scientific name    Autographa flagellum    

common name     Silver Whip

habitat
Clearings, edges and openings in mature mixedwood and deciduous woodland.

seasonality
Adults have been collected in Alberta from late June through mid-August.

identification
A medium-size moth (3.5-4.0 cm wingspan). Forewings are dark grey-brown or brown. The basal, antemedian, postmedian and terminal lines are bordered by pale scales, and are prominent. The most distinctive marking is the large silver stigma, which curves in a gentle arc from the antemedian line to the postmedian line. There is a narrow patch of paler yellow brown scales beneath the outer half of the stigma and large patches of dark brown metallic scales between the postmedian and terminal lines. Hindwings are dark brown with an indistinct discal mark and median band. The antennae are simple and both the sexes are essentially alike. Similar to the smaller A. rubida, but the much larger and more prominent stigma will identify flagellum.

life history
The adults are nocturnal and come to light. There is a single brood each year.

conservation
A widespread but uncommon species. No obvious reasons for concern.

diet info
No Alberta data. Elsewhere, reported larval hosts include Helianthus sp. and Liatris sp.. Like the other members of the genus it is probably a general feeder on herbaceous plants.

range
Newfoundland west across southern Canada to southeastern British Columbia, south in the east to Maine, Michigan and Wisconsin. There are isolated reports from further south (Pennsylvania and Colorado). In Alberta, it has been collected in the Foothills, Aspen Parkland and southern Boreal Forest regions, north to Nordegg and Edmonton. It has also been collected in the wooded valleys in the Grassland Region and in the Saskatchewan Cypress Hills.
