Time Travel and Hackberry Emperors

Come with me while I do a bit of time travel. Leaving the snow, ice and invigorating cold, we emerge in the sweltering heat and humidity of midsummer. Be sure to bring along your insect spray. Ticks are everywhere. And watch where you step, snakes are active too.

I’ve come upon these photos of Hackberry Emperors (Asterocampa celtis) as I’m going through my innumerable images, giving them keywords, so that I can find them. An ever present task. A must. You wouldn’t believe how many picts I have. Impossible to find things without those keywords.

And here we have brown winged insects. These Hackberry Emperors are not moths but are butterflies. Not impressive colors like many would expect but nonetheless butterflies. The “Hackberry” of its name is this butterfly’s only host plant and is the food source for its larvae. And now, traveling back to beautiful cold winter.

Milkweed Tussock Moth Caterpillar

Milkweed Tussock Moth Caterpillar (Euchaetes egle). This caterpillar just might alarm you if you’re growing milkweed with Monarch Butterflies in mind. No need to worry though. The Milkweed Tussock Moth and the Monarch Butterfly have grown up in the “same neighborhood” side by side, sharing the bounty. Both butterfly and moth caterpillars are eating a poison contained in the milkweed called cardiac glycosides (cardenolides) to provide protection, making both creatures distasteful to birds and bats. As adult moths, the Milkweed Tussock Moth is able to communicate with bats emitting an ultrasonic click which bats take as a warning to stay away. Mighty clever.

Those of us who are growing milkweed to help the plight of the Monarch Butterfly might consider that the Milkweed Tussock Moth would appreciate our help as well. The photo above gives you a glimpse of Milkweed Tussock Moth Caterpillars in various stages of development. Let them dine at the milkweed plants with the Monarchs!

Little Wood Satyr

Little Wood Satyr (Megisto cymela). Not brightly colored. Not large. But this is not a moth but it is a butterfly. Its wingspan is 1.5 to 1.875 inches. They often perch with wings wide open on the leaves of trees or in leaf litter.

Larval host plants are sundry grasses such as Kentucky Bluegrass, Orchard Grass, Centipede Grass and some sedges. As adults they feed on sap, fruit, carrion, aphid honeydew and in unusual occasions nectar. Their caterpillars overwinter in leaf litter, emerging in the spring.

Dark Morph of Eastern Tiger Swallowtail

The world of Nature always boggles my mind no matter what I am studying. There is always something that totally astounds me. One example is the dark morph of the female Eastern Tiger Swallowtail (Papilio glaucus). That’s one in the photo above. Yes, a Tiger Swallowtail. Not yellow, but black. Your location will influence how frequently you’ll see this dark form. The further south the more frequent. In the blog, BackyardWildlifeConnection, Terry W. Johnson says, “In middle Georgia, my neck of the woods, more than 90 percent of all female eastern tiger swallowtails are black.” Another site suggests that 10 percent of female population is the dark morph.

Higher numbers occur in the south because of the prevalence of the host plant of Pipevine Swallowtails (Battus philenor), Aristolochia which imparts a toxin (or an extremely bitter taste) to both the caterpillar and the butterfly. The female dark morph Tiger Swallowtail is mimicking the Pipevine Swallowtail. This mimicry gives these dark females protection, since those Pipevine Swallowtails are often avoided by predators because of their extremely bitter taste.

The dark female Tiger Swallowtail sometimes shows a trace of the tiger stripes, but to see the stripes the lighting must be just right. Very subtle. Males prefer yellow females, but the black form of the female is less attractive to predators so they have a higher survival rate. So yellow Tiger Swallowtails are either male or female. Dark Tiger Swallowtails are always female. Yellow females produce yellow offspring. Dark females produce dark offspring. This is one of those things in the world of Nature that is way beyond “just” impressive.

Sachem

Sachem (Atalopedes campestris). A small grass skipper butterfly with a wingspan of just 1.25 to 1.5 inches. Skippers (Hesperiidae) are a family of butterflies that have the characteristics of both butterflies and moths.

Host plants of Sachem caterpillars are many grasses such as Bermuda Grass, Hairy Crabgrass, Red Fescue, St. Augustine Grass, Indian Goosegrass and Seashore Saltgrass. The Sachem is just one of so many skippers that I’m just beginning to get familiar with.

Gaillardia

Here Gaillardias are growing wild in New Mexico, at Bandelier National Monument. A park I’ve visited many times. And hope to visit many more times.

And more Gaillardias growing wild at Bandelier National Monument. It seems they’re ubiquitous!

It amuses me. My Dad had a thing about digging up Dandelions in his lawn. He was always in a battle with them. That was in Maryland. My father-in-law also had a thing about digging things up from his lawn. The flowers he was in a constant battle with? Gaillardia. That was in New Mexico.

I love Gaillardias. But I must plant them, and care for them. I guess a weed is something that grows where you don’t want it to be.

Gaillardias are in the Sunflower family. Gaillardia is a genus of flowering plants that are native to the Americas. There are twenty-five to thirty species of Gaillardia, annuals, biennials, and perennials. There are also many cultivars.

Many pollinators are attracted to the bright colors of the blooms. Such as the Honey Bee in the previous image, and here a Carpenter Bee.

Butterflies love Gaillardia too. Here a Silvery Checkerspot is enjoying a Gaillardia in one of my gardens.
