When you see a patch of Pussy Willows look, too for the Mourning Cloak Butterfly. Pussy Willows are the caterpillar host plant for Mourning Cloaks. One of the first butterfly on the wing in early spring, Mourning Cloaks winter over as adults in the cracks and crevises of tree bark.
You may have noticed that the late summer of 2019 has so far been a banner year for migrating Monarchs, as well as other species of butterflies. Not only are reports of good numbers of butterflies being shared all around Boston’s North Shore, but numbers are high across states east of the Rocky Mountains and the southern Canadian provinces. Let’s keep our hopes up that these current high counts will translate to strong numbers at the Monarch’s overwintering sites in Mexico.
I am very often asked, “what is that small Monarch?” Actually, it’s not a small Monarch but a butterfly of an entirely different species, the Painted Lady Butterfly (Vanessa cardui). Every year we see Painted Ladies migrating at the seam time of year as do the Monarchs. Additionally, we are currently in the midst of a Painted Lady irruption. An irruption is a word used to describe a burst in the population numbers of a species.

Here is a butterfly I don’t always see during the late summer migration, a Mourning Cloak. The generation that emerges at the end of the summer spends the winter not as a chrysalis or a caterpillar, but as an adult. They hibernate in the cracks and crevices of trees and buildings.
Mourning Cloaks are one of the first butterflies on the wing in earliest of spring and are a true harbinger of warmer days to come.

In the British Isles, the name for the Mourning Cloak is Camberwell Beauty. I much prefer that name, don’t you 🙂
Here’s how you can help choose the Massachusetts state butterfly –
The choice is between the Black Swallowtail, the Great Spangled Fritillary, and the Mourning Cloak butterflies. All three are beautiful species of Lepidoptera, but as you know from my work, I am partial to the Black Swallowtail. I cast my vote for the Black Swallowtail and here is why. Both the Great Spangled Fritillary and Mourning Cloak are less commonly seen. I’d like children who are developing an interest in butterflies to have the opportunity to get to know their state butterfly easily. Black Swallowtails are widespread and very well-known. In a good year, Black Swallowtails will have two broods. The caterpillars eat plants kids can easily identify and plant, such as carrots, dill, fennel, parsley, and the common wildflower Queen Anne’s Lace. Black Swallowtails are typically on the wing throughout the summer, beginning in early spring through late summer.
On the other hand, the Great Spangled Fritillary caterpillars eat strictly violet plants. This butterfly is usually only seen for about a month, during mid-summer, and has one brood of caterpillars. In our region of Massachusetts, the Mourning Cloak may have a second brood, if we have an early spring, but I only see them in spring, near pussywillows, and again in the fall when they are getting ready to hibernate.
Black Swallowtails are found in backyards, gardens, meadows, marshes, and along the shoreline. They love to drink nectar from wildflowers, including milkweed (as you can see in the short film below) and many, many common garden plants such as lilacs, coneflowers, zinnias, and butterfly bush.

Posting hurriedly today. My darling daughter is arriving Friday for a wedding dress fitting, and I am sooo behind in wedding dress making that I am sure I will be up half the next two nights!
Recently brochures from Rain Forest Publications arrived. Don’t you love pocket guides, for the very reason the name infers–so easy to tuck along when traveling and hiking. That’s my photo on the cover of “Mexico Butterflies.” The photo was taken not in Mexico, but in Gloucester!
Be on the lookout for the first butterfly of spring, which will most likely be the Mourning Cloak Butterfly. Mourning Cloaks do not spend the winter in the cool volcanic mountains of Mexico as do the Monarchs, or as a chrysalis in our gardens, like the Black Swallowtail, or as a caterpillar rolled up in a tight little ball under a leaf, as does the Wooly Bear, but as an adult butterfly!
During the winter months Mourning Cloaks live tucked away in cracks and crevices, between chinks of tree bark, for example. At the first warm breath of spring they begin to take flight, searching for a mate. You’ll often see them on the wing around Pussy Willows, one of the Mourning Cloak caterpillar’s food plants.

Blooming now along the water’s edge and wetlands is our native Pussy Willow (Salix discolor). The first photo is cropped (click to view larger) so that you can easily see the Pussy Willow tree on the far right at the pond’s edge– a pretty pale yellowish-green. The small tree, or large shrub, can either easily be pruned to a standard shape, or allowed to grow in its more unruly, wildy way. Prune the branches down to the ground and the following year you will be rewarded with straight shoots for cutting and bringing indoors. Salix dicolor grows easily in average, wet, and moist areas, and grows best in full- to part-sun.
Pussy Willows are pollinated by wind and by insects and produce a very high-sugar nectar. They are an important early food source for native bees. One Pussy Willow catkin contains about 200 fruit-bearing flowers. Cardinals and finches find the flower buds tasty, too. Willows are dioecious, which means some twigs produce beautiful golden stamens (male parts), while others bear slender greenish pistils (female parts).
I often see Mourning Cloak butterflies around the berm between Niles Pond and Brace Cove; the leaves of the Pussy Willow are a larval host plant (caterpillar food plant) for both the Mourning Cloak and Viceroy butterflies. The Mourning Cloak is one of the earliest butterflies seen in our region because they overwinter in the adult form.
The bark and roots of Pussy Willow contains a compound called salicin, and the herb is used similarly to aspirin in treating mild fevers, cold, infections, headaches, and pain. Aspirin (acetylsalicylic acid) is a synthetic replacement for salicin.
