The egg is laid singly on the host leaf underside, and hatches in about seven days. Larvae are twig mimics and go through 5 instars, pupating underground in the fall to emerge the following summer (McGuffin 1977). The…
The egg is laid singly on the host leaf underside, and hatches in about seven days. Larvae are twig mimics and go through 5 instars, pupating underground in the fall to emerge the following summer (McGuffin 1977). The immature stages are described in detail by McGuffin (1977) and the mature larva is illustrated by Wagner et al. (2001).
Conservation
The only Alberta record is a specimen collected in 1942. Common and widespread elsewhere.
Diet Info
