|scientific name Lampronia aenescens |
Open grassland where rose shrubs are present (Pellmyr 2000).
Flies in June (Bowman 1951).
The 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).
The larval hostplant is Common Wild Rose (Rosa woodsii) (Pellmyr 2000).
In Alberta, recorded from the Waterton region (Bowman 1951). Ranges west and south through southern B.C. to northern California and Colorado (Pellmyr 2000).
