I, Heather Marcum, shot this emerald ash borer manually with a Nikon D3200 and 40mm lens. My settings were: aperture: f/20; exposure: 1/200; ISO: 4000. These glittering green insects are not something you want to see as they are wiping out the Ash trees in North America. If you do see one of these you should report it to your state's Dept. of Agriculture!!
