Finger-net Caddisfly

Its silk nets have an incredibly fine mesh, filtering particles as small as one micrometer.
Blue Ghost Firefly
A firefly producing a steady pale blue-white glow rather than flashing. Females are larviform and wingless, glowing softly on the forest floor.
Did You Know?
Males fly slowly just above the leaf litter, creating an ethereal drifting glow that gives them their ghostly name.
