Larva - see photos at in Internet References below.
Invasive from Europe. Retroactively (2009) identified in British Columbia as early as 1980; discovered in Washington in 1998; spreading through most of western Washington and reaching the border of Oregon by 2001; BugGuide record from Los Angeles in 2009. (2)
Larvae are pests of of cultivated and wild cottonwood (Populus). (3) Some sources also list elm (Ulmus), maple (Acer), birch (Betula), heath (Erica) and/or blueberry (Vaccinium) although there is little or nothing in the scientific literature about these potential hosts. The specific epithet would seem to show some early association with maple (Acer) but even that is impossible to confirm.
Life Cycle
The first instar larva mines the leaf. The second instar spins a hibernacula on the bark of a branch and overwinters. Larva reemerges in the spring and bores into a newly developing green shoot. Pupation occurs in leaf litter (Humble, deWaard & Quinn, 2009).
