💡

Did You Know?

The broadly expanded margins of its shell-like body can be pressed flat against a leaf surface, creating a sealed edge that is nearly impossible for predators to breach.

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.
