SeasonalityFlies in June (Bowman 1951).IdentificationThe adults are small, slender moths (wingspan 10.5-13.5 mm) with narrow, pale brown to pale yellow forewings (females lighter) and grey hindwings (Davis 1978, Pellmyr 2000). Antennae 27-28 segmented, ocelli absent, maxillary palpi usually 4-segmented and labial palpi 3-segmented (Davis 1978). The immature stages are unknown.
Aenescens was described in the genus Incurvaria (Walsingham 1888), and subsequently placed in Tanysaccus by Davis (1978). Tanysaccus was later found to be a synonym of Lampronia (Nielson and Davis 1985). This species may be conspecific with sublustris, since there do no appear to be any distinguishing traits between the two (Pellmyr 2000).
