Superfamily: Geometroidea Family: GeometridaeSubfamily: EnnominaeTribe: OurapteryginiP3 Number: 911401.00 MONA Number: 6964.00
Comments: One of thirteen species in this genus that occur in North America (Ferris and Schmidt, 2010), two of which are found in North Carolina.
Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIFTechnical Description, Adults: Ferris and Schmidt (2010)                                                                                 
Adult Markings: Both species of Tetracis that occur in North Carolina are moderately large, pale species, angular-winged Geometrids with a single straight line (postmedian) crossing their forewings from inner margin all the way 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 cahexiata is a glossier, purer white or ivory than crocallata, which has a stronger yellowish or cream shading. It also lacks the brown dusting and discal spots found in crocallata and the tranverse line is usually narrower and a lighter, more yellowish brown.
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.
