How Do Fleas Grow in Size?

Fleas are flat, wingless insects that are about 3 millimetres in length. Their flattened bodies make them easy to move through a host’s fur. They lack wings and have three pairs of stylets, the middle of which is used to extract blood from the host. Fleas also have a front section with glands that produce an oily substance. The oily substance makes the flea shiny, which helps it move through the fur of its host.

Fleas are small, wingless insects that are brown or reddish-brown in color. Their hind legs are large and modified for jumping. They can jump 12 inches horizontally and eight inches vertically, depending on the species. Fleas are able to jump because their hind legs are long and flexible. Fleas can live in areas with warm, moist temperatures. If you notice fleas on your pet, look closely at their bodies. Fleas can be a nuisance to you and your pet.

Flea larvae are about one-eighth inch long and white. They live for four to eighteen days in their larval stage. Once in this stage, they spin a silk cocoon to enter their pupal stage. The pupae live for approximately three to twenty days, depending on their environment.

Adult fleas feed off of their host. When your pet moves, they shed flea eggs, which hatch into larvae. These larvae will then grow into adult fleas.
