Insects – Page 3

Black Walnut Bark

So many trees out there! Summer provides us with leaves to look at to recognize species, often right away. When winter arrives we’re left with very little hint as to what species of tree we might be looking at. Along with limb character, the tips and buds on branches, and the look of leaf scars, there is also the bark of the tree. The tree above is a Black Walnut (Juglans nigra).

Black Walnut is a tree that is plentiful here in the Blue Ridge Mountains, giving me an opportunity to really get acquainted with all its traits. In the image above a White-breasted Nuthatch is checking out the bark of a Black Walnut tree by going down the trunk in its amusing way, going down head-first. Check out the pattern that the bark has presented to you.

From time to time the bark of the Black Walnut will remind me of a work of macrame or some other fiber artwork. Weaving maybe?

In this photo you’ll see a couple perfectly round holes in the Black Walnut bark. These are created by a Yellow-bellied Sapsucker. The Sapsucker will hammer out a series of holes, drink the sap and eat the insects that get trapped in the sticky liquid.

The bark of Black Walnut, is communicating to you. Speaking to you in its limited winter way. Trying to tell you its identity.

White-breasted Nuthatch

Yesterday’s post was about an irruptive visitor. The tiny Red-breasted Nuthatch (Sitta canadensis) who shows up in the woods of the Blue Ridge Mountains of central Virginia, if its usual seed supply is less than optimal. But there’s another Nuthatch that lives here all year long. The White-breasted Nuthatch (Sitta carolinensis).

It is fun to find this Nuthatch searching for insects in crevices of tree bark. It goes up, down, and when heading DOWN the tree trunk it goes head first. It will eat insects, seeds, nuts, suet and peanut butter. A nice customer to have at the feeder.

I love to hear the White-breasted Nuthatch making its wonderful songs and calls. Announcing itself with a series of soft chuckles. Or on other occasions it may sound like the beep of a small tin toy car.

A little bird, larger than the Red-breasted Nuthatch, smaller than a Tufted Titmouse. Fun to find whether at the feeder or as I’m wandering the mountain.

European Hornet

Here in the mountains fermenting persimmons have drawn many butterflies as well as European Hornets, Vespa crabro. These large insects have been in North America since the 1800s. When I say “large” I mean 1.25” – LARGE. They dine on insects such as bees, flies, and grasshoppers. As summer begins to wind down and the populations of their insect meals dwindle they concentrate on sweets such as rotting fruit and hummingbird syrup. And they aren’t happy to share – often chasing the hummingbirds away.

Yellow-rumped Warbler

Yellow-rumped Warblers, Setophaga coronata, have to come to visit for the winter. They’re also affectionately referred to as Butter Butts.

When insects are available, that’s their meal of choice but here, in the cold months, they will settle for goldenrod seeds, and the berries of juniper, poison ivy, poison oak, greenbrier, grapes, Virginia creeper and dogwood.

Some people are able to entice them to feeders with sunflower seeds, raisins, peanut butter, and suet but I’m not one of the lucky ones. That’s okay! They seem to like it here anyway. AND they do seem to enjoy the bird bath that I keep ice free during the winter.

GOOD Mosquito?

Legs covered in blue and purple sparkles with a gilded body, much larger than mosquitoes that we usually notice, the Elephant Mosquito, Toxorhynchites rutilus, is one mosquito that we should encourage.

The largest mosquito in North America, from tip to tip (of its legs) this mosquito measures one inch, and the adult female has a wing span of half an inch. That large size, and a proboscis that resembles an elephant’s trunk, gives this mosquito its common name. That proboscis is used for the gathering nectar from flowers.

Here is the REALLY good part (1), the Elephant Mosquito does not hunt humans down to get a blood meal. They won’t bite us as they cruise the gardens looking for sources of nectar. They won’t bite as they roam the neighborhood hunting for plant sap, honeydew, or juices from rotting fruit, which they also eat.

