Small-headed Stonefly
A large spring-emerging stonefly found in clean upland rivers. Nymphs are predatory, feeding on mayfly and midge larvae. An important bioindicator species.
Did You Know?
Nymphs require the cleanest, most oxygen-rich water of any stonefly, making them sensitive pollution indicators.
Panzer's Nomad Bee
A wasp-mimicking cleptoparasitic bee that targets Andrena mining bee nests. Its bright red, yellow, and black coloring warns predators of its sting.
Did You Know?
It has lost all pollen-collecting structures because its larvae are fed entirely by stolen provisions from mining bee nests.
