These are really tiny flies. Most not more than 1/16 of an inch (1.5mm) they are brightly colored but, so small that most people don’t notice them. They are good to have around swampy areas like SW Florida because they eat smaller insects like no-see-ums. Colors range from brilliant blues and greens to golds and coppery reds. The wings are irridescent.
Tech Data: Both of these were taken with the Nikon D90 and 105mm F2.8 VR Micro-Nikkor. I used the SB-800 flash on both. I set the camera to manual mode and let the flash decide how much light was actually needed for the exposure. The Nikon Creative Lighting System is pretty nifty used this way.
