For two weeks each year, the termite mounds on the Brazillian Cerrado light up the night. The source of these lights are not the termites, but headlight beetle larvae. The larvae live inside the outer part of mound, only emerging during the few weeks each year when male and female termites take flight. The glowing bodies of the larvae draws the termites like moths to a flame, allowing the larvae to grab and devour them. The larvae collects as many termites as they can and place them in their larder within the mound, which needs to last until the next flying season. This very limited availability of food means that it takes two years for the larvae to turn into adult beetles.
