So many thanks to my new friend Lauren, who generously shared cuttings from her American Birch Tree growing in her fantastic habitat garden. Her garden paradise is a pollinator’s dream, filled with gorgeous flowering and fruiting trees and shrubs, native wildflowers, and non-invasive well-behaved ornamental plants. While we were chatting, a Monarch flew on the scene, pausing to nectar at her butterfly bush! Mothra and her siblings thank Lauren, too.

Mothra!

Cecropia Moth caterpillar copyright Kim SmithNoticeably growing larger day by day, the biggest caterpillar of our batch of Cecropia Moth caterpillars (nicknamed Mothra) still has a ways to go before he/she pupates and becomes a cocoon for the winter.

Comparing the size of Mothra and my hand – she is still growing 🌻

The colorful protuberances with black spikes are thought to mimic either a poisonous plant or animal and are a defense against predators. Like most caterpillars, the Cecropia moth caterpillar has five pairs of prolegs. The green prolegs are blue at the base with a row of microscopic hooks, or crochets, that enable walking and clinging.

Although the Cecropia Moth has the largest wingspan of any moth found in North America, its caterpillar is not the largest caterpillar. That honor goes to the caterpillar of the Royal Walnut Moth, also called Regal Moth, which in its caterpillar stage is called the Hickory Horned Devil.

Thank you again to friend Christine for the Cecropia Moth eggs. The eggs that she gave me are the offspring of the male Cecropia Moth that she is holding in the photo above.

Beautiful caterpillar of the beautiful Cecropia moth, North America's largest species of Lepidoptera

Don’t you love the colors of the third stage, or instar, of the Cecropia Moth caterpillar? Only about an inch and a half long in the photo, in the final fifth instar, before it pupates into a cocoon, the caterpillar will be as large as a large man’s thumb.

This is an evolutionary form of mimicry against predation by birds. Cecropia Moth caterpillars eat not only the foliage of American White Birch trees, but also other species of birch trees, apple, ash, beech, elm, lilac, maple, poplar, Prunus and Ribes species, white oak, and willow.

Thank you so much again to my friend Christine for the gift of the Cecropia moth eggs. 

Cecropia Moth Caterpillars and Shout Out to Gloucester Water Chief Engineer Larry Durkin and Senator Bruce Tarr

Cecropia Moth caterpillars copyright Kim SmithOur caterpillars of the beautiful Cecropia Moth, given by friend Christine, are in their second instar and growing rapidly on a steady diet of birch leaves. The Cecropia Moth is just one of the many reasons why we would never spray trees with pesticides and herbicides.

A HUGE SHOUT OUT to Gloucester’s drinking water chief engineer Larry Durkin and to Senator Bruce Tarr for working hard to keep glyphosate (Monsanto’s Roundup) out of our water supply. Glyphosate is a known carcinogen and extremely bad news for bees, butterflies, and all pollinators. Durkin is pressing Keolis, the company that operates the MBTA commuter rail track service, to cut its use of glyphosate along the track adjacent to the Babson Reservoir and to manually cut back the growth.  Read the full story here in the Gloucester Times.

Polyphemus Moths Mating

Polyphemus Moths Mating copyright Kim SmithPolyphmeus Moth update ~ The evening of the day that Jane’s female Polyphemus Moth emerged, she found two males outside the net enclosure eager to get in and meet the female. Amazingly, the wild males had found the captive female by the pheromones that she began to release soon after emerging from her cocoon. The purpose of the male’s large and feathery antennae is to detect the females pheromones. This is the natural biological world functioning as it should, but I still find it so interesting and extraordinary!

Jane opened the door for the males and in the morning, discovered the female and one of the males mating. They stay coupled together for about a day. The female will begin to oviposit eggs almost immediately.

Polyphemus Moth cocoon. The hole at the end is from where the moth emerged. The cocoon is constructed of leaves wrapped around a cushion of spun silk. In the photo you can see the leaf structure and silk.

Resplendent Newly Emerged Luna Moths

Male Female Luna Moth dorsal Copyright Kim Smith copyConsidered by many to be North America’s most beautiful insect, a newly emerged Luna Moth will melt the heart of even the most vehement of insectophobes. These male and female pristine beauties were photographed at new friend Jane’s lush garden in Gloucester. Jane, along with her friend Christine (who we met last week), intend to repopulate Cape Ann with members of our native Giant Silkmoth Family. See story here.

In the photo above, the female is in the lower right. You can easily tell the difference because the male has much fuller antennae–all the better to detect the female’s pheromones.

Female Luna Moth Copyright Kim SmithHer abdomen is swollen with eggs. A female Luna Moth will oviposit between 400 to 600 eggs, more during warm weather.

Not quite as large as the Cecropia Moth, nonetheless its wings span nearly four and a half inches. You are most likely to see Luna Moths flying during evening hours and the caterpillars munching on birch leaves, one of their favorite food plants in our region. The adult moths only live for a week and during that time are unable to eat (they emerge without mouthparts). The mature Luna Moth’s sole purpose is to mate and deposit eggs of the next generation.

Many thanks to Christine and Jane for sharing their passion for the gorgeous Giant Silkmoths!

This short film of a Luna Moth in flight was made after finding a Luna Moth at Willowdale Estate. I returned home with the moth and as evening approached it began to quiver and vibrate in preparation for flight. I had been listening to Ave Maria and it was playing in the background so I left it in the video and think the music perfect for this most stunning of creatures.
