Tamalia
Ericaceous Gall Aphids, Manzanita Leaf Gall Aphids
Tamalia is a Nearctic genus of gall-forming aphids and the sole genus in the subfamily Tamaliinae. Eight described species induce galls on woody plants in the heath family (Ericaceae), primarily on manzanita (Arctostaphylos) and related genera. The genus exhibits a distinctive social system in which multiple foundresses co-occupy galls, a trait that has been exploited by the evolution of socially parasitic inquiline species within the same genus.
