Chasing Butterflies

August 22, 2025

On a warm, sunny afternoon in early April, when it felt like spring might be settling in for good, I went looking for Mourning Cloak butterflies. This butterfly has dark, reddish-brown wings with a lacy-looking yellow edge that reminded someone long ago of the traditional garments worn by people in mourning and they dubbed it a ‘Mourning Cloak’ In Britain, however, they call it a Camberwell Beauty, a name that originated from its discovery in Camberwell, South London in 1748.

I spotted my very first “winter” Mourning Cloak a few years ago in late March while there was still snow on the ground!  The temperature had climbed to a balmy 65-degrees, but I still didn’t expect to see a butterfly floating languidly over a pile of snow!  It seemed so incongruous! Prior to that day in March, I had no idea that some butterflies, like the Mourning Cloak, overwintered as adults!

Butterflies that overwinter as adults tuck themselves away in tree cavities, leaf litter, cracks in rocks, loose bark, and the crevices of unheated buildings in order to survive. When they emerge on a warm spring-like day, they feed on tree sap, particularly from oak and maple trees, to regain their strength. If the cold temperatures resume, which they inevitably do, overwintering adult butterflies head back to their hiding places and wait for warmer weather.

Butterflies that don’t overwinter as adults spend the winter as a chrysalis, a caterpillar, or an egg. Other butterflies, like the monarch, migrate south to find more hospitable accommodations.

When I ventured out in early April looking for a Mourning Cloak butterfly, I was pleasantly surprised to find several of them darting about! I also found a few Eastern Commas, and one tiny Spring Azure butterfly!  Spring Azures don’t overwinter as adults like the Mourning Cloaks and the Eastern Commas, but spend the cold winter months as a chrysalis. In late winter or early spring, they emerge as adults, find a mate, lay eggs, and die within just a few days!

After finding these three different butterflies so early in the season, I was hopeful that I would find even more varieties during the month of May. I went to several different nature preserves over the course of that month and managed to find even more butterflies than I did in April, but most of them were very, very small and not particularly colorful. I LOVE finding the bigger, flashier butterflies like the monarchs, fritillaries, and swallowtails, especially when they land on the bright orange butterfly weed, pink swamp milkweed, lavender bee balm, yellow salsify, or the beautiful magenta-colored ironweed. The combination makes for some stunning pictures.

The collection of butterflies I ended up with in May included a Hobomok Skipper, Little Wood Satyr, Pepper and Salt Skipper, Silver Spotted Skipper, Zabulon Skipper, a Wild Indigo Dusky Wing, Red-spotted Admiral, Viceroy, Eastern Comma, and several Pearl Crescents.

In June, I saw my first Eastern Tiger Swallowtail and my first Spangled Fritillary of the season, plus two small butterflies that were different from the ones I had seen in May: a tiny Eastern-tailed Blue, and a little Essex Skipper. Both have wingspans of about an inch!

July was my very best month for chasing butterflies! There were enough swallowtails, fritillaries, monarchs, viceroys, and red-spotted admirals to keep me happy, and there were a few I hadn’t yet seen during May and June: an American Lady, an Appalachian Brown, a Coral Hairstreak, a Little Glassy Wing Skipper, a Northern Broken Dash, a Northern Pearly Eye, a Tawny Emperor, and an Orange Sulphur. Whew!

August didn’t bring me any new butterflies, but I continued to enjoy the butterflies I had already seen as they fluttered delicately through the various fields of fading summer flowers that I like to visit.

If you want to help overwintering insects like Mourning Cloaks and Eastern Commas, you can start by not cleaning up your yard too early in the spring! Leave all that leaf litter beneath your trees and in your gardens. It’s likely to contain overwintering caterpillars, eggs, or adult butterflies. You can also set up a fruit feeding station in the spring with overripe bananas, cantaloupe, or rotting fruit that will provide sustenance for the mourning cloaks and other butterflies that have been overwintering.

To continue enjoying these wonderful butterflies as well as other creatures, we all need to assume responsibility for maintaining as many natural areas as we can, including our own backyards, and refrain from the widespread use of insecticides!

Habitat loss and the use of insecticides are killing the creatures we love—not just the ones we don’t love!

What saves them, saves us.
