Cerura vinula, commonly known as the Puss Moth, is a striking species belonging to the family Notodontidae. This moth is widely distributed across northern Europe; its unique appearance and fascinating larval behavior make vinula a favorite among entomologists and nature enthusiasts. Adult Puss Moths are relatively large for a European species, with a wingspan of 6-7.5cm. Their forewings are pale silver-gray with intricate black markings, giving them a marbled appearance that provides excellent camouflage against tree bark. The hindwings are lighter, often whitish, with subtle markings. Adults are nocturnal and have a short lifespan, during which their primary focus is reproduction since they do not feed.
The larvae of Cerura vinula are most extraordinary. They are bright yellow-green with bold white and black markings, and their appearance changes as they mature. Young caterpillars have distinctive red "tails," which are long, flexible extensions. These tails can be waved or curled when the caterpillar is disturbed, serving as a defensive mechanism with which to startle predators. Older caterpillars develop a pinkish-red head with two prominent black eye spots, making them look intimidating to potential predators. When further threatened, they can spray a mild formic acid as chemical defense - though this is very rare in captive individuals, they should still be handled with care.
The caterpillars feed on the leaves of Woplar (Populus) and Willow (Salix) trees, and their feeding can sometimes cause noticeable defoliation as these caterpillars become large. They pupate in a hard, wood-like cocoon attached to tree trunks or branches, which provides excellent protection during the winter months. The adult moths emerge in spring to begin the cycle again. This is a highly enjoyable species for any skill level!
