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.
