Taxonomy
Superfamily: Noctuoidea Family: ErebidaeSubfamily: ErebinaeTribe: CatocaliniP3 Number: 930793 MONA Number: 8801.10
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.
Species Status: Described as full species by Brou (2002a). Previously, it had been treated as a form of Catocala ilia.
Identification
Field Guide Descriptions: Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Brou (2002a,b)Technical Description, Immature Stages: Wagner et al. (2011)                                                                                 
Adult Markings: The pattern is very similar to that of Catocala ilia, with both species showing a fairly wide range of variation (see Brou, 2002a). C. umbrosa is generally brown to brownish gray, whereas C. ilia ranges from dark blackish-gray to a somewhat lighter blue-gray. Umbrosa generally shows less contrast between its ground color and markings. In particular, the border and/or filling of the reniform spot is usually a much bolder white in ilia but much less conspicuous in brumosa. In examining North Carolina specimens (S. Hall, pers. obs.), the antemedian line in brumosa appears to be more excurved and more unudulating, especially towards the inner margin; in ilia, the antemedian usually runs straighter across the wing and is usually much more heavily marked. The basal area in ilia is also usually much darker than the median area, whereas the two areas are more concolorous in brumosa.
Adult Structural Features: In males, the end of the valves is more truncated and process of the sacculus is shorter than in Catocala ilia (see Brou, 2002a, for a description and illustrations). Differences in the female genitalia have not been described.
Structural photos
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: Wagner et al. (2011) illustrate a larva and note that it is paler than is typical for C. ilia but probably not always separable.
Larvae ID Requirements: Identifiable only through rearing to adulthood.
Distribution in North Carolina
Distribution: We have records from all provinces of the state

Flight Comments: Univoltine, with records from late May to late July
Habitats and Life History
Habitats: Most of our records come from dry-to-xeric oak-hickory woodlands, including Coastal Fringe Sandhills and Maritime Scrub, corresponding with associations observed elsewhere (Wagner et al., 2011). However, we have at least some records (one confirmed by dissection) from wet-to-mesic stands, including the floodplain of the lower Roanoke River.
Larval Host Plants: Probably stenophagous, feeding on oaks (Quercus spp.). Wagner et al. (2011) state that it is associated with Bear Oak (Q. ilicifolia) in the Northeast, but we have no records from the few Bear Oak sites that occur in North Carolina. - View
Observation Methods: All of our records come from blacklight sampling or from direct observations during the day (e.g., through "tapping"). Like other Underwings, including C. ilia, it probably comes well to bait.

Status in North Carolina
Natural Heritage Program Status:
Natural Heritage Program Ranks: G5 S3S4
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
Comments: Our records are too sparse to determine its status in North Carolina. More needs to be learned about its host plant and habitat associations in North Carolina before an accurate assessment can be made about its conservation needs. More determinations also need to be made via dissection to clearly eliminate possible confusion with Catocala ilia.
