In some northeastern wetlands, tiny brown butterflies called Bog Coppers feed on wild cranberry flowers. Their habitat requirements are very specific:
“You not only need a bog, but you need the host plant, which is cranberry. They rarely move more than just a few meters away from their host plant,” says naturalist Jerry McWilliams. He says that Bog Coppers are not threatened globally, but they’re imperiled in his home state of Pennsylvania.
“We only have two colonies that are known in western Pennsylvania.”
So protecting their habitat is critical – and it can help other wetland butterflies, too.
“These are beautiful things and they’re so important for pollinating. They’re so important just for the pleasure of life to be able to see them flying around,” says McWilliams.
