Larval substrate: Unknown
Phenology: Adult: 7/15 to 8/15 (4 records)

Comment: Listed as "nr. sagitella" in K&J, male specimens from Norfolk and Middlesex counties are almost certainly this species and a female from Plymouth county matches these; similar to simplicella, but lacks the long antennal cilia, the antennae instead, as stated in original description are 'finely denticulate beneath' with small hairs emanating from the distal side of each 'tooth'. The tentative female has similar antennae. The discal spots are separate, whereas in simplicella they are joined.
