P3 Number:
91a1409

MONA Number:
6963.00

Identification

Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)

Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLD

Adult Markings: Both species of Tetracis that occur in North Carolina are moderately large, angular-winged Geometrids. The ground color is uniformly pale and the forewings are marked with a single straight line (postmedian) that crosses their forewings from inner margin to the apex or to the costa just in front of the apex. Other similarly sized, pale Geometrids with a strong transverse line either have more than one line or the line terminates or makes a sharp bend before it reaches the apex. Tetracis crocallata is more yellowish than cahexiata, frequently dusted with light brown, and possesses discal dots that are missing in cahexiata. The transverse line is characteristically darker brown and more contrasting in crocallata than in cahexiata.

Adult Structural Features: Antennae are filiform in both sexes, although the males' are somewhat fasciculate.

Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
