    ID looks plausible to me at face value. Do you happen to have other angles? In particular from the back would be interesting. Posted 4 years ago

      I wish I did, I didn't know I got this shot until I processed the photos. It doesn't seem to be in any other ones We can leave it alone or delete it, whichever you prefer. Posted 4 years ago

        No no no, definitely not delete it. It's a valid observation. Sometimes we only get to a partial ID and just leave it at that. It still has value that way, so no worries.

        I checked the genus and it doesn't seem to have close look-a-likes, so propose we go forward with the ID. We call that a tentative ID. Likely correct, but not 100% sure.         Posted 4 years ago

The Four-spotted aphid fly

The Four-spotted Aphid Fly is the only species in the genus Dioprosopa in North America. This fly takes nectar from flowers and lays its eggs singly on vegetation near aphid colonies. This strategy gives the hatching larva an opportunity to find food immediately and begin feeding on aphids. This fly is an important biological agent controlling Brown Citrus Aphid in citrus growing areas of the US and Puerto Rico.
