How Fleas Look
It may be difficult to understand how fleas look, so let’s first take a look at the adult flea, which is about an eighth of an inch long. Its body is thin and reddish-brown, with large back legs. In a single leap, it can jump up to 12 inches. It can also hold up to 100 immature fleas in its body. When you see flea bites on your pet, they are probably small specks on your pet’s fur. These are the dried blood from the fleas, which will turn brown when the fleas rehydrate themselves.
Fleas reproduce all year long, although most occur outdoors during warmer months. After eating an insect, the female flea lays an egg. During the next few weeks, the egg will develop into a pupa, which is similar to an adult flea. The flea pupa develops by consuming predigested blood from the host and feeding off the dirt it has deposited in the environment. It will also feed on the eggs of conspecific fleas.
Fleas have six legs and three body segments. Their legs are larger than the other parts, which allows them to jump high. However, they do not have wings, so they cannot fly. The flea’s head has eyes and antennae, which help it track down its prey. It also has sucking and piercing parts.
