Demotina
Demotina is a genus of leaf beetles in the subfamily Eumolpinae containing over 50 described species. The genus is native to Asia, Australia, and Oceania, with one adventive species (Demotina modesta) established in the southeastern United States. Some species are known to be parthenogenetic. One species, Demotina fasciculata, has been documented engaging in cecidophagy—feeding on plant galls induced by cynipid wasps.
