Aceria baccharices, also known as the mulefat leaf-blister mite and formerly known as Eriophyes baccharices, is a species of arachnid native to North America that induces galls on two California willows, Baccharis salicifolia and Baccharis glutinosa . [1] [2] This mite was first described to science by Hartford H. Keifer in 1945. [3] According to Keifer, "the typical host is the long-leaf type Baccharis which is common to dry washes in northern California. The other host is similar but confined to the south." [3] These galls, which look like warty protrusions from the surface of the leaf, are nurseries for the next generation of mites. [2] The adults eventually leave the leaf via anterior exit holes that may be visible. [2]
Aceria baccharices should not confused with Aceria baccharipha , the Baccharis leaf blister mite. [4]
