A glowing fly larva catches prey in sticky webs
Orfelia fultoni larvae inhabit damp places in parts of the United States. They emit blue light and build sticky webs on surfaces such as moss and rock crevices, attracting and catching flying prey. Despite their spider-like webs, they are larvae of a fly.
A beautiful night light can also be a feeding tool.
