Catocala mira
Grote, 1876

There are 9 Rosaceae-feeding Catocala whose morphologies overlap and for which separation is tricky in the absence of a reared adult. They are grouped here for comparison: blandula, crataegi, dulciola, grisatra, grynea, lincolnana, mira, miranda and praeclara. More rearing work is needed, but that being said, and with the caveat that all characters vary, there are signposts to follow. Large A5 horn typical for grynea and mira; small horn on blandula and crataegi; horn usually long and characteristically pointed vertically or recurved toward head in miranda; horn stout and bulbous in grisatra. Moderately long multifurcating lateral filaments are the norm, but are longer in the few lincolnana larvae known and shorter in the few dulciola known. Dark dorsal "racing stripes" common in blandula and lincolnana (note also pretiosa). Both blandula and grynea often sport a strongly orange A5 saddle contrasting with ground color. Head capsule of mira usually the only one of these 9 with lobes heavily suffused with black to reddish black (note black lobes in orba). As far as known, foodplant use essentially limited to Crataegus in crataegi, dulciola, grisatra, lincolnana and miranda (note that crataegi has also been recorded on Planera aquatica); praeclara uses Aronia (but so does pretiosa); grynea is principally on Malus, although both blandula and mira use Malus occasionally and Crataegus typically. Habitat for grynea is often suburban, and grisatra appears restricted to open dry sites with Crataegus flava. In the southern Nearctic, the mostly ubiquitous presence of alabamae confounds larval identification for these 9 species.
