Predators – Tendrils

Northern Walkingstick

It wasn’t too long ago that I became aware there was an insect called a “walkingstick.” A creature that I would have marveled at as a child. During my growing up years I spent loads of time in the woods, but never did I see such a thing. I’m delighted now that I know about these critters.

This Northern Walkingstick (Diapheromera fermorata) is native to North America. Its range in the US extends from the Atlantic coast, Maine to Florida, west to New Mexico and north to North Dakota. In Canada it is found in Alberta, Manitoba, Ontario and Québec. Northern Walkingsticks have built-in eye protection that acts to shield them from excessive sunlight.

They have an incredible camouflage, looking like a twig, and will keep their legs close to their body and remain perfectly still when they sense predators, such as American Robins or Crows are nearby. Sometimes a predator only gets away with a leg. These clever insects often are able to regenerate that lost leg. Northern Walkingsticks are found in deciduous woods and forests. They seek out oaks and hazelnuts, skeletonizing their leaves.

Eastern Fence Lizard

A cute little creature that I see climbing on the cinder block foundation of my cabin on occasion. An Eastern Fence Lizard (Sceloporus undulatus). With golden eyes that stare back at me wondering what I am.

Fence Lizards grow to be between four, and seven and a quarter inches long. Usually females are gradations of gray and males are various shades of brown, both with keeled scales. Their native range is from New York to northern Florida west to Ohio and Arkansas.

Predators of Eastern Fence lizards include snakes, birds, cats, and other reptiles. When confronted they will seek a tree, running to the opposite side circling to stay out of sight.

Eastern Fence Lizards dine on invertebrates including beetles, ants, moths, grasshoppers, spiders, and stink bugs. Oh little lizard friends, please eat lots of those Brown Marmorated Stink Bugs!

Eastern Tiger Swallowtail

My first sighting this season was yesterday. The state insect of Virginia, the Eastern Tiger Swallowtail Butterfly (Papilio glaucus). Native to eastern North America. The butterfly I saw yesterday had just emerged from its chrysalis. Brand new.

This is what a chrysalis looks like. Though NOT an Eastern Tiger Swallowtail chrysalis, it looks to a large extent like one. One major difference would be more rich brown and less bright yellow. The shape is basically the same. This is a Pipevine Swallowtail (Battus philenor) chrysalis.

In the autumn an Eastern Tiger Swallowtail caterpillar will form itself into a chrysalis. NOT a cocoon but a chrysalis. Cocoons are used by moths. Chrysalises are used by butterflies. In ten to twenty days or over the winter the caterpillar makes incredible changes. As if by magic it will become a butterfly — to live just six to fourteen days.

Mainly males, after emerging, often will gather at puddles to take in sodium and minerals which tend to be lacking in the adult’s diet and are necessities for reproduction and flight. This is called “puddling.”

Speaking of reproduction, Eastern Tiger Swallowtails generally have two broods each year. Females lay their eggs on such trees as Tulip Poplar (Liriodendron tulipifera) and Wild Black Cherry (Prunus serotina). Those eggs will hatch in four to ten days as caterpillars. The earliest stage of the caterpillar looks just like bird droppings. The mature caterpillar is green, with eye spots, and a pale “neck ring.” Further to the front is a little purply-pink head.

Although most females look nearly like males, mostly yellow and black, there is a black form of the female Eastern Tiger Swallowtail. This is a method of protection. The black form is a mimic of the Pipevine Swallowtail (Battus philenor) which has a disagreeable taste. Predators have learned to avoid both the Pipevine Swallowtail and the Eastern Tiger Swallowtail’s black form. The portion of females with this coloring is more common in areas where there are more Pipevine Swallowtails.

The caterpillar becomes a chrysalis which becomes a dazzling butterfly. And so it goes. On and on.

Eyed Click Beetle

A goal of my hike this morning was to find a cover shot for my Facebook timeline. I was collecting images of tree bark, lichen, and beautiful mosses, all possible candidates. At a mature sassafras tree, as I worked around some poison ivy vines, I came upon a surprise: two BIG eyes looking back at me. Turns out, it was an Eyed Click Beetle, Alaus oculatus, one mighty funny looking creature.

This beetle is pretty large, almost 2 inches long. He has enormous fake eyespots on his back, which are a means of protection. The eyespots and the pattern on his back are composed of scales, much like on the wings of butterflies. These eyespots are to startle predators, perhaps making them think that they have run into a critter much larger than the Eyed Click Beetle actually is. The Eyed Click Beetle’s real eyes, one on either side of its small head, are located at the base of its saw-toothed antennae.

The name “click beetle” comes from another means of protection. When a click beetle finds himself on his back, or when being held by a predator, the beetle will create an unnerving snapping or clicking sound by bending his head backwards and suddenly snapping it straight. This action creates the sound, and sends the click beetle several inches into the air. That is something that sure would shock me, if I wasn’t expecting it. The catapulting can put the beetle right side up, but if it doesn’t, he’ll try again until he is successful.

