Fleas Are A Common Wingless External Parasite

by ace

A flea is a typical small wingless insect.

Fleas, being external parasites, live by the hematophagy of the blood of mammals and birds in which they live.

There are several different species of fleas, the most famous of which are:

Cat fleas, Dog fleas, Northern rat fleas, and Oriental rat fleas.

Rat fleas rarely become harmful to the host; in most cases, they are just uncomfortable.

However, there may be a problem when the host experiences an allergic reaction to the flea’s saliva.

Points where fleas bite is usually visible from a swollen, slightly itchy spot with a single hole in the center.

It is important to note that, contrary to what I said above, fleas can transmit diseases.

This is a rare scenario, but it does happen, and an example is the Bubonic plague, where the disease has been transferred between rodents and humans.

If that is not bad enough, murine typhoid fever and even some cases of tapeworm can be transmitted by fleas.

Fleas are small, busy insects and will go through a complete life cycle, from egg to adult, in just two weeks to eight months, depending on environmental conditions.

Generally, after a blood meal, a female flea lays eggs, about 15 a day, and up to 600 in her lifetime. Eggs are usually placed in the host and often leave it.

These flea eggs take between 2 days to 2 weeks to hatch.
