A handful of Firefly photos from Costa Rica. I’ve been slowly working through photos from this trip a couple of years ago for my website. At this rate my website will be ready to go in a few years.
Despite their name, fireflies are not flies. They are beetles. These beetles produce light via a chemical reaction in their lower abdomen. As larvae the glowing light may act as a warning to predators that they are distasteful or toxic. As adults the light is used in courtship. I never got the opportunity to see any fireflies actually using bioluminescence.
