Dimorphic Tosale Moth
Tosale oviplagalisAlso known as Dimorphic Tosale
Dimorphic tosale moths exhibit dramatic sexual dimorphism, with females displaying rich reddish-brown forewings centered with a pale, oval costal patch, while males are smaller with distinct yellow-brown scaling. Adults fly throughout warm summer nights in eastern deciduous woodlands and surrounding suburban edges. The caterpillars serve as quiet nutrient recyclers, feeding primarily within leaf litter and fallen hardwood leaves on the forest floor.
