Comments: One of 74 species in this genus found in North America north of Mexico (Schmidt and Anweiler, 2020), 42 of which have been recorded in North Carolina. This species is placed in subgenus Lepitoreuma by Schmidt and Anweiler, and in the Increta Species Group. Other members of this group in North Carolina include Acronicta albarufa, A. ovata, A. exilis, A. immodica (=modica), A. increta, and A. tristis.
Species Status: Note the change in name! This species was previously named Acronicta haesitata but was recently changed by Schmidt and Anweiler (2020) to Acronicta modica, since the type specimen of A. modica turned out to be what was later called A. haesitata. Conversely, the species that formerly was identified as A. modica is now re-named as A. immodica.
Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLD                                                                                 
Adult Markings: A medium-sized, nearly uniform gray Dagger. The ground color of the forewings is bluish gray, but with small patches of yellowish- or greenish-brown sometimes present, especially in the area between the orbicular and reniform, but not widely suffused across the wing as in A. immodica. The basal area is not darker than the rest of the wing but the antemedian line is typically dark and conspicuous as is the basal dash; as in ovata, the antemedian can be incomplete, not reaching the costa (Schmidt and Anweiler, 2020). The other transverse lines are weakly edged and the anal dash is often diffuse or obscure. Hindwings are pale fuscous. Acronicta immodica is similar in size and pattern but usually has a more diffuse yellowish tinge across the forewings, a less contrasting antemedian line, and sharper and more conspicuous anal dashes (Forbes, 1954; Schmidt and Anweiler, 2020). Neither A. modica (=haesitata) nor A. immodica has a reddish shade at the reniform, unlike specimens of A. albarufa, A. ovata, A. exilis, or A. increta.
Wingspan: 35-43 mm (Forbes, 1954)
Forewing Length: 16.9 mm, males; 18.1 mm, females (Schmidt and Anweiler, 2020)
Adult Structural Features: Apart from size -- which distinguishes A. exilis from the others -- members of the Increta Species Group show essentially no structural differences, including reproductive structures (Schmidt and Anweiler, 2020)
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.

Habitats and Life History
Habitats: Most of our records come from mesic hardwood forests.
Larval Host Plants: Larvae feed mainly on oaks, particularly White Oak (Quercus alba), but have also been reported (but needing confirmation) on beech (Fagus) and chestnut (Castanea) (Wagner et al., 2011). We do not have any feeding records in North Carolina. - View
