Curve-toothed Geometer


Another nod to moths in celebrating National Moth Week (July 17-25, 2021). This moth photo was in my immense file of moth images, unidentified. Many of you might know, I love a mystery and last night I looked upon this critter as one of those mysteries. Luck was with me and I was able to figure out that this is a Curve-toothed Geometer (Eutrapela clemataria). A master of camouflage in both adult and larval form. Here, as a moth the camouflage isn’t that effective against the cedar siding, but imagine this moth in a bunch of leaves and you can appreciate how clever the coloring and shading is. The caterpillar is just as ingenious, an inch-worm disguised as a stick. A stick that loves to eat the leaves of many trees. Just a few of those trees: ash, basswood, birch, elm, fir, maple, poplar, and willow.
