The Springtail (Microfalcula delamarei) is a micro-small, wingless hexapod. A hexapod has three pairs of legs (6 legs), but it is not an insect.
It is entognathous, which means that is has internal mouthparts in a gnathal (jaw) pouch. It is in the Collembola class and the Entomobryoidea super-family – like a terrestrial crustacean, because scientists think that it evolved from marine (saltwater) shrimp, crabs, and lobsters. Scientists first thought that it was an insect, but they have now changed the category to an entognathous animal.
The Springtail has three parts: the head capsule, a thorax (with three segments and 6 legs), and an abdomen (with five segments). Therefore, it looks like an insect. It has small antennae, two eyes, and mouthparts. The mouthparts have a pair of jaws. The two eyes are called composed eyes, because they are composed of 8 single eyes. It does not have a throat, so it breathes through a porous cuticle.Continue reading “Springtail”
