Spined Micrathena

If you’ve ever walked through a spider web in the woods, chances are it was a micrathena’s web. As an added “bonus” they tend to make their webs at face level.

spined micrathena_09c

This is a small species, about 1/2 inch long, with a chunky abdomen with ten spines on it. The abdomen can vary in color, but is usually it is whitish, yellow, or brownish-black. Only female Spined Micrathenas build webs. Male are about half the size of females. They only have a couple of spines and a much flatter abdomen.

To trap prey, this spider builgs her web between shrubs or small trees, three to seven feet off the ground. Insects that try to fly in between the trees don’t see the web and get caught.

spined micrathena 009c

The female Spined Micrathena eats her web each evening and constructs a new web the following morning. I had one that is living in my front yard this past Summer, and she built each web in the same spot.

spined micrathena_3686

In the daytime the spider hangs out in the center of her web, with her head pointing down. As soon as she feels the vibrations of prey trapped in her web, she runs to bite it. These spiders are slow and clums and many insects escape before they are caught.

Male Spined Micrathenas don’t build webs, though they do weave a “mating thread.” The male finds a female’s web, and weaves his mating thread onto her web. When he’s ready, he quickly runs out and mates with her. Males often do not survive the encounter.

This is a small, yet very cool spider that I usually enjoy coming across (unless I walk face-first into one of their webs).

Dwarf American Toad

dwarf american toad_5530

I love toads and finding a new type while on a herping adventure is always a thrill. In October, while visiting southern Illinois, I came across a couple of examples of this little gem.

dwarf american toad_3248

As the name implies, the Dwarf American Toad is rather small – about 1-1/2 to 2-1/2 inches. These creatures are often brick red in color without any distinct pattern. The bumps behind their eyes are called paratoid glands; they produce a foul-smelling, toxic chemical. This keeps some predators from trying to eat these toads.

dwarf american toad_3252

These amphibians are found in most of the south central region of the United States. They live in habitats ranging from forests, open fields and pastures and even residential areas – as long as the habitat contains leaf litter, sandy or loamy soil for burrowing, moist hiding places, and an abundance of food.

dwarf american toad_3253

Toads are most often seen and heard in the Spring when they are breeding. They are also seen frequently in the Fall when they look for new places to live and hibernate. They are mostly active at night.

dwarf american toad_3254

Dwarf American Toad are predators and they eat a lot. Insects, spiders, earthworms, snails, and slugs make up most of their diet, but they will eat just about anything that fits in their mouths. They catch food by lashing out with their sticky tongues to grab prey. If the prey is large, they will use their arms to stuff it into their mouths.

dwarf american toad_3258

This amphibian’s Latin subspecies name, charlesmithi is in honor of its discoverer, Charles Clinton Smith – an American naturalist and educator in the early 1900s.

Virginia Pine

Virginia Pine_7783

Virginia Pine are small to medium-sized pine trees, growing up to 60 feet. They have long, spreading branches and reddish brown bark.

Virginia Pine_7670

Their pine cones are small and oval-shaped, up to two-and-a-half inches long; small seeds come from the cones. Their short yellow-green needles are paired and are often twisted.

Virginia Pine_7671

I have these trees growing in my front and back yard – they don’t fare well in forests, because thay have shallow roots and must have plenty of sun to survive. They eventually get pushed out by larger trees. Because of this, Virginia Pines are good pioneer plants, meaning they are some of the first trees to take over a field.

Virginia Pine_7767

Virginia Pine seeds are consumed by many birds and small mammals. These animals help spread the seeds by carrying them to new places. These trees are a favorite of woodpeckers, because of the soft wood in older trees.

Another enjoyable aspect of this tree is its easy-to-remember scientific name – Pinus virginiana.

Central Stoneroller

central stoneroller_7518

After spending a bit of time exploring this creek, a caught a cool fish. The common name for this fish, “central stoneroller,” comes from the behavior of the male excavating a nest by moving gravel with its nose.

central stoneroller_640

These are moderately stout, brownish colored minnows with small eyes and short, rounded fins. The snout is bluntly rounded and projects beyond their nearly horizontal mouth. Their mouth is white.

central stoneroller_5754

The Central Stoneroller is found throughout Ohio in moderate to high gradient streams with sand to gravel bottoms. They prefer riffle areas where riffles and pools alternate in rapid succession. Adults range in length from 3 to 5 inches, but they can reach 7 inches and males are generally larger than females.

