Grylloblatta campodeiformis campodeiformis

University of Alberta E.H. Strickland Entomological Museum

IdentificationThe body of these insects is small and pale. They have small eyes made up of about 70 ommatidia and have filiform antennae with 28 or 29 segments, the basal segment being larger than the others. The pronotum is slightly convex, and is longer than it is broad. The abdomen widens from the base to the fifth segment (which is wider than the head), narrowing considerably in three apical segments. The cerci have 8 segments, which become progressively longer towards the apex. In males, the supra-anal plate is roughly triangular, which also has dimensions wider than long. The subgenital plate bears two large, slightly concave, hairy styli as well. Females are 30-34 mm long, covered in a fine pubescence, and have ovipositors shorter than the hind femur. For specimens from known localities, the best method of distinguishing species is geographically, because no subspecies are sympatric. See genus Grylloblatta for general characteristics.
