Woodland Sunflower

Woodland Sunflower (Helianthus divaricatus). An herbaceous perennial that often grows to 5 – 7 feet tall. It’s native to eastern and central North America and can be found along rocky trails and dry open sites.

As this example, as it dances in the dappled sunlight shows, the leaves are opposite with a smooth to slightly toothed margin and hairy underside.

Butterflies, Silvery Checkerspot (pictured above), Gorgon Checkerspot, and Painted Lady use the Woodland Sunflower as their larval host plant.

An abundance of other insects are attracted to Woodland Sunflowers. Some even to the point of exclusivity. There are certain bees which visit Woodland Sunflowers that will go to only this species of flower, or flowers of the Helianthus, or Sunflower genus. They are said to be oligolectic. Their larvae must be fed the pollen or nectar of those particular flowers in order to develop properly.

Woodland Sunflowers spread by rhizomes forming colonies. In the autumn as the flowers fade those colonies become prime territory for game birds, song birds, and small mammals gathering to enjoy the seeds.

Silvery Checkerspot

Warm sunlight shining through a tiny butterfly wing. Capturing this view of the wings was a challenge. A view that this little critter didn’t want to share. But seeing this, the underside of the wings, makes identification easy. Silvery Checkerspot (Chlosyne nycteis) on Apple Mint (Mentha suaveolens). In this view the hindwing is pale with a large white crescent at the margin. That is a key to identification.

Another Silvery Checkerspot with that same ventral view of the wing. Again the telltale white crescent at the margin.

Adult Silvery Checkerspots seek nectar at many species of flowers including Black-eyed Susan, Apple Mint, Common Milkweed, Red Clover, and Dogbane.

Females lay eggs often a bit more than one hundred at a time on larval host plant leaves that include asters, coneflowers, and sunflowers. In their early larval stages they stay together consuming those leaves. Though they can totally skeletonize those leaves I won’t panic since I know that they’ll turn into precious little butterflies.

Common Buckeye Butterfly

A beauty in the world of butterflies. Common Buckeye (Junonia coenia). It’s common in the southern states, along the California coast and in central America. Also found in other areas of the US, though not as commonly seen.

Here at my cabin I see the Common Buckeye butterfly on apple mint, which is what it’s on in all three of these photos, and on various species of aster.

Common Buckeyes don’t depend on just a single larval host for their eggs and caterpillars but many. A few of these host plants are snapdragon, plantain, ruellia, and toadflax. I look forward to seeing these butterflies every year, and most years I do get to see them. I’ve got my fingers crossed for this year.

Zebra Swallowtail

The larval host of Zebra Swallowtail (Protographium marcellus) is any of the eight species of the genus PawPaw (Asimina). I’m in the process of replacing three PawPaw trees that I recently lost. An important quest for me.

Exquisite Zebra Swallowtails depend entirely on PawPaw trees for their very existence. No PawPaw trees, no Zebra Swallowtails.

They’re native to eastern United States and southeast Canada, the state butterfly of Tennessee.

As adults these butterflies feed on the nectar of flowers such as blueberry and blackberry blossoms, lilac, milkweed, redbud, verbena, and dogbane. They also get minerals from moist sand and soil. But they need those PawPaw trees to get started. I’ve got them ordered. Soon to be put in the ground here at the cabin, and OH! Those blooms. I love ’em!