Central Stoneroller_2061

They feed by scraping algae and and other organic matter from rocks and logs with the spade-like extension of their lower jaw. It is classified as a grazing minnow in its feeding behavior, and large schools of these fish often feed together.

Central Stoneroller_1929

The Central Stoneroller belongs to the Minnow and Carp family of fish. It goes by several other names: Dough Belly, Racehorse Chub, Rotgut Minnow, Steel-backed Chub, Stone Luger, Stoneroller, and Tallow-mouth Minnow.

Red Squirrel

red squirrel 7313
The Red Squirrel is a small squirrel (compared to the Gray Squirrel and Fox Squirrel) with reddish to reddish-gray fur on top and a white underside. It has white around its eyes. Its tail is not as long or bushy as the tail of other tree squirrels. In the Summer, the red squirrel may have a black stripe on its sides.

red squirrel 0988

Its curved front claws and powerful hind legs make it a very good climber and jumper. The Red Squirrel can reside in pine, deciduous (trees with leaves) and mixed pine-deciduous forests.

red squirrel 9574

This mammal eats a wide variety of foods including insects, seeds, bark, nuts, fruits, mushrooms and pine cones. In the Autumn it will remove green pine cones from trees and store them in the ground. It also stores nuts and seeds in piles or under logs, at the base of trees and underground.

red squirrel 7276

It doesn’t always find or eat all of the seeds and nuts it has stored. Because of this, the Red Squirrel plays an important role in spreading seeds throughout the forest. This animal also drinks tree sap from maple trees. It bites a tree until the sap flows out and returns to drink it after the water in the sap has evaporated.

red squirrel 1421

The Red Squirrel is very vocal and chatters, growls and screeches. You can usually hear more of these forest creatures than you can see. Its bright eyes, perky disposition and chattering, rattling call add to the “personality” of the forest.

Northern Map Turtle

map turtle_4668

Walking along the Ohio & Erie Canal Towpath this Summer I encountered a turtle that I had never seen in the wild before. Its Latin species name is geographica and both this and its common name “map turtle,” refer to the markings on the skin and shell.

map turtle_4658

Part of the difficulty in finding this turtle is that it prefers to live in large rivers and is very wary, diving into the water at the slightest disturbance. It prefers large bodies of water and areas with fallen trees and other debris for basking. These turtles are more often found in rivers than in lakes or ponds.

map turtle_4649

Northern Map Turtles are more carnivorous than most other water turtles. Adult females have wide heads and broad, flat crushing surfaces in their mouths which they use to feed on molluscs, their primary prey, as well as insects and crayfish.

map turtle_4612

It is not unusual to see these turtles walking around under the ice, for they are among the very last turtles to go into hibernation – if they go at all – and among the earliest to reappear in spring.

map turtle_4631

The female of this species attains a shell length of about 10 inches, while the male’s seldom exceeds five inches. These reptiles are found throughout the eastern half of the USA and northward into southern Canada. In addition to being called Map Turtles, they are also known as Sawback Turtles. Whatever you call it, it was awesome to see this reptile in the wild!

Bald-faced Hornet

Bald-faced Hornet_6996

It may be December, but a walk through the woods can still yield insect life, if you are willing to turn a few logs. Earlier in the week I found this hardy creature.

Bald-faced Hornet_4070

This insect gets the first part of its name from the ivory-white markings on the face. Despite the second part of its name, the Bald-faced Hornet is not a “true” hornet, rather it is a a type of yellowjacket.

Bald-faced Hornet_4077

Fertilized queens like this one overwinter in protected places such as in hollow trees, rock piles, under bark and in the walls and attics of buildings.

Bald-faced Hornet_4069

In springtime, she collects cellulose from rotting wood by chewing it. She then adds her saliva and creates a paste to make a papery material with which to construct a football shaped, grey paper-like nest.

