Fly killer, bee lover - the secret life of Mentzelia decapetala

Mentzelia decapetala, ten-petal blazingstar, is a mysterious plant. Covered in barbed hairs, it impales small, soft-bodied insects, holding them until they die. But for bumblebees, sphinx moths, and at least one syrphid fly, this plant's evening-blooming flowers are a luminous resource at sunset. This episode is a deep dive into the world of Helena, Montana's Mentzelia patches.
