Cleonis pigra, the sluggish weevil or large thistle weevil, is a weevil species recorded in Britain and native to Eurasia. It was introduced into North America to help control creeping thistle. [1] This species develops in the roots of plants in the family Asteraceae. [2]

It appears spelled different ways in the literature: Cleonis piger, Cleonus piger, Cleonus pigra, [1] but the correct spelling under ICZN Article 31.2 is Cleonis pigra [3]

It is identified by double V-pattern elytra and a rostrum with three sulci. [1]
