Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Forbes (1948); Miller et al. (2018)Technical Description, Immature Stages: Forbes (1948); Wagner (2005); Miller et al. (2018)                                                                                 
Adult Markings: One of five Datanas in our area with a smooth outer margin of the forewing. The head is yellowish but the collar, tegulae, and mesothorax are contrastingly dark, reddish-brown. The ground color of the forewing is reddish-brown and is rather evenly colored and not peppered with brown or silvery scales. The lines are bordered outwardly with pale yellow (Forbes, 1948). Datana contracta is similar in pattern but the ground color of the forewings is golden-yellow, strongly peppered with darker brown scales (Forbes, 1948; Miller et al., 2018).
Wingspan: 35 - 50 mm (Forbes, 1948); 35 - 55 mm (Covell, 1984)
Genitalia and other structural photos
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: Larvae are black and covered by long white setae. A white subspiracular stripe is present but the other pale stripes typically found in Datana larvae are present in young instars but often absent or only weakly developed in later instars (Wagner, 2005; Miller et al., 2018). Molting is synchronized and takes place in clusters on tree trunks.
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
