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.
Polar Willow Gall Sawfly
A tiny sawfly that induces galls on Arctic willow stems by injecting chemicals during egg-laying. The larva develops safely inside the swollen plant tissue. Adults are small and dark with clear wings.
Did You Know?
The gall provides the larva with both food and insulation, maintaining temperatures several degrees warmer than the outside air.
