|scientific name Apodrepanulatrix litaria |
common name Large Banded Wave
Open montane forest.
The only Alberta record is for August 28th.
A mid-sized, dusky brown geometrid with conspicuously pectinate antennae. Am and median bands diffuse, with a series of dark spots in the subterminal area. Similar to Drepanulatrix unicalcaria, but litaria has a darker hindwing and the forewing is greyish not brown as in unicalcaria.
The light brown larvae have a herringbone pattern, and are presumably cryptic on branches and twigs of the host. McGuffin (1981) gives a detailed description of the immatures, but little information is available on the biology of A. litaria.
Restricted in Alberta to the extreme southwest corner, but widespread in western N. America.
Larvae feed only on Ceanothus spp. (McGuffin 1981).
Southern BC and extreme southwestern AB south to California and Arizona (McGuffin 1981).
