scientific name    Pero behrensaria    

common name     Behr's Pero

Montane conifer forest.

Adults fly in Alberta in June.

Very similar in pattern to other Alberta Pero species, it cannot be reliably distinguished without genitalic dissection (see McGuffin 1987). Behrensaria occurs only in the mountains in association with conifers, and is most likely to be confused with P. honestaria; P. morrisonaria has a lighter, more contrasting forewing median band and P. occidentalis is easily separated from all other Pero by pectinate rather than filiform antennae.

life history
Adults are nocturnal and come to light. Larvae are twig mimics, and the pupa overwinters (McGuffin 1987). The larva is illustrated at http://www.pfc.forestry.ca/entomology/defoliators/loopers/behrensaria_e.html

Restricted range in Alberta, but no obvious concerns.

diet info
Douglas fir (Pseudotsuga menziesii) is a preferred host, other conifers are also eaten (Prentice 1963).

Southern BC and southwestern AB south to CA (McGuffin 1987).
