Sidewalk Darkling Beetle

A common flightless darkling beetle seen walking desert trails at dusk. Its smooth black exoskeleton helps minimize water loss.

💡

Did You Know?

It can survive for weeks without water by extracting moisture from the dry food it eats.

Leaf-Rolling Rose Sawfly

A tiny black sawfly that causes rose leaflets to roll downward into tight cylinders. The larva feeds inside the rolled leaf shelter.

💡

Did You Know?

The female injects a chemical into the leaf margin during egg-laying that causes the leaf to roll tightly, creating a protective tube for the developing larva.
