Wandering Salamanders eat a variety of small invertebrates, including ants, beetles, spiders and mites (Storm and Allen 1947). The following information on the diet of this species is provided by
AmphibiaWeb (2009): As with most salamanders, the Wandering Salamander is a generalist feeder. In California, the Wandering Salamanders diverse diet consisted primarily of hymenopterans (ants), coleopteran adults and larvae, isopods, and collembolans (Bury and Martin 1973). In a population in British Columbia, hymenoptera (ants), coleopterans, and gastropods were significant prey items in terms of both frequency and prey volume (Stelmock and Harestad 1979). Acarinians (mites) and collembolans had a high frequency of occurrence but their contribution to total prey volume was slight (Stelmock and Harestad 1979). Juveniles eat smaller prey than do adults (Stelmock and Harestad 1979).
