Weevil Sp?
This turned out to be quite complicated.
There are a fair number of small green weevil species and they fall into two familes apparently.
Phyllobius & Polydrusus Weevils.
They both feed on the foliage of various plants. In this casing mating on Dogwood.
The families can be separated by the insertion point of the antennae. In all Phyllobius species the insertion point is visible from above. In Polydrusus species this is not the case.
Another caveat is that not all Polydrusus species are green.
An introduction to this identification conundrum can be found on
Phyllobius Weevils at Eakring Birds
In this case the antennae insertion points appear to visible form above so a Phyllobius Sp
Needless to say there is another family in the melting pot - Pachyrhinus, which looks similar to both Phyllobius & Polydrusus species.
