Life on the Forest floor ….. Wood from a fallen tree.

Dead wood
Life on the forest floor
Nigel Borrington 2019

The forest floor is always full on life old and new, it offers amazing images with a macro lens and man times I just love getting in close and then waiting to see the captured images when I get home 🙂 .

In this image it was not until I looked closer that I noticed a small grub( Bottom Center of the image), munching away at all the dead wood, its these little insects that act as the recycling machines of the forest as they turn all the fallen trees and branches into a compose for new tree growth.


All the elements that nature needs …….

Sheeps bit – Wild flowers

The Slate Quarry at (Ahenny, Windgap, Co. Kilkenny) is one of our best local locations for wild life and wild flowers – at this time of year. There are three or four old open quarry pits most of which now form small lakes, along with many heaps of slate that remained in place after all the good slate in the area had been removed. In the summer the lakes are used for swimming in.

I often visit and today I captured these blue sheep’s bit flowers at lunch time and they cover most of the tops of the old slate heaps. Natural blue wild flowers are one of natures rarest finds so it was a true pleasure to see such a large amount growing in one place.

Here are some details about these very special little plants ….

Sheep’s-bit

Scientific Name: Jasione montana
Irish Name: Duán na gcaorach
Family Group: Campanulaceae

Also known as Sheep’s-bit Scabious, the books say this is a rather variable plant and can easily be mistaken for a composite or a scabious, but theAlso known as Sheep’s-bit Scabious, the books say this is a rather variable plant and can easily be mistaken for a composite or a scabious, but the florets have a 5-toothed calyx and not a pappus. Also the anthers in this plant do not project – unlike those of Devil’s Bit Scabious. I hope this helps. It is a pretty little downy biennial which grows in rocky places, cliffs and heaths up to 40cm high. It has bright blue rounded flowers aggregated in a compact head (15-25mm) which is borne on a slender stem. Its leaves have wavy edges and are hairy, grey-green and short-stalked. The plant is on flower from May to September. This plant is a native and belongs to the family Campanulaceae.

I first identified this flower in Laragh, Co Wicklow in 1976 and photographed it in Glenmalure, Co Wicklow in 2006.

It a pleasure to be into photography at this time of year, nature is in full flight and at her very best.

For many personal reasons I have no been posting regularly here on my blog for the first time in many years so it also a pleasure to be able to make a start again.

Last week I spent as much time as I could taking my much love Nikon and macro lens out into our local woodlands and capturing lots of nature images. Here is just one of the many images I managed to get the time to process so far.

Now that I am starting again to post here, I plan to be very specific this summer with my images and close-up nature images will be one of my main areas.

Wood White

Family: Pieridae Swainson, 1820
Subfamily: Dismorphiinae Schatz, 1887
Tribe: Leptideini Verity, 1947
Genus: Leptidea Billberg, 1820
Subgenus:
Species: sinapis (Linnaeus, 1758)
Wingspan 42mm

The Wood White is one of our daintiest butterflies with one of the slowest and delicate flights of all the butterflies. When at rest, the rounded tips of the forewings provide one of the main distinguishing features between this butterfly and other “whites”. Adults always rest with their wings closed. In flight, the male can be distinguished from the female by a black spot at the tip of the forewings that is greatly reduced in the female. This butterfly lives discrete colonies and was only recently separated from the visibly-identical Cryptic Wood White. This local species can be found in central and southern England and also in Ireland on the limestone pavements of Clare and South-east Galway. This species is absent from Scotland, the Isle of Man and the Channel Islands.


Octobers wood land nature, Spending some time with the spiders

A Noiseless Patient Spider – Poem by Walt Whitman

A noiseless, patient spider,
I mark’d, where, on a little promontory, it stood, isolated;
Mark’d how, to explore the vacant, vast surrounding,
It launch’d forth filament, filament, filament, out of itself;
Ever unreeling them—ever tirelessly speeding them.

And you, O my Soul, where you stand,
Surrounded, surrounded, in measureless oceans of space,
Ceaselessly musing, venturing, throwing,—seeking the spheres, to connect them;
Till the bridge you will need, be form’d—till the ductile anchor hold;
Till the gossamer thread you fling, catch somewhere, O my Soul.

What do Hover flies and Insect see with their compound eyes ?

Hover Flies, such as the this one above, look at the world in quite a different way than humans do. The structure and function of a flies eye are completely different from ours, and so they see shapes, motion and color differently. Flies are also able to see light in a way humans cannot.

Structure of a Compound Eye

Compound eyes are made up of thousands of individual visual receptors, called ommatidia. Each ommatidium is a functioning eye in itself, and thousands of them together create a broad field of vision for the fly. Each ommatidium is a long, thin structure, with the lens on the outer surface of the eye, tapering to a nerve at the eye’s base. When the ommatidium receives light, it is filtered through the lens, then a crystalline cone structure, pigment cells and visual cells. Every ommatidium has its own nerve fiber connecting to the optic nerve, which relays information to the flies brain.


