Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012) | Online Photographs: MPG, BugGuide, GBIF, BOLD | Technical Description, Adults: Forbes (1948) | Technical Description, Immature Stages: Forbes (1948); Wagner et al. (2001) | |
Adult Markings: A medium-large, translucent whitish to pale green Geometrid; the sole markings are the relatively straight, antemedian and posmedian lines, both of which are white and bordered medially by green or greenish-brown. Sexes are similar. The species is quite distinct and unlikely to be confused with any other North American species. Tetracis cachexiata has a similar shape but its ground color is off white and the single crossline is dark and quite different in color from that of Campaea. |
Wingspan: 35-50 mm (Forbes, 1948) |
Adult Structural Features: Male antennae are bipectinate except at the apex, which is simple (Forbes, 1954). Pectinations are naked and are attached at the base of the antennal segments. Female antennae are fasciculate. Both pairs of spurs on the hind tibiae are well-developed. Male and female genitalia are quite distinct from those of any species likely to be confused with Campaea. |

Adult ID Requirements: Identifiable from good quality photos of unworn specimens. |
Immatures and Development: Caterpillars are twig mimics with lateral fringes, similar to many caterpillars of Catocala but quite different in shape (more rounded). An extra set of prolegs on A5 along with the fringe of hairs are distinctive (Wagner et al., 2001). |
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants. |
