Minute Seed Weevils
Ceutorhynchinae is a large subfamily of minute seed weevils within Curculionidae, comprising over 150 genera and more than 1,000 described species worldwide. The subfamily is predominantly phytophagous and exhibits strong associations with Brassicaceae, though host plant relationships vary across genera. The genus Ceutorhynchus is particularly diverse and includes significant agricultural pests such as the cabbage seedpod weevil (Ceutorhynchus obstrictus), as well as species with potential for biological control of weeds. The subfamily shows highest diversity in the Holarctic region, especially the Palaearctic.
