💡

Did You Know?

Some Macrocera species have bioluminescent larvae, though less spectacularly than the cave glowworms.

Warble Fly

A large, hairy bee-like fly whose larvae migrate through the bodies of cattle for months before emerging from cysts in the back. Adults have vestigial mouthparts and cannot feed.
