Entognatha
Orders Protura, Collembola, and Diplura: the entognaths. As we follow the approach to dividing the Class Hexapoda first into the Entognatha and Insecta, recall the reason for this division. All of these are six-legged creatures, a unifying feature. But three of these primitively wingless orders clearly have the mouthparts in an enveloped position and are therefore considered entognathous. This will get us started thinking about separation of insects into orders and what kinds of characters we have to be able to recognize to tell them apart. We will also see that one of these orders includes organisms (springtails) that are extremely common and that we could find virtually everywhere outside in soil and near water, if we were to look more closely.
