Field Guide Descriptions: | Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLD | Technical Description, Adults: Forbes (1954); Schweitzer et al. (2011) | Technical Description, Immature Stages: Forbes (1954); Schweitzer et al. (2011) | |
| Adult Markings: A medium-large Papaipema. The median area of forewing is straw yellow, heavily dusted with brown; the basal and outer third of the wing contrastingly fuscous. The spot ring around the reniform is usually yellow and the two spots on the inner side more angulate than in similar species. The hindwings are pale brown with a distinctive yellowish shading at the base (Forbes, 1954; Schweitzer et al., 2011). |
| Wingspan: 35 mm (Forbes, 1954) |
| Adult Structural Features: The valve of the male are illustrated but not described by Forbes (1954) and do not stand out as particularly different from those of several other species of Papaipema. |
| Adult ID Requirements: Identifiable from good quality photos of unworn specimens. |
| Immatures and Development: A larva illustrated by Schweitzer et al. (2011) is yellowish with clusters of dark brown spots on the dorsal and lateral surfaces. Since at least two other species of Papaipema also use Collinsonia as a host plant, Schweitzer et al recommend that they be reared to adulthood in order to identify the species. |
| Larvae ID Requirements: Identifiable only through rearing to adulthood. |
