I live in Houston, Texas and this evening I heard a buzzing sound around the lantana. I thought it was a humming bird but when I looked closer I realized it was an insect. It zipped back and forth like a humming bird and when I looked closer I saw it dipping it's tan tongue into each individual flower.

It's an inch-and-a-half to two inches long. It was getting dark so the color may be off a bit but it looked burgundy and brown. It had a very large abdomen that was thick and curved up like a banana. It had a small head and small dark eyes.

There were three of them flying around but they moved too fast to get a picture. I've tried some bug identification databases but I've had no luck. Does anyone have any idea or any hints on where to look?
