On my technique to in other places I discovered … tiny blue lighting fixtures within the woods. I’ve by no means noticed them in particular person however those pictures from Anna Ruby Falls Sport Space within the Chattahoochee Nationwide Wooded area are intriguing. Bioluminescent mushrooms glow inexperienced, fireflies glow yellow-green, however those are blue.
Each and every mild is considered one of two ends of a fungal gnat larvae (Orfelia fultoni). This picture via Alan Cressler, embedded from Flickr, presentations what the larva looks as if right through the day.
Alan Cressler describes them:
Orfelia fultoni, Anna Ruby Falls Sport Space, Chattahoochee Nationwide Wooded area, White County, Georgia:
That is the one bioluminescent fungus gnat larvae in North The usa. Each whitish ends of the larvae emit a blue mild used to entice prey. Even if they could also be commonplace in right kind behavior, it seems that there are only a few puts within the southeast the place they shape intensive colonies. One position is Dismal Canyon in Alabama the place they’re in the community referred to as “dismalites”. I used to be invited via my pals who paintings for the Chattahoochee Nationwide Wooded area to view and {photograph} the intensive colony at Anna Ruby Falls Sport Space. In the neighborhood the development is known as “fox hearth” and there are scheduled evening hikes to witness the fantastic colony. Rather then the guided evening hikes, after hours access into the world is illegitimate.
Fungus gnat larvae are living inside of a slime tube and increase a community of sticky filaments that seize prey which are attracted via the blue glow. The sticky filaments will also be noticed within the pictures.

Within the pictures above, the lighting fixtures don’t glance hooked up however you’ll be able to see how they transfer on this video in New Zealand. The bluish glow worms in New Zealand aren’t the similar species however they have got a an identical look and behaviour.
Again in Georgia the foxfire glows mid-Would possibly via June when the gnat’s larval shape is alive. Evening hikes are introduced right through the ones months however pre-registration is needed and the hikes refill rapid. Don’t wait till Would possibly 2024 to test this web page for Foxfire Evening Hikes at Anna Ruby Falls: https://gofindoutdoors.org/occasions/foxfire-night-hikes-coming-soon/
