|scientific name Semioscopis aurorella |
common name Aurora Flatbody Moth
Can be found in deciduous and mixed forests. Adults have been collected in low latitude boreal habitat as well as in the prairies.
This species is likely univoltine, with a flight period occurring throughout March to late May (Hodges 1974). In Alberta, S. aurorella have been caught between April and early May.
Semioscopis aurorella forewing colouration is variable, ranging from yellow-gray to pale yellow-white (Hodges 1974). Some individuals may have darker forewings but the costal margin is generally gray-brown and flecks of gray scales (Hodges 1974). Forewing length is generally between 11 to 14 mm (Hodges 1974). The aedeagus of male S. aurorella is twice as long as the basal width with short, curved cornuti (Hodges 1974).
Not reported but other members of the genus are leafrollers which overwinter as pupae in the ground (Hodges 1974).
Currently unknown but likely not a concern due to widespread range.
Unknown but the closely related European species, S. avellanella, feed on birch (Betula) and hornbeam (Carpinus) (Hodges 1974).
Semioscopis aurorella ranges throughout Canada between north-central Alberta and south-eastern Ontario (Hodges 1974). In the United States, this moth has been found between south-central New York state and Wisconsin (Hodges 1974).
