Comments: One of 103 species in this genus that occur in North America (Gall and Hawks, 2010; Kons and Borth, 2015a,b), 67 of which have been recorded in North Carolina. Barnes and MacDunnough (1918) and Forbes (1954) placed similis in Group XVIII, as its only member.
Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Immature Stages: Wagner et al. (2011)                                                                                 
Adult Markings: The ground color is ash gray (Forbes, 1954). Patches of pale greenish gray are typically present in the basal area, at the reniform, and in an elongated costo-apical spot. The lines are single and black and very distinctive. A basal line is present and the antemedian consists of three outward loops, the middle one particularly broad. The postmedian by itself is highly diagnostic, unlike that of any other of our species of Catocala. It has a sharp, highly retracted bend immediately below the costa and then runs a straight course parallel to the costa, then making a sharp, obtuse bend past the reniform spot, forming another cusp at the end of the cell then running fairly straight across the wing until just before the inner margin, where it makes another sharp inset before terminating. a narrow, straight band of dark reddish-brown usually follows the postmedian. The reniform is typically pale and conspicuous with a less conspicuous pale subreniform just below it. Hindwings are yellow banded with black, with the outer band constricted partway to the anal angle.
Wingspan: 40-45 mm (Sargent, 1976)
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Larvae ID Requirements: Identifiable only through rearing to adulthood.

Habitats and Life History
Habitats: Wagner et al. (2011) state that this species is associated with sandy, dry-oak woodlands with small oaks. Our records come almost entirely from maritime dunes and sand ridges in the Coastal Plain. Only a few records come from the Piedmont and Mountains, with several from dry woodland habitats.
Larval Host Plants: Larvae feed on oaks, including Scrub Oak (Quercus ilicifolia) and Blackjack Oak (Q. marilandica) (Wagner et al., 2011). In North Carolina, J.B. Sullivan reared larvae from Turkey Oak (Q. laevis) and Bluejack Oak (Q. incana). - View