The larvae of most click beetles are called wireworms. Some of them are serious pests that feed on the roots of crops including potatoes, strawberries, corn and wheat, and also the roots of lawns. These destructive wireworms find their food by following the carbon dioxide produced by their foodplants in the soil. They often use preexisting tunnels to travel through the soil to get to their food. However, the larvae of the Eyed Click Beetle are well behaved predators, that prefer to eat caterpillars and the larvae of wood boring beetles and flies. The Eyed Click Beetle lives in the larva form (as a wireworm) for two to five years and spends that time underground or in rotting logs.

I’m hoping I’ll find another Eyed Click Beetle as I hike up my mountain tomorrow. Perhaps I can get him to do a catapult for me.

*Bloggers note:

This blog was originally posted in a slightly different form, in the summer of 2013. At that time, I was participating in a group blog (BeautifulWildlifeGarden.com), with smart, dear, nature loving friends. Unfortunately that website has gone belly up. I am resurrecting this post so that those of you who have not seen it, can read more of my ramblings.

My Winter Birds

Perhaps these are my pets, the birds that come to my feeders. Wild birds that give me comfort just by being there. The bird you see in the picture, above, is a winter bird in my area (the Blue Ridge Mountains of Virginia), a White-throated Sparrow, Zonotrichia albicollis. He has a sweet song that is easy to remember, using the mnemonic, “Poor Sam Peabody, Peabody, Peabody.”

I know that autumn will not last much longer, when I see these little birds, rustling around in the leaves on the forest floor. I have to look very closely to see them. Their feathers provide a great camouflage against the dry, brown, fallen leaves.

I must wait for the bears to retire for their winter slumber, before I put out the feeders for the cold months of the year. Otherwise I am likely to need to purchase a new feeder. Believe it or not, the bears do like bird seed too, and will carry a feeder off, or just totally destroy one with ease.

The bear, above, came out of his den, unannounced on January 17th, to cart off one of my feeders. He chose a new model that was designed to keep squirrels out. Needless to say, bird feeder designers don’t aim to keep bears out of the seeds. I suppose that would be an impossible task. If I know that bears are roaming, I don’t put out feeders.

I’m hoping Mr. Bear, is now back in his den. Hoping that the cold will keep him all snug and warm, and away from the bird feeders for while longer. Not only do I enjoy simply watching the birds and their antics, I depend on the feeders to bring them within easy shutter range, so that I can get pictures of my winter pets.

Another bird of winter, is the Dark-eyed Junco, Junco hyemalis. Most of them summer in the far north, some going into the Arctic. A few however, do stay in this general area year ’round. I have seen some summering in the Shenandoah National Park, which is just a short distance from my cabin. Here at my feeders though, it is only the migrating Dark-eyed Junco, that I see.

I speak of the wild birds as my pets. I don’t have any “all the time” pets living with me. A frequent visitor, though, is my son’s and daughter-in-law’s cat, Betelgeuse.

That’s Betelgeuse, in the picture above. She’s a rescue, Maine Coon cat. She is a predator. For her own safety and health, and for the sake of my wild pets, she is an indoor pet. I hope your cat is an indoor cat as well, for the sake of my wild pets.

Gray Fox

Until I moved to my cabin in the Blue Ridge Mountains, if I had any thoughts of a fox, it was a Red Fox, Vulpes vulpes, with a rusty red coat, black legs and white tipped tail. I quickly learned that there is another fox that lives up here at 1800 feet. Slightly smaller than a Red Fox, the Gray Fox, Urocyon cinereoargenteus, generally weighs between 8 and 15 pounds, and in length is between 30 and 44 inches, with about one third of that being its tail. The male Gray Fox is usually larger than the female.

The coloring of the Gray Fox is salt and peppery on his back. His sides, back of his head and legs are rusty red, reminiscent of the Red Fox. His long, lush tail is the same salt and pepper as his back, with a stripe of black on top. Unlike the Red Fox, the Gray Fox has no snow white tip on his tail but a tip of coal black. A new born kit is generally dark brown.

The Gray Fox has an elegant, long, very strong neck. He is equipped with hooked claws, which allows him to easily climb trees, to escape predators or to forage for fruit. To get down from the tree, he will bound from branch to branch, or comes down backward, as a house cat would do.

The Gray Fox is an omnivore, dining on cottontails, mice, voles, shrews, insects, as well as birds. But I became aware of the Gray Fox as he would come to eat the sunflower seeds that I put out for the birds. Yes, like Black Bears, Gray Fox also eat seeds and berries! They also eat roots and tubers. If their food supply is plentiful, they will cache their extras, digging a hole with their forepaws and burying the extras.

The Gray Fox is monogamous and has a gestation period of 53 days with the litter size ranging from 1 to 7 kits. The life span of a Gray Fox is from 6 to 8 years, both in the wild and in captivity. Predators of the Gray Fox are Bobcats, Great Horned Owls, Coyotes and Golden Eagles. Along with escaping by climbing trees, they will hide in brush piles or other cover to avoid capture.

The Gray Fox prefers the isolation of deep woods, while the Red Fox is more adaptable and can deal with changes that humans present to their territory. The Gray Fox sounds like me in that respect. I enjoy my home far from the maddening crowd!

Along with so many other critters that live in these woods around my home, the Gray Fox is a welcome sight, and one that delights me whenever one or two stop by for a visit.
