Mostly Drosophila-centric. Some of the species we have kept in the lab, quite a lot of fieldwork that we have done around the world. And some just to embarrass people..
Most of the Drosophila photos were taken in the lab with a 28mm prime lens reverse-mounted on extension tubes. More recent ones (and those taken outside) used a Canon MP-E 65mm Macro lens
If you want to see some good pictures of Drosophila, take a look at Nicolas Gompel's photos, or those in the Diptera info album. If you want so see what macro looks like when done by someone who really knows what they're doing, have a look here! And these videos are amazing
