Drinking Firefly






The firefly Pteroptyx bearni went straight to a drop of water on a petri dish. They sometimes dive into it, an act that I like to call the ‘suicide mission’ because they drench themselves into that ‘pool’ of water, unable to move and eventually die. I once gave them apple slivers per recommendation of other researchers but I recorded a female Pteroptyx valida sucking water from a damp filter paper. It leads me to think that the fireflies might simply need water.
