What is the order classification of fleas?

Fleas belong to the order Siphonaptera, which is specifically designated for this group of ectoparasitic insects known for their ability to jump and their blood-feeding behavior. Siphonaptera is characterized by features such as a flattened body, long hind legs adapted for jumping, and specialized mouthparts for piercing skin and sucking blood.

In contrast, the other classifications pertain to different groups of insects. Coleoptera is the order for beetles, which are recognized for their hardened forewings and diverse habitats. Diptera refers to flies and mosquitoes, which are known for having only one pair of wings and usually have a mobile lifestyle. Ametabolous insects are those that undergo little to no metamorphosis throughout their life stages, which doesn't apply to fleas. Understanding the unique characteristics of Siphonaptera helps clarify why it is the correct classification for fleas.
