Phosflea
this small, glowing gnat was native to the planet Kashyyyk. The Wookiees captured quantities of these insects and kept them in mesh containers. If properly cared for, the phosfleas provided a free, non-polluting light source. The phosfleas were usually caught with a special pheromone-based lure. They gave off a pinkish light. The body of the phosflea was elongated, and protected by a hard, chitinous shell that made them exceptionally durable insects.
