Birch Leaf-Roller Sawfly
A flat-bodied sawfly with long, thread-like antennae and a broad abdomen. Larvae roll birch leaves into tubes using silk and feed inside these shelters.
Did You Know?
The larva creates an elaborate rolled-leaf shelter that protects it from both predators and weather while it feeds inside.

A large darkling beetle with deeply pitted elytra found in North African deserts. It is primarily nocturnal, sheltering under stones by day.
Did You Know?
The deep pits on its shell may help trap air for insulation against extreme temperature swings.
