Two small Weevils mating on top of a fence post, not 100% on ID, possibly Dorytomus sp.
No interactions present.
I can't see any reason for that not to be a species of Dorytomus, but I don't know them well enough to confirm it. Do you have any photos taken from above (dorsal view), or a size measurement, or any information about what plant they might have been associated with?
It's a lovely detailed photo.
