A colorful fly.
Old Blue Eyes
Another one that is giving me fits. I KNOW that I have seen this wing pattern somewhere before, but I just cannot dredge it up. I thought at first it might be in the family Ulidiidae, but now am doubtful. This family is poorly known in Colombia - see https://www.researchgate.net/publication/303949973_Catalogue_of_Diptera_of_Colombia_An_introduction
That's an interesting paper. I can see the difficulty. Thank you.
