I thought I was familiar with just about every insect in Texas but this guy has me stumped. When I first spied him I went to get the camera and he flew off before I could get more than 2 pictures. His size I would estimate to be a little over 2 1/2 inches long. I didn't see him do anything to my tomato plant but that proboscis could do some damage to either a caterpillar or a plants stem. I am fairly sure he is a beneficial but I would appreciate any help in identifying him.
