The median area is yellow but heavily suffused with brown towards the base; the subterminal area is a dark, chocolate brown. |
Adult Structural Features: Male genitalia are described in a key given by Forbes (1948) |
Adult ID Requirements: Identifiable from good quality photos of unworn specimens. |
Immatures and Development: A larva illustrated in Schweitzer et al. (2011) is a grayish-brown twig mimic. No technical description was given, however. |
