Brazilian Railroad Worm
A tropical glowworm beetle with the remarkable ability to produce both green lateral lights and a red cephalic light. The female is large and larviform, while the male is a small, short-lived winged beetle.
Did You Know?
The red and green lights are produced by different luciferases, making this beetle a subject of intensive biochemical research.
Rugose Carrion Beetle
A small, dark silphid with heavily textured, rugose wing cases. It frequents sun-exposed carrion in open landscapes.
Did You Know?
Females lay eggs on carcasses already infested with fly larvae, and their own larvae then feed on the maggots.
