Eupatorium perfoliatum
Once common across eastern North America, now almost gone. It feeds on wild bergamot and asters, flowers any yard can grow.
⚠ Supports a species at riskWho this brings back
Supports 5 species at risk.
Disease wiped out most of them. A single bat eats thousands of insects a night, the ones night-blooming natives raise.
It feeds entirely on flying insects. Every native flowering patch is more food in the air it hunts.
Its dusk call is going quiet. It hunts the night-flying moths that evening-primrose and milkweed raise.
Its slow 'pee-a-wee' call is heard less each year. It needs the flying insects native plants support.
