common name     Mottled Euchlaena

habitat
Deciduous forests and parkland.

seasonality
In Alberta flies June and July, peaking late June to early July.

Bright ochre-yellow ground colour with heavy black mottling. The amount of mottling is variable, but no other Alberta Euchlaena has black patches and speckles over most of the wing.

Adults are nocturnal and come to light. The larva, illustrated in Wagner et al. (2001), is mottled brown, and rests in the typical dead-twig posture with only the hindlegs resting on the substrate. This is the most common species of Euchlaena in Alberta.

conservation
Not of concern.

diet info
The favoured larval host is white birch (Betula papyrifera) according to Prentice (1963), with occasional larval collections on also from Salix and Populus tremuloides, Holidscus discolor and Pinus contorta (McGuffin 1981).

range
Coastal BC east to southwestern PQ, south to OR, MO, WI, GA and TX (McGuffin 1981, Wagner et al 2001).
