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.
Madagascar Tortoise Beetle
A rounded, dome-shaped beetle with transparent margins around the elytra that make it look like a tiny tortoise shell. The center of the shell often displays metallic gold or green coloration.
Did You Know?
The golden coloration fades after death, as it depends on a thin layer of moisture beneath the cuticle that dries out in preserved specimens.
