A few Asian species use gills to breathe underwater, where they eat aquatic snails and other mollusks. With firefly season almost upon us, their enchanting light displays will soon spark our curiosity and capture our imaginations. Larvae usually eat snails and worms.

Smedley, postdoctoral fellow in neurobiology and behavior; and Jerrold Meinwald, the Goldwin Smith Professor of Chemistry at Cornell and also a member of the National Academy of Sciences. Both male and female fireflies use bioluminescence (biological light) to attract mates. Firefly lights are the most efficient lights in the world100% of the The study employed adult fireflies (which entomologists regard as beetles, not true flies) from the Ithaca, N.Y., area, as well as larval fireflies from Montgomery County in Maryland and Alachua County in Florida.
