Angus' Datana Moth
Datana angusiiAlso known as Angus's Datana Moth, Angus's Handmaid Moth
Angus' datana moths are prominent woodland moths known for their rich cinnamon-brown forewings crossed by slender, dark transverse lines and an elevated, velvety thoracic crest. Caterpillars feed gregariously on hickory, walnut, and pecan foliage, often congregating in dense groups on lower branches before molting. When alarmed, the caterpillars synchronize in a dramatic defensive posture, curling both head and tail upward into a rigid, sharp U-shape.
