Bee Flea Through Microscope

A bee flea as seen through a microscope.

A Bee Flea is a species of flea (a type of usually blood-sucking insects) that lives by hematophagy (drinking blood) off the blood of Bees, Wasps, and Hornets, but despite its name, it can also suck blood of amphibians, reptiles, birds, and mammals, but unlike most other fleas, they do not carry most diseases, so bee fleas are harmless to humans and dylanusids, but are only harmful to bees, wasps, and hornets due to the diseases they carry that kills only bees, wasps, and hornets. It is also the world's smallest flea, so you could only see them through a microscope, much like other non-insect microscopic animals like mites and others, so it is impossible to see bee fleas, increasing the chance of them becoming invasive species if they infested beehives of even a few colonies of bees. They were originally native to Australia, but ever since human unintentionally introduced bee fleas in other countries, they now live worldwide except Antarctica They are among the reasons why there are bee die-offs, not just climate changes or pesticide, so people are trying to eradicate bee fleas out of existence, but it is impossible to eradicate them once they establish new areas, much like how Formosan subterranean termite is impossible to eradicate once they're established to new areas.
