   Here’s a varied selection of insects that came in during the last few days while Invert Alert has been having computer problems.


fly caught in mid-hover at 1/3000 second by Gordon Hart.  Jeremy Tatum writes that in the original version of this posting, he had wrongly identified it as a probable Eristalis (Syrphidae).   We are grateful to Claudia Copley for pointing out that it is actually a tabanid of the genus Hybomitra.  Coincidentally, Jeremy Tatum saw a similar one in Goldstream Park on July 11.  It was remarkable how accurately it hovered every bit as well as a syrphid.  The Syrphidae include the attractive flower flies and hover flies (and a few less attractive ones such as the Narcissus Bulb Fly).   The Tabanidae include horse flies and other very painful biting flies.
