This is the only bioluminescent fungus gnat larvae in North America. Both whitish ends of the larvae emit a blue light used to lure prey. Although they may be common in proper habits, apparently there are very few places in the southeast where they form extensive colonies. One place is Dismal Canyon in Alabama where they are locally called "dismalites". I was invited by my friends who work for the Chattahoochee National Forest to view and photograph the extensive colony at Anna Ruby Falls Recreation Area. Locally the event is called "fox fire" and there are scheduled night hikes to witness the amazing colony. Other than the guided night hikes, after hours entry into the area is prohibited.
