Mimosa Flowerbud Weevil

Coelocephalapion aculeatum

Identification: This species can be distinguished from other species of the Apion-like genera recorded from the Lower Rio Grande Valley by the combination of its comparatively small size, dark reddish legs, the lack of clumped hairs on the elytra, pr

Coelocephalapion buchanani
