I've been trying, unsuccessfully, for a few weeks to get this shot. Every time I tried the bumblebee would just fly off. But today was the first break in the weather in almost two days, and the critters were more hungry than afraid. I was baiting them on a flower and after getting them acclimated to me I held my finger close to a bumblebee and it took the bait. Probably one of the best proboscis photos that I've taken.
Tech Specs: Canon 70D (F11, 1/125, ISO 200) + a Canon EF-S 60mm macro lens with 25mm of extension )1.7x) + a diffused MT-24EX (flash head "A" set as the key and "B" as the fill, both on the Canon flash mount). This is a single, uncropped, frame taken hand held.
