FIELD GUIDE DESCRIPTIONS: Covell (1984); Beadle and Leckie (2012) ONLINE PHOTOS: TECHNICAL DESCRIPTION, ADULTS: Ferris and Schmidt (2010) TECHNICAL DESCRIPTION, IMMATURE STAGES:

ID COMMENTS: Both species of 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.

DISTRIBUTION: Please refer to the dot map.

FLIGHT COMMENT: Please refer to the flight charts.

HABITAT: Forests and woodlands (Wagner et al., 2001). We have records from mesic, dry, and shoreline forests in the Piedmont and riparian, cove, and northern hardwood forests in the Mountains.
