Green Sedge
A free-living caddisfly larva that does not build a case, instead roaming the streambed as an active predator. Adults have greenish wings.
Did You Know?
Unlike most caddisflies, green sedge larvae are caseless predators that hunt like underwater wolves among the stream cobbles.
Thread-waisted Wasp
An elegant wasp with an extremely narrow petiole and red-banded abdomen. It hunts caterpillars and carries them clasped beneath its body to sandy burrows.
Did You Know?
It uses a small pebble as a tool to tamp down the sand plug sealing its burrow, one of the earliest documented cases of tool use in insects.