And REALLY good part (2), the larvae of Elephant Mosquitoes eat other mosquito larvae!

Wow! Include this insect on my list of best friends!

Chicory

It has a color that pulls me in, bright medium blue, with a smidgeon of purple thrown in. It tugs at my heartstrings. Chicory, Cichorium intybus, is native to Europe but has become naturalized in many parts of North America, and is part of the roadside landscape here in central Virginia.

Chicory is a tough plant, sending its deep taproot into hard packed soil where other plants might have a difficult time. It blooms from June into October, producing just a few buds at a time on each plant. Each bud blooms for just one day.

The leaves are edible and are most tasty in early summer and in the autumn. The leaves in mid-summer tend to be bitter. The roots, roasted and ground, are used for an addition to coffee, or as a coffee substitute. Also, in beer brewing, the ground and roasted roots are occasionally added in the making of stouts and Belgian-style ales.

Its pollen and nectar entices insects, including bees, flies and butterflies. Chicory seeds, leaves and stems invite small mammals to come by for a meal or snack. And for those who love a bouquet of wildflowers, keep in mind that these flowers only last a day, and those stems are mighty rugged, requiring more than just a quick snap of the shoot.

Rather than taking some home, I will depend on my photographs and thoughts of that gorgeous purply-blue.

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.

Fruit at the Cabin

In front of my cabin right now, there is a constant buzz . There are loads of trees and bushes involved in the sound, three good sized trees, planted soon after our cabin was built, many years ago – pear, MacIntosh apple, and Monmorency cherry, and a good number of blueberry bushes planted at about the same time as the fruit trees. Plus there are several wild cherry trees contributing to the buzz, at the edge of the woods.

As you might imagine, the sound is not exactly being generated by the trees and bushes themselves, but by the critters that are enjoying the nectar, like the Hummingbird Hawk-moth, Hemaris thysbe, pictured above, at the apple tree.

There are loads of bees and wasps. This bee is sipping nectar at one of the blueberry bushes.

The most plentiful species buzzing about is a large number of Eastern Tiger Swallowtail, Papilio glaucus. They give action to the scene with their constant motion and larger size. The two images, above, are both Eastern Tiger Swallowtails. The top image is a light morph female. The image immediately above is a male.

This, above, is also an Eastern Tiger Swallowtail. It is a dark morph female. The dark morph female is mimicking the color and pattern of the Pipevine Swallowtail, Battus philenor. There is a measure of protection using this coloring and pattern, since Pipevine Swallowtails are poisonous and predators will be less likely to eat the mimic.

This visitor, a bit frayed, is one of my favorite butterflies, a Zebra Swallowtail, Protographium marcellus. If this butterfly were newly emerged from its chrysalis, it would have two swordlike tails and the faded coral spots, that you see here, would be a brilliant crimson.

Another butterfly buzzing about is the Silver-spotted Skipper, Epargyreus clarus, one of our largest skippers. Interesting: it is said that the Silver-spotted Skipper will not seek the nectar of flowers that are yellow. I’ll have to watch the yellow flowers on the mountain, and see! This skipper is quite common in the area.

All this action, sipping of nectar, brings on pollination of the blooms. Soon there will be apples, pears, cherries, and blueberries as a result, enough to keep me busy for a while, like the pollinators that are busy right now!

Red-spotted Newt

I have an adult Red-spotted Newt, Notophthalmus viridescens, in my small pond. Doing research, and learning about this newt has been a fun journey.

A type of salamander, they start out their life in a pond, marsh, stream or small lake, as an egg mass that resembles a big wad of cotton, attached to a piece of underwater vegetation.

The Red-spotted Newt, lays her eggs, one at a time, and the eggs, often numbering a few hundred, will hatch in a month or two, depending on the water temperature. When the eggs hatch they become larvae with feathery gills and a coloring much like the adult Red-spotted Newt.

