Black on Bone White

[Semicircle]

At dusk black wasps
swarm a hanging basket
filled with deer antlers
and the skeleton of a fawn.
Black on bone white   Skeletons are often bone white.
against gray.   this makes me think of asphalt, but the previous line is a bit of a head scratcher.

I'm not sure if wasps makes for a good title since the poem doesn't focus much on them.

I really like this piece, but I think the last two lines need some reworking, so I can understand it better.
