Geometroidea		 Family:
Geometridae		Subfamily:
Sterrhinae		Tribe:
Cosymbiini		P3 Number:
91a0017		 MONA Number:
7132.00
Species Status: Forbes (1948) included Pleuroprucha> in the Tribe Cosymbiini
Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLD                                                                                 
Adult Markings: The head, thorax, and wings are all concolorous reddish or greenish-gray; a white bar between the antennae the only contrasting mark (Forbes, 1948). The discal dot is obscure and the postmedian is usually faint, but wavy and marked with points at the veins. The terminal line is fine and black.
Wingspan: 15 mm (Forbes, 1948)
Adult Structural Features: Males with hind tibiae with end spurs only (4 present in females) and otherwise not modified (Forbes, 1948). The forewings are unique among the Sterrhinae in lacking an accessory cell and the radial veins all originating from a common stalk. The hindwing is distinctively arc-shaped. Male antennae are pectinate.
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.

Habitats and Life History
Habitats: Grasslands, fields, and the edges of woodlands (Wagner et al., 2001). We have records from essentially all types of habitats in North Carolina, from maritime forest and grasslands, to Longleaf Pine communities, to peatlands, to bottomlands, to Spruce-Fir forests, to successional fields.
Larval Host Plants: Larvae are polyphagous, frequently found on goldenrods (Solidago) but also reported on a wide range of woody and herbaceous plants. Wagner (2004) specifically lists Mimosa (Albizia julibrissin), ragweed (Ambrosia), indigo-bush (Amorpha), asters, chestnut (Castanea), bittersweet (Celastrus), tickseed (Coreopsis), bedstraw (Galium), sweetclover (Melilotus), oak (Quercus), willow (Salix), goldenrod, and corn. In North Carolina, we have a rearing record of a larva that was feeding on Chinese Elm (Ulmus parviflora). J.B. Sullivan also recorded larvae on Live Oak (Quercus virginiana) and Laurel Oak (Q. laurifolia). - View