**Juvenile stage of the Red-spotted Newt, land based, Red Eft**

The larvae live in their watery environment for 2 to 5 months eating aquatic insects and small snails.

At the end of summer, larvae will leave the water, shedding their gills, developing sac-like lungs, and begin another stage in their lives, as Red Efts, remarkably beautiful orange beings with brighter orange spots, surrounded with black circles.

I enjoy finding Red Efts, while I’m out in the woods. They are slow moving critters, appearing to be willing models for my photography.

They spend as many as 4 years as terrestrial creatures. During this stage the Red Efts will hibernate during the winter under a log or rock. During the summer in dry weather they may seek shelter under those same logs or rocks to keep their skin moist, coming out during rainy weather.

**An adult Red-spotted Newt in his underwater world**

For the next couple years, the Red Eft will become darker, and develop a longer, blade-like tail. He will find a body of water to enter, where he will live for the rest of his life as an aquatic adult. In this stage he will eat insects, frog and fish eggs, crustaceans, and worms.

Notice the long tail of the Red-spotted Newt in his underwater world — **Notice the long tail of the adult Red-spotted Newt in my pond**

Red-spotted Newts can live to be 12 to 15 years old. Quite a long life for a critter so small, generally growing as an adult to 5 inches long.

It took me a few years, first to find that I had a newt in my pond. And then to have the information click in my brain, to realize that this newt, and the Red Eft, and all the cottony masses of eggs were all the same species.

Fun finds in the forest!

Sap is Flowing

In the past three days I have been entertained by a visitor that I have not seen for more than two years. I don’t really know if this visitor is actually one that I saw during the bitterest of late January and early February of 2014, but she is quite fun to watch whether new to my woods or not. I can see her out my kitchen window. She is a Yellow-bellied Sapsucker, Sphyrapicus various.

Back in the winter of 2014, a family of Yellow-bellied Sapsuckers showed up at the “watering hole” adjacent to the woods, and just outside my kitchen window. Female, male and juvenile. It was so cold that I was concerned for them. The only thing they seemed to be doing was enjoying the warm water that I had provided, and shivering. Particularly the female. In the picture above, by the way, is the male. Notice his stronger coloring, and the crimson patch at this throat, compared to the first picture, my current visitor, a female. They stayed around for a few days, during those extreme days of 2014, and then I never saw any of this species of woodpecker again, until just a few days ago.

The female that has appeared at the suet feeder has declared this suet to be hers and hers alone.

She takes her time feeding at the suet and takes a break, clinging to the little Dogwood trunk just a few feet away, with her sharply clawed toes. There have been Chickadees, Tufted Titmice, and Downy Woodpeckers who are regulars at the suet feeder. Now, if the Yellow-bellied Sapsucker sees someone that she considers a violator of her space she immediately throws her body at the intruder. This has gone on for three solid days, every moment that the suet feeder has been out there, in daylight. I don’t know where she goes as the sun goes down, but she must trust that nobody is going to eat her suet.

This behavior has me curious and I’ve gone to an amazing reference “book”, the internet. I find that Yellow-bellied Sapsuckers drill holes into trees that create sap flows, called sapwells. Sapwells provide the birds with sap which they lap up with their brush-tipped tongues, a path to the tree’s cambium which they eat, and the sap traps insects which they also eat.

The information about the sapwells is not new to me. Up in the woods there are trees that have lines of holes. These are sapwells created by the Yellow-bellied Sapsuckers. Even in the trees immediately around my cabin, I don’t have concern about the woodpeckers harming my trees. Seldom is serious harm done.

I do find a bit of information that might apply. These Sapsuckers tend to watch over and protect their sapwells. This has me wondering. Could she have tapped into the little Dogwood? I go out and sure enough, I find a sapwell! And within a short time, she is working on another Dogwood just a short distance away. From my perch at the kitchen window I can see telltale moisture around the area where she has been working.

Nature is always prodding me to dig to get more information. Dig to learn more. I love Mother Nature.
