Southern Leopard Frog

swamp_9249

This is one of the most conspicuous herps that I see on my visits to southern Illinois. At night they are often out and about and seen crossing roads. In the daytime I’ve encountered them in a range of habitats, including deep in the woods and high up in limestone bluffs.

It is also one of the most variable amphibians in the area in regards to appearance. It can be green or brown in color with varying amounts of spots – and sometimes no spots at all.

Although Southern Leopard Frogs are often found close to water, they are more terrestrial than other frogs in their genus and can stray far from water. They are active both by day and night and can be seen in large numbers on rainy nights.

They are powerful, agile jumpers and may flee away from water rather than toward it. When being pursued, they leap in haphazard, zigzag patterns that make they very difficult to successfully pursue and capture.

Southern Leopard Frogs search for food mainly on land. Insects make up the majority of their diet, but they also feed on spiders, pillbugs and worms.

Despite is being quite common, I always enjoy coming across this beautiful amphibian – no two are alike!

European Hornet

Snake Road_9975

While searching for snakes in southern Illinois this month, I flipped a rock and under it was this large (over an inch long) insect. This the only true hornet found in North America, having been introduced by European settlers in the 1800′s.

European Hornet_3938

Most examples I’ve seen have been in the Autumn and are probably females (mated queens) looking for a place to overwinter before starting a new colony the following Spring. Only overwintering queens survive in protected sites such as under loose bark, in tree cavities, under rocks and in buildings. All other colony members produced in the current year perish.

European Hornet 026

I have seen European Hornets in my home state of Ohio as well. They are mainly carnivorous and hunt insects such as beetles, caterpillars, moths, dragonflies and crickets. They also feed on fallen fruit and other sources of sugary food. I saw this one at a hummingbird feeder. These insects have been observed stealing prey from spiders, which can be classified as an example of kleptoparasitism.

European Hornet_5489

Though they probably have a painful sting, they usually aren’t particularly defensive when not protecting their nest. This woodland species constructs its large paper hive in natural cavities, especially in hollow trees. The nests typically have 200-400 workers.

It’s always a neat experience to observe one of these impressive invertebrates while out on a hike.

Red Milk Snake

Red Milk Snake_5475

I saw this beautifully colored serpent crossing Snake Road while visiting southern Illinois. It’s overall pattern is similar to the Eastern Milk Snake which I often find in my home state of Ohio.

Red Milk Snake_3626

Its body color can be white, gray, yellow or light tan, with red or orange black bordered blotches. Like the Eastern Milk Snake, its belly is strongly checkered in a pattern of black and white squares.

Red Milk Snake_3622

Red Milk Snakes are secretive and seldom seen out and about. They spend much of their time hiding under rocks and logs or in rodent burrows. They are not particularly large snakes, often only about two feet in length. They subdue their prey by constriction and feed on lizards, snakes and small mammals.

Red Milk Snake_3614

It’s always thrilling to come across this boldly marked, colorful snake in its natural environment.

Ant Mimic Jumping Spider

Ant Mimic Jumping Spider_3695

Working in my yard this weekend, a came across this tiny, yet fascinating invertebrate. It’s very small size and body shaped more like ant than a spider, at first glance, it may be difficult to tell that this creature is a spider.

Ant Mimic Jumping Spider_3706

It walks with its front pair of legs raised in the air as if they were antennae, making it tricky to identify it as a spider when first counting legs. The resemblance to ants is a defense against predators. Many types of ants are pungent to taste and are unlikely to become food for larger predators.

Ant Mimic Jumping Spider_3702

Ant Mimic Spiders often live near ant hills or nests to benefit from the ant’s unsavory reputation for tasting bad. They can be found anywhere ants are found: fields, lawns, gardens, woods, on trees and under stones.

Ant Mimic Jumping Spider_1715

The Ant Mimic Jumping Spider is one of the few species in genus Myrmarachne that is found outside the tropics. Its species name, formicaria means “ant-like” in Latin.

Atlantic Ribbed Mussel

Atlantic Ribbed Mussel_8435

 

While checking out a tiny cove in Rye, New York, I came across several examples of this bivalve that lives in low, regularly flooded marshes and mud flats.

Atlantic Ribbed Mussel_8414

The Atlantic Ribbed Mussel grows 2 to 4 inches in length. Its glossy, oval, grooved shell varies in color from olive or yellowish-brown to black. The shell’s interior is iridescent blue to silvery white.

Atlantic Ribbed Mussel_8421

These creatures are are filter feeders. During high tide, they open their shells slightly to draw in water, filtering out algae and other particles.

Atlantic Ribbed Mussel_8427

They attach themselves to rocks and other surfaces and clumps of mussels can be found half-buried in the mud among marsh grasses.

Atlantic Ribbed Mussel_8405

Mussels perform an important environmental function of filtering water entering marshes during each tidal cycle. This helps clean and clarify the water.

Atlantic Ribbed Mussel_8407

An Atlantic Ribbed Mussel’s age can be determined by counting dark growth rings on the shell. Mussels typically live 10 – 15 years, but more advanced ages are not uncommon.

Asian Shore Crab

Asian Shore Crab_8360

While visiting New York last week, I flipped a few rocks along the East Coast and encountered quite a few of these small crustaceans; they were often found in dense aggregations.

