The Western Tussock Moth Caterpillar eats leaves and fruit, and it eats them from a lot of plants. And those beautiful long hairs can cause an allergic reaction too. Mine lasted a couple of days. Western Tussock Moths Caterpillars eat Ceanothus, Oaks (Quercus), Apples, Citrus, Peaches, Roses, Buckwheat, Willow, Adenostoma, Manzanita, Pyracantha, Coffee Berry, and on this rose stem 1st picture and ornamental plum 2nd caterpillar picture here. There are one to two broods per year depending on how long the growing season is. Usually they are out by February and gone by June. The Western Tussock Moth Caterpillar can be an economic pest for nurseries and orchards. The adult females are flightless, you can see the tiny wings of this emerging moth.
