Scopula inductata (Guenée, [1858]) - Soft-lined Wave Moth

Superfamily: Geometroidea Family: GeometridaeSubfamily: SterrhinaeTribe: ScopuliniP3 Number: 910578.00 MONA Number: 7169.00
Comments: One of 26 species in this genus that occur in North America north of Mexico (Pohl et al., 2016), seven of which have been recorded in North Carolina
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Covell (1970)                                                                                 
Adult Markings: A moderately small Geometrid. The wings are pale cream or gray and moderately to heavily dusted with brown, sometimes with the brown dominating. They are crossed by five somewhat diffuse lines that are darker gray; the median and postmedian are the strongest (Covell, 1984) and there are small black discal dots on each wing. Inductata is similar but smaller than Scopula limboundata, especially resembling form enuculeata that lacks the dark subterminal shading often found in that species. The lines in inductata are usually paler and more diffuse; they are straighter or more gently curved, running parallel to one another; and the postmedian does not show a strong bulge at the end of the cell or a smaller bulge below it. The basal and median areas are often dusted with darker gray to black scales, whereas these areas are typically clear in limboundata. While the subterminal area can be shaded with gray lines or blotches, these are never as strongly contrasting as in the typical forms of limboundata.
Wingspan: 18-25 mm (Covell, 1984)
Adult Structural Features: The palps are uniformly fuscous in inductata, unlike the bicolored black-and-white palps of limboundata (Forbes, 1948). A photograph showing a side view of the head and clearly showing the palps helps in the identification.
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
