Gymnandrosoma punctidiscanum

The scattered dark dots on the forewings separate this from most other Gymnandrosoma species, which tend toward more uniform or banded patterns. Similar to some Ecdytolopha species, but wing pattern with discrete dots rather than continuous lines or bands. Genitalia examination may be needed for definitive identification.

Deciduous forests, woodlands, and areas with oak and hickory trees. Adults frequently attracted to light in wooded settings.

Eastern North America: Alabama, Arkansas, Florida, Georgia, Illinois, Indiana, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Jersey, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Vermont, Virginia, West Virginia; also Ontario and Quebec, Canada.

Adults active primarily June through August in most of range; possibly bivoltine in southern portions with earlier and later flight periods.

Adults nocturnal, attracted to artificial light sources. Resting posture with wings held roof-like over body, typical of Tortricidae.

Presumed leafroller or borer as larva, based on family characteristics; specific ecological role undocumented.

No documented economic importance. Occasionally encountered by moth enthusiasts at light traps.

• Gymnandrosoma aurantianumLarger, more uniform orange-brown forewings without distinct dot pattern; southern distribution overlap limited
• Ecdytolopha insiticianaSimilar size and habitat but forewings have continuous transverse bands rather than scattered dots
