Virginian Tiger Moth (Spilosoma virginica) lives in open woods across North America. It feeds on leaves and flowers.
Fascinating facts about the Virginian Tiger Moth
- The adult Virginian tiger moth rests with its wings folded like a tent over its back instead of spreading them flat. Its wings are white and the abdomen is darker, lacking the prominent dark eyes seen in its close cousin. The moth is not poisonous, though the bristles on its body can trigger allergic reactions in sensitive people.
- After finding a mate, the female Virginian tiger moth settles to lay her eggs on the underside of a leaf, arranging them in a single flat layer. Each clutch contains between 20 and 100 eggs. The female is slightly larger than the male in larval form.
- Virginian tiger moths can complete two to three full generations within a single year. One of these generations overwinters, entering a hibernation state during the cold months of temperate regions.
- Yellow woolly bear caterpillars feed by stripping leaf tissue, leaving only the skeletal veins behind, a habit that turns them into defoliators of many low-growing plants. Their diet spans ground cover such as grass and clover, allowing them to thrive in yards and gardens where they are among the most common caterpillars.
- The moth's bristles are harmless in terms of poison, yet they can provoke an allergic response in sensitive people, causing itching or a rash on contact. This reaction is noted despite the species being non-poisonous, meaning the irritation comes solely from the physical hairs rather than any toxin. Consequently, handling the adult Virginian tiger moth may require caution for those prone to skin sensitivities.
