Birch Leafminer
An invasive European sawfly that mines inside birch leaves in North America. Heavy infestations cause extensive browning and premature leaf drop.
Did You Know?
Multiple generations per year cause increasingly severe browning through the growing season.
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.
