Comments: Both of our species of Microcentrum are excellent leaf-mimics and are very similar in appearance. Microcentrum retinerve is generally a paler shade of green than the dark leaf-green characteristic of rhombifolium, with the head and undersides often shaded with yellowish, and a brown cross line on the stridulatory area of the male (Blatchely, 1920). The structural characteristics described below are, however, probably more reliable in distinguishing the two species.
Total Length [body plus wings; excludes ovipositor]: 20-22mm, males; 24-26mm, females (Blatchely, 1920)Forewing Length: 36-38mm, males; 38-41mm, females (Blatchely, 1920)
Structural Features: The front edge of the pronotum is straight in retinerve but sinuate in rhombifolium, with a slight forward projection at the midpoint (Blatchely, 1923). A good photograph of the pronotum in dorsal view should show this diagnostic feature. The cerci of the males also differ between the two species, with those of retinerve fairly straight and with a blunt tip and those of rhombifolium incurved and mucronate at the tip . The females differ in that the apex of the ovipositor is attenuate or narrowly rounded in retinerve but subtruncate or broadly rounded in rhombifolium (Blatchely, 1920).

Singing Behavior: Songs consist of short series -- three to seven -- of closely spaced, shuffling notes, similar but not as resonant as those of True Katydids, which are often singing at the same time. The songs of rhombifolium are very different, consisting either of a series of well-spaced clicks or single clicks given at longer intervals.
