Insect
American Lappet Moth
Phyllodesma americanaAmerican lappet moths are extraordinary dead-leaf mimics whose resting posture perfectly conceals them among dried foliage, with scalloped, reddish-brown wings held flat or tented. Caterpillars feature flattened lateral body flaps, known as lappets, that help them blend seamlessly against tree bark during the day. When disturbed, the caterpillar rears up to expose bright orange or red velvety folds between its thoracic segments, startling potential predators.
