Adult Markings: A medium-sized Sallow. This winter moth is typically brown with variably contrasting yellow veins. In overall pattern, it is similar to Chaetoglaea sericea, but possesses a dentate rather than even postmedian line. The subterminal line is usually irregular in both species but often has a contrasting pale area immediately following it in Sericaglaea but is more concolorous on both sides of the subterminal in C. sericea. Sexes are similar. |
Wingspan: 40-42 mm (Forbes, 1954) |
Adult Structural Features: The male and female genitalia are reminiscent of those of Metaxaglaea species but are distinct and readily identify the species. |

Adult ID Requirements: Identifiable from good quality photos of unworn specimens. |
Immatures and Development: The larva looks much like many closely related ‘glaeas’. |
Larvae ID Requirements: Identifiable only through rearing to adulthood. |
