Known as the fringed looper, the caterpillar has, as the name suggests, short, hair-like fringes along the ventral margin; when apresssed close to a branch, the fringes help break the outline of the body and make the larva nearly invisible (see Ives & Wong 1988). The caterpillars overwinter in the third or fourth instar (McGuffin 1981), likely exposed on bark and branches.
Adults often flush out of shrubby understory during the day, but are primarily nocturnal and come to lights. At northern latitudes where nights are very short or absent during the flight period, adults are diurnal (McGuffin 1981). One of our most common and conspicuous geometrids.
Conservation
Not of concern.
Diet Info
Larvae are generalists on a wide range of deciduous trees, shrubs and conifers. Prentice (1963) reports most larval collections were from Trembling aspen (Populus tremuloides).
Range
Alaska to Labrador and Newfoundland, south to GA, AR, and AZ (McGuffin 1981, Wagner et al. 2001).
