many health authorities, and many cases are self-treated or treated discreetly by physicians. [10]
