Orfelia fultoni
The faint glow of dismalites- the larvae of a keroplatid gnat- is the bluest bioluminescence produced by any known insect. These insects lure prey into sticky silk webs along the mossy wet banks of appalachian ravines and caves. Gatlinburg, Tennessee, USA.
A "dismalite" is a predatory gnat larva found in southern Appalachia that glows blue from both ends of its body as a lure to attract prey. Gatlinburg, Tennessee, USA.
The bluest known bioluminescense of any insect is produced by larvae of a predatory keroplatid gnat, Orfelia fultoni, which lure flying insects to a sticky silk trap. Gatlinburg, Tennessee, USA.
Keroplatidae
Cave webworms are predatory midges whose larvae- like that pictured here- trap prey with sticky silk droplines. Cayo District, Belize.
Several hundred meters into a wet cave, in complete darkness save the illumination of headlamps, predaceous fungus gnat larvae (Keroplatidae) drape sticky draglines to entrap insects that emerge from the running water beneath. Armenia, Belize