Bald-faced Hornet 057

The queen creates a few brood cells within the nest and deposits eggs in them and feeds the larvae when they hatch. This Bald-faced Hornet built her nest on my deck in the summer.

Bald-faced Hornet 119

Though they don’t have much of a “fan base,” Bald-faced Hornets are considered a beneficial insect because they reduce populations of unwanted insects (including other yellowjackets) and pollinate flowers when they are searching for nectar…and I think they are a cool creature to come across on a December hike.

Yellow-bellied Water Snake

yellowbelly_2989

This is the most commonly encountered water snake on my recent trip to southern Illinois. It is named for its yellow belly. Its coloration is mainly gray or greenish with little or no pattern.

yellowb2

Like other species of water snakes, Yellow-bellied Water Snakes give birth to live offspring. The young are pale gray, with a pinkish cast on the sides, with squarish, alternating blotches. These markings begin to disappear during their second year.

yellowbelly_3859

Yellow-bellied Water Snakes are a species that is found in swamps, lakes and ponds – where it can be seen basking on overhanging branches or logs in the water.

yellowbelly20030

Water snakes are not constrictors; they simply overpower their food. This species has a preference for frogs, toads, tadpoles and salamanders – but it also eats fish and crayfish.

yellowbelly_1586

The Yellow-bellied Water Snake is less aquatic than the other water snakes. During hot, humid weather, it will travel considerable distances away from water. It is unique among water snakes in that it often flees onto land, instead of diving underwater when approached like most species of water snakes.

yellowBell

I enjoy encountering these reptiles, which are quite different looking than the Northern Water Snakes I commonly see in my home state of Ohio.

Great Egret

great egret_5663

While visiting southern Illinois and searching for reptiles and amphibians along the banks of the Big Muddy River, I came across a number of these majestic birds.

great egret_5614

The Great Egret is a member of the heron family. This bird is the symbol of the National Audubon Society, which was formed to stop the slaughter of herons for their showy plumes. It is our second largest heron; only the Great Blue Heron (shown in photo above with Great Egrets) is bigger.

great egret_5654

In the early 20th century, they were almost hunted into extinction for their long, attractive feathers that were commonly used as decoration for ladies hats, but their numbers have increased over most of its range and they continue to expand their territories. During the breeding season, both males and females grow long lacy, delicate and flowing plumes on their backs that curl over their tails.

great egret_5619

With a wingspread of 55 inches, their wings are longer and wider than most other white herons. During the day, they forage alone or in mixed flocks, catching fish by standing motionless in the water. The neck has a characteristic kinked S-curve. When prey comes within striking distance, they spear it with their long, sharp bill. The largest part of their diet consists of fish, frogs and crayfish.

great egret_5646

A group of egrets has many collective nouns, including a “congregation,” “heronry,” “RSVP,” “skewer,” and “wedge” of egrets.

Bird’s Nest Fungus

Bird's Nest Fungus_3837

While I was doing a little yard work this week, I came across something tiny, yet awesome. They look like tiny cups filled with a few dark seeds or, as their name implies, tiny bird’s nests.

Bird's Nest Fungus_3834

There are several different species of this Bird’s Nest Fungi in northeast Ohio, but they all belong to the same family, Nidulariaceae. The scientific name is derived from the Latin word “nidus,” meaning nest.

Bird's Nest Fungus_3835

Bird’s Nest Fungi feeds on decomposing organic matter and is often seen growing on decaying wood and in soil enriched with wood chips or bark mulch. These were living where a tree had been cut down almost a year ago and only its ground up stump remained. Like so many fungi, most of the organism is hidden from view. The fungus spends most of its life as a series of nearly invisible threads among strands of decaying wood. The threads secrete enzymes which have the ability to digest wood.

Bird's Nest Fungus_3341

The cuplike nests which are visible are fruiting bodies which contain spore-filled eggs. The nests act as “splash-cups.” When a raindrop hits one at the right angle, the walls are shaped so the eggs are expelled to as much as a yard away from the cup. This unique little fungus is an evolutionary masterpiece and it was very cool to see it for the first time ever in my backyard.
