Bark-crevice Rove Beetle
A slender, flattened rove beetle adapted for life under tight-fitting bark. Its compressed body and strong legs allow it to navigate the narrow subcortical habitat where it hunts bark beetle larvae.
Did You Know?
This beetle is considered a natural enemy of the European spruce bark beetle and helps regulate bark beetle populations in managed forests.
Railroad Worm
A beetle larva with 11 pairs of green-glowing lateral organs and a red-glowing headlamp — the only land animal that produces two different colors of bioluminescence simultaneously.
Did You Know?
The railroad worm is the only terrestrial animal that glows in two colors at once — green along its sides like railway car windows and red on its head like a locomotive.
