Thurberia weevil, cotton boll weevil (Thurberia form)
Anthonomus grandis thurberiae is a subspecies of the cotton boll weevil, described by Pierce in 1913. It is distinguished from the nominate subspecies A. g. grandis primarily by its host plant association with wild cotton relatives, particularly Thurberia thespesioides, rather than cultivated cotton.
