Obviously, it’s not spring yet, but with the last few warm days, the butterfly species that hibernate as adults (most butterflies hibernate as pupae, larvae or even eggs) are feeling springtime in the air. Today in Bear Creek I found two species, the earliest date ever for the anglewing, and the second earliest date for the mourning cloak (Eric Eaton saw a mourning cloak in town on the 6th!). These species emerge from the pupa in August, September, October or even November, and then find safe refuge in deep grass clumps or under bark until spring. But 75°F feels a lot like spring to us, and to butterflies as well. the top is the mourning cloak (Nymphalis antiopa) and the bottom the zephyr anglewing (Polygonia zephyrus).
