We are in the season for Goat Moth caterpillar sightings. The caterpillars are unmistakable, pink or dark pink on sides and reddish purple on top, about 100mm or 4 inches long and as thick as a finger. Have you seen one? If so, we’d like to know.

The caterpillars spend many years munching away inside trees. Many species of trees can be host. During late summer many mature caterpillars leave the tree and wander looking for a place to pupate. They may remain in pupa state for years before the adult emerges. June is the usual flight season. It’s the wandering caterpillars that are being seen now. Caterpillars of varying sizes can be encountered at other times of year from trees being cut for firewood. Goat Moth is more common than previously thought. While adults are not often seen, there are caterpillar sightings annually from the SW and mid east region.About 20 sightings have been reported during 2015. Can you add other sightings?
