Eupareophora
spiny ash sawflies
Eupareophora is a genus of sawflies in the family Tenthredinidae, subfamily Blennocampinae. The genus contains at least two species: the West Palaearctic E. exarmata and the Nearctic E. parca. Both species are associated with ash trees (Fraxinus spp.) as hosts. Larvae are characterized by prominent spines and can cause significant defoliation. E. parca has shown rapid population increases in urban settings, suggesting potential as an urban pest.
