I took photos of this insect today. It originally flew around my flowering basil, mimicing the bees, going from flower to flower. Then I saw it grab a bumble bee, to eat it. I wrote about it on my blog today: http://sewartfullyminded.blogspot.com/2010/08/bee-fight-and-bee-killer.html
At first glance I wondered if it was a dragon fly because of the long tail, but it behaved differently. It is fuzzy like a bumble bee but has such huge eyes. I followed it taking photos. It didn’t seem to like that and tried to evade me. It landed on the grape leaf and as I continued to take photos it eventually retreated behind the leaf.
This adept predator is a Robber Fly in the family Asilidae, and we believe, due to its size, that it is in the subfamily Asilinae, but we haven’t the time to research the species at the moment. You may view some possibilities on BugGuide.
