Technical Description, Adults/Nymphs:

Comments:
A small green and yellow Lesser Meadow Katydid. Head, thorax, and the anterior portion of the abdomen are green, shading into bright yellow on the posterior portion of the abdomen, with the cerci also bright yellow in the males (Blatchley, 1920). The face lacks the median stripe found in O. stictomerus, but there is a broad stripe of cinnamon-brown on the dorsal surface of the head and pronotum (Rehn and Hebard, 1920). The tegmina are light buff, and the hind femora are green, lackng the prominent reddish spots found in stictomerus (Blatchley, 1920).
Total Length [body plus wings; excludes ovipositor]:
12-15 mm, males; 11.6-17.2 mm, females (Blatchley, 1920)
Structural Features:
Both macropterous and micropterous individuals exist. In micropterous individuals -- which predominate -- the tegmina cover three-fourths of the abdomen in males and two thirds in females; the tips are obliquely and sharply rounded (Blatchley, 1920). The cerci of the males are strongly swollen at he middle, with the apical portion abruptly, strongly narrowed; a slender tooth is located on the ventral side, with the base not visible from above (see Rehn and Hebard, 1915, and Blatchley, 1920, for illustrations and descriptions; also illustrated on SINA). The ovipositor is straight, relatively broad, and shorter than the hind femora (Rehn and Hebard, 1915; Blatchley, 1920; also illustrated by SINA, 2018).
