Often encountered small Rosaceae-feeding Catocala larva across the southern USA. Highly variable, even among siblings, in both color/maculation (tan, gray, brownish, speckled) and A5 horn (nearly absent to quite large, black, orange, gray, red, purplish) and hence tough to separate from other species.... but not an unreasonable first guess in the south for larva without corresponding reared adult. Recorded wild foodplants include several species of Crataegus. (Note disjunct and closely clustered historical records for "titania"-like adults in NJ, DE, PA all dated 1964 to 1971, perhaps a colonization / transplant event from the core midwestern distribution that held for a period of time).
