Virginian Tiger Moth (Spilosoma virginica)


Detailing the physical features, habits, territorial reach and other identifying qualities of the Virginian Tiger Moth.

 Updated: 10/1/2019; Authored By Staff Writer; Content ©www.InsectIdentification.org




Virginian Tiger Moths are actually part of a colorful family though they stick to just white and black themselves.



Adult Virginian Tiger Moths are white with no, or perhaps just a few black spots along the wing. Furry legs are also white with black spots on them. The ventral view reveals yellow-orange patches near the head and black dots on both sides of the thorax. Larger black spots may be on the underside of the hindwing, but not all individuals have them.

The caterpillar of the Virginian Tiger Moth is a rusty orange color and completely covered in thin, long, dark hairs. The bristles are not poisonous, but they can cause skin irritation to sensitive skin. They eat the fleshy parts of leaves, leaving the veins behind. The 'skeleton' remains. This species feeds on cabbage and tobacco plants as well as tree leaves from birch, willow, maple, and walnut. Two to three broods can be produced each year. Late broods can overwinter.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
