and consequently is undisputed, relationships among many endopterygote (e.g., Coleoptera and Hymenoptera) orders are unclear because different data sets present conflicting evidence. Some orders [e.g., Collembola (springtails) and Protura] are considered to be noninsects (placed in the class Parainsecta), but evidence clearly places them in the superclass Hexapoda with insects.

The classification presented here is a snapshot of the current hypotheses of insect relationships. Because the field of systematics that underlies this classification scheme is ever evolving, future arrangements will undoubtedly shift. The extant (or existing) orders of insects, their common names, and estimates of their worldwide species and family richness are listed in Table I.
