Genus Orchelimum
greater meadow katydids

Key to genera of meadow katydids (Conocephalinae).

If, on the basis of the characters in the key, you are uncertain whether Orchelimum is the correct genus for the specimen you wish to identify, these species of Conocephalus may be the source of your confusion:
Identification of species
Most Orchelimum males can be identified by their distinctive cerci. By comparing the dorsal view of the left cercus of a male you wish to identify with the ones in the summary plate below, you should be able to narrow the species you need to consider to one or a very few. (To learn more about a species, click on its cercus.)

illustrations of cerci in Rehn & Hebard (1915a) include lateral as well as dorsal views.

stridulatory areas of males are of some help in species identification, but they are more variable within a species than are the male cerci.

Females of Orchelimum are often easiest to identify by association with males. However, in some species the ovipositor is helpful or even distinctive.
