Thank you. I thought that spur was important. I'm not familiar with that term "eye gnats". Can you explain that comment? Is that just a common name for the group?

There are a few species of chloropid flies in which the adults are attracted to eyes, open wounds or even sweaty skin. In some places, at the right time of year, this can get pretty annoying or even dangerous because they can transmit conjunctivitis as well as some livestock diseases (e.g., yaws). Some Hippelates, Liohippelates and Siphunculina have this habit in North America. One of the best ways I've found to collect Hippelates in southern Canada is to sit outside in a field on hot summer days and wait for them to land on my arms.

For some reason I thought "eye" referred to the fly's eyes. It never dawned on me that it referred to eyes of another animal.

Now pictures of starving children in Ethiopia are coursing through my mind.
