Scientists have sought to establish a better state of nomenclatural affairs by creating a set of international names for all living things, but since their names are in Latin, or Latinized Greek, they are seldom practicable for everyday purposes.

A similar insect with long slender antennae is either a katydid (Figs. 23, 24), or a member of the cricket family (Fig. 39).
