Larval substrate: Quercus ilicifolia* (Scrub Oak), Quercus rubra* (Northern Red Oak), Quercus velutina* (Black Oak)
Phenology: Adult: 8/11 to 8/13 (2 records)

Comment: S. nigriverticella and S. macrocarpae can be very difficult to distinguish, although the males of nigriverticella have androconial scales on the hindwings. S. nigriverticella apparently tends to have a narrower fascia than S. macrocarpae and is more common than macrocarpae in eastern NA
