LARGE MAPLE SPANWORM AND CURVE-TOOTHED GEOMETER

Curve-toothed Geometer. This species is somewhat similar to the Large Maple Spanworm (above), but the hindwing edge is more jagged or scalloped. 

Large Maple Spanworm. This is a very common species in our area. They are most numerous in August and September, but I have also found a few early individuals in June and July, and one exceptionally late individual on November 8th. 

Another Large Maple Spanworm. Notice that there is a pointed edge on the bottom of each hindwing. Each hindwing ends in a single sharp point. 

This Curve-toothed Geometer was resting in the leaf litter at Sugarcreek MetroPark. It was doing a convincing imitation of a dead leaf. 

I find Curve-toothed Geometers every month from March through September. 

Curve-toothed Geometers are exceptionally good leaf mimics.
