This is probably Pachnaeus azurescens

Rostrum seems a bit too long for P. opalus but I can't make out the rostral carinae well enough to be positive.

Pachnaeus azurescens is a superficially very similar and apparently very closely related Cuban species that has become established in the past few decades in the area east of Tampa bay. There are a number known Floridian records mostly scattered around the Lakeland area. The primary means to separate the species is sculpture of the epifrons, which isn't clear in most photo records.

Rather Pachnaeus opalus

Thank you

Thanks for the correction Mike. I honestly wasn't sure if Artipus is even known on the gulf coast, but the particularly small size had me thinking Artipus. What is the best way to distinguish these two visually (particulary by photo)? Would it be the slight greenish tint and less mottled elytra?

Entiminae

Appears to be one of the broad-nosed weevils in the subfamily Entiminae. My thoughts would be Artipus floridanus, but the elytra looks too smooth, although the color and the lack of spines on the hind femur is consistent with A. floridanus.
