Bug ID on fruit trees
I think this maybe the same insect as nobueno posted pics of back on 6-9.
I don't have a pic yet, but it looks very much like a small (1/2 the dimension each way) house fly. It is congregating on the ends of branches, one or two to an end, and appears to have its head in close to the branch. Perhaps eating or sucking sap. It does not seem to be eating leaves or buds, at least I have not seen them on green growth or any damage yet. I have seen them on the tips of several fruit trees, apples, plums and cherries. Usually on the trees that are not yet as far along in the bloom.
I'll try to get a pic, but can any suggest what these might be from the description?