Asian Shore Crab_8374

Adults are small, measuring about an inch and a half in shell width. They have a squarish shell and light and dark bands on their legs.

Asian Shore Crab_8366

Though native to the western Pacific Ocean from Russia to Hong Japan, it is likely that Asian Shore Crabs were discharged at harbors in the United States as larvae from the ballast water of a cargo ship.

Asian Shore Crab_8385

This creature is not a picky eater, and feeds on a wide range of plants and animals. It can tolerate a wide range of environmental conditions. These characteristics help to make it successful in areas where it is not native.

Asian Shore Crab_8378

Although undeniably cute, Asian Shore Crabs have displaced both large and small native crabs along the East Coast.

Buttonbush

Buttonbush_7326

Walking along the Ohio & Erie Canal Towpath, I noticed this distinctive white, spherical flower with needle-like projections growing on a shrub.

Buttonbush_7308

This plant is a member of the Coffee Family and is native to eastern and southern North America. Like the Coffee Plant, its leaves are glossy green and up to 4 inches long and 2 inches wide. It’s unusual flowers are a source of nectar, attracting butterflies, bees, moths, hummingbirds and 20-something other species of birds.

Buttonbush_7321

Buttonbush can be found in wet habitats such as marshes, shorelines, ditches and areas near the rivers and ponds. It is one of the first plants that will appear in areas destroyed by floods.

Buttonbush_7310

This is multi-branched, round-shaped shrub typically reaches 6 to 12 feet in height. Its older trunk bark is attractively diamond-patterned with lattice-like raised ridges. Its fruit is a reddish-brown, round-shaped capsule filled with two seeds. It ripens during September and October. Ducks and other waterfowl eat Buttonbush seeds.

Buttonbush_7315

If you come across a Buttonbush in bloom and patiently observe the activity around it, you’ll be likely to see spiders, bees, butterflies, moths, wasps and perhaps even a hummingbird buzzing around its flowers.

Buttonbush_7314

You’ll understand very quickly why this plant is so important native wildlife and our environment.

Mountain Chorus Frog

Mountain Chorus Frog 236

This amphibian is native to Ohio, yet I have yet to find it in my home state. I have encountered it in West Virginia and Kentucky though.

Mountain Chorus Frog217

Mountain Chorus Frogs are small (1 to 1-1/4 inches long) and can be distinguished from Ohio’s similar Western Chorus Frog by the presence of two dark, curved stripes on the back which look like reversed parentheses.

Mountain Chorus Frog 221

They can be heard calling in shallow water near forests or in wooded ponds, typically from February to April. Their call resembles the sound made by rubbing one’s finger over the teeth of a hard plastic comb.

Mountain Chorus Frog 219

Outside of breeding season that can be found on damp, wooded hillsides often quite some distance from standing water. It’s always fun to come across this elusive little creature that goes about its life largely unnoticed by humans.

Eastern Black Kingsnake

IMGP0052

Although this serpent lives in my home state of Ohio, it is uncommon there, listed as a “species of concern” and only found in a few counties. I’ve found several examples on different visits to various parts of Kentucky though.

Eastern Black Kingsnake 10 149

This is a shiny, mostly jet black snake with a white, yellow or cream belly. Some spotting may occur particularly along its lower sides. The adult length averages about 3-1/2 feet long. Like other Common Kingsnakes, its head is not significantly offset from its body.

Eastern Black Kingsnake 180

This species is a habitat generalist and can be found in hardwood and pine forests, bottomlands and swamps, farmlands, hillsides, meadows and suburban areas. Most of the examples I’ve found were under sheets of rusted metal in abandoned fields (including this one which has cloudy eyes because it is going through a shed cycle).

Eastern Black Kingsnake 0032

Eastern Black Kingsnakes are powerful constrictors eat a variety of different kinds of food, including snakes, lizards, rodents, birds and turtle eggs. They are resistant to the venom of pit-vipers and they readily eat copperheads, cottonmouths, and rattlesnakes.

Eastern Black Kingsnake 05-10 153

Kingsnakes are one of my favorite snakes to find in the wild and encountering these handsome reptiles has always been a herping highlight.

Six-spotted Tiger Beetle

Six-spotted Tiger Beetle_3835

At this time of the year it’s not unusual for me to encounter this half-inch-long, metallic green insect with conspicuous sickle-shaped jaws and large, bulging eyes on the sides of its head. I usually see them on dirt paths near waterways during warm weather.

Six-spotted Tiger Beetle 033

Adult beetles are fast runners and fliers. When they fly, they usually stay within three feet of the ground. They are very active during the day, moving rapidly in short bursts, often landing several feet in front of you only to take off again when you catch up to them.

Six-spotted Tiger Beetle_5459

They are predators of other insects and can catch prey on the ground and in the air. These shiny beetles are among the fastest runners in the insect world. The Six-spotted Tiger Beetle pounces on its prey, capturing it with its powerful jaws.

Six-spotted Tiger Beetle_5467

Because tiger beetles have excellent vision, you might have trouble getting close to one. For best results, sneak up on one very slowly to observe magnificent insect close up.

Six-spotted Tiger Beetle_8972

The Six-spotted Tiger Beetle’s eye-catching brilliance and fascinating predatory behavior have made it a longtime favorite with naturalists.