Flies Can’t Focus

A human’s eye is attached to muscles that allow it to move, expanding the field of vision and making it possible for the eye to gather more information about its surroundings. Instead of moving their eyes, flies receive information from several different points simultaneously. A flies eyes are immobile, but because of their spherical shape and protrusion from the flies head they give the fly an almost 360-degree view of the world. In a human eye, the pupil controls how much light comes into it, which is focused by the lens onto the retina. The retina then relays information to the brain via the optic nerve. Because fly eyes have no pupils they cannot control how much light enters the eye. With no control over how much light passes through the lens, the fly cannot focus the image it sees. Flies are also short-sighted — a visible range of a few yards is considered good for an insect.

The Mosaic Effect

The best analogy to describe a flies vision is to compare it to a mosaic — thousands of tiny images convalesce, and together represent one visual image. Each one of these pictures represents information from the fly’s individual ommatidium. The effect is much like how we see stippling or newspaper print — up close the image is a lot of tiny dots, but take a step back and it’s a complete image. The more ommatidia a compound eye contains, the clearer the image it creates.

Motion Detection

There’s a reason why flies are especially jumpy creatures that take off at the slightest flinch. A flies vision is nowhere near as clear or effective as a human’s, but it’s especially good at picking up form and movement. As an object moves across the fly’s field of view the ommatidia fire and stop firing. This is called a flicker effect. It’s similar to how a scrolling marquis works — with lights turning on and off to give the illusion of motion. Because a fly can easily see motion and form, but not necessarily what the large moving object is, they are quick to flee, even if the moving object is harmless.


Interpreting Light Waves

Flies have limited color vision. Each color has its own wave frequency, but flies have only two kinds of color receptor cells. This means they have trouble distinguishing between colors, for instance discerning between yellow and white. Insects cannot see the color red, which is the lowest color frequency humans can see. However, houseflies have the ability to see polarized light, but humans cannot differentiate between polarized and unpolarized light. Polarized light is light in which the waves travel only in one plane.


Macro Images – Wolf Spider

Wolf Spiders are members of the family Lycosidae. They are so named because their method of hunting is to run down their prey like that of a wolf. Wolf Spiders are robust and agile hunters that rely on good eyesight to hunt, typically at night. Wolf Spiders resemble nursery web spiders (family Pisauridae), however, they carry their egg sacs by attaching them to their spinnerets (instead of by means of their jaws and pedipalps).

Wolf spider Characteristics

Wolf Spiders range from about half an inch to 2 inches in length. They are hairy and typically brown to grey in colour with a distinct Union Jack impression on their backs. The spiders undersides are light grey, cream or black, sometimes salmon pink.

Wolf Spiders have eight eyes arranged in three rows. The bottom row consists of four small eyes, the middle row has two very large eyes and the top row has two medium-sized eyes.

Wolf Spiders depend on their good eyesight to hunt. Their sense of touch is also acute. The sides of their jaws may have a small raised orange spot or ‘boss’.

Because they depend on camouflage for protection, Wolf Spiders do not have the flashy appearance of some other kinds of spiders. In general their colouration is appropriate to their favoured habitat.

Wolf Spiders eyes reflect light well and one way of finding them is to hunt at night using a flashlight strapped to ones forehead so that the light from the light is reflected from their eyes directly back toward its source.

Wolf spider Habitat and Webs

Wolf spiders can be found in a wide range of habitats both coastal and inland. These include shrub lands, woodland, wet coastal forest, alpine meadows and suburban gardens.

Wolf spiders are commonly known as household pests as when the weather starts getting colder, they look for warm places to overwinter in homes. Wolf Spiders are commonly found around doors, windows, house plants, basements, garages and in almost all terrestrial habitats. Wolf Spiders do not spin a web, instead, they roam at night to hunt for food. Wolf spiders are often confused with the Brown Recluse spider, however, they lack the violin-shaped marking of the Recluse. The wolf spider is shy and is most likely to run away when disturbed.

Wolf spider Diet

Two Wolf spider species are known to be predators of cane toads. Lycosa lapidosa will take small toads and frogs while Lycosa obscuroides has been noted biting and killing a large toad within one hour.

Wolf spider Reproduction

Mating takes place outside the females burrow at night. Some adult male Wolf spiders of smaller-sized species are known to disperse by air in order to find mates. The male is attracted by scent markings left by the female, often associated with her drag-line silk. Males perform a courtship ritual prior to mating, often involving complex leg and palp signaling to the female.

The female Wolf spider constructs an egg sac of white papery silk, shaped like a ball with an obvious circular seam, which she then carries around attached with strong silk to her spinnerets. When the spiderlings hatch, they are carried around on the females back until they are ready to disperse by ballooning or on the ground. Such a high degree of parental care is relatively unusual among spiders. Wolf spiders live for up to 2 years.

Wolf spider Venom

The Wolf Spider is not aggressive, however, it will inject venom freely if continually provoked. Symptoms of its venomous bite include swelling, mild pain and itching. Though usually considered harmless to humans, its bite may be painful.
