    Saddleback Caterpillar - (Acharia stimulea)

    It is prudent to avoid touching something that looks so strange. Saddleback Caterpillars have stinging spines.

    Staff Writer (8/4/2017): The Saddleback Caterpillar is covered in short hairs that sting when touched and contact can sometimes leave a rash on its human victim. It is a member of the Slug Caterpillar Moth family and has traded in some of their legs for suckers. This allows them to defy gravity and walk along the underside of leaves and branches when feeding. They are not picky eaters and will feed on a variety grasses, trees and shrubs.

    This highly unusual caterpillar becomes a dark brown moth as an adult. The when wings are opened flat, you can see that the moth has a small white spot on its forewings near its body and then two or three white spots near the tips of the wings. The summer season is its most active time of year.
