Brighten up your outfit or bag with one of the most beloved fireflies of North America, Photinus pyralis.

Each summer, the “Big Dipper”, or common eastern firefly, puts on one of nature’s greatest light shows across North America. Using the “lanterns” on their abdomens, males flash yellow-green while flying and dipping low in a unique “J” shape, and females flash a response.

Of course, this patch glows in the dark! Iron on HIGH for years of enjoyment.
