Cavariella
Willow-Umbellifer Aphids
Cavariella is a genus of aphids in the family Aphididae, tribe Macrosiphini. It is distinguished from other Macrosiphini genera by a supra-caudal process on abdominal tergite VIII bearing two distal setae. The genus has a Holarctic distribution with approximately half its species occurring in Asia. Species in this genus exhibit a characteristic life cycle involving primary hosts in Salicaceae (willows) and secondary hosts in Apiaceae (umbellifers), making them economically significant as pests of carrot and other crops.
