Are there Fireflies in the San Diego area?
Not the variety that is so visible in parts of Eastern United States. There are about four species in our area, but none fly about with flashing lights. The females of the pink glow worm, our most easily found species, are larvaform. They maintain the immature larval form and are bright pink as adults. At this stage they glow and can be seen on the ground on warm nights in foothill and mountain areas as a continuous, greenish luminescence. The adult males look like “normal” firefly beetles and fly about in search of the glowing females. The males have the ability to glow, but rarely do so.
