Bag Worms

Bagworms

The Psychidae (bagworm moths, also simply bagworms or bagmoths) are a family of the Lepidoptera (butterflies and moths) which are much overlooked

"Bags" resemble caddisfly cases in their outward appearance – a mass of (mainly) plant detritus spun together with silk on the inside.. The case is based on a silk tube, to which the larva attaches various bits of plant, matter such as lichens, algae, sand, insects and debris. Like Caddis Psychidae larvae construct cases that can be identifiable through combinations of shape, size and material , this is not always reliable due to similar constructions in other species so rearing is recommended

In the larval stage, bagworms extend their head and thorax from their mobile case to devour the leaves of host plants, often leading to the death of their hosts

Bagworm caterpillars make distinctive 1.5 to 2 inch long spindle-shaped bags that can be seen hanging from twigs of a variety of trees and shrubs. Sometimes the bags are mistaken for pine cones or other plant structures. 

Adult females of many bagworm species have only vestigial wings, legs, and mouthparts. In some species, parthenogenesis is known. The adult males of most species are strong fliers with well-developed wings and feathery antennae but survive only long enough to reproduce due to underdeveloped mouthparts that prevent them from feeding. Their wings have few of the scales characteristic of most moths, instead having a thin covering of hairs.

11.001 B&F 0180) Diplodoma laichartingella


The larva builds a case, covered with small fragments of plant matter and other particles, and feeds on lichens, decaying plant matter and detritus. The larval period usually lasts for two years.During the Winter months, cases can be found tucked well into the characteristic hollows around the roots of mature Beech trees, the larvae becoming active from late March and early April, moving back up the tree trunks to begin feeding.

11.009 ... B&F 0184 Luffia ferchaultella (Stephens, 185


Chris Manley (in his `British Moths`, 2nd Edition 2015) states that it can be `abundant on tree trunks in damp woods` and other sources mention old fence posts (or other wooden objects) or old walls where powdery grey lichens grow. The latter can be locally frequent, even in urban areas. Luffia is said to prefer `shady places` rather than tree trunks and walls etc in full sun.March/early April) is said to be the best time to find the distinctive larval cases. as cases are, by then, full sized (up to 6mm) and easier to spot.

The King of Fishers


Size and Colour

Common Kingfishers measure 17 – 19 centimetres in length, weigh between 34 – 46 grams and have a wingspan of 25 centimetres. Their beak is around 4 centimetres long and pointed. Kingfishers have short, orange coloured legs.

Kingfishers have very keen eyesight. The kingfisher has monocular vision (in which each eye is used separately) in the air and binocular vision (in which both eyes are used together) in water. The underwater vision is not as a sharp as in the air, however, the ability to judge the distance of moving prey is more important than the sharpness of the image.

Where To see Them

Kingfishers are found by still or slow flowing water such as lakes, canals and rivers in lowland areas. In winter, some individuals move to estuaries and the coast. Occasionally they may visit garden ponds if of a suitable size. They can be seen all year round. Cromwell Bottom is an ideal location for theses birds with a unique comnbination of the River Calder, Canals and Lagoons

General Facts

Kingfishers are  vulnerable to hard winters and habitat degradation through pollution or unsympathetic management of watercourses. Kingfishers are amber listed because of their unfavourable conservation status in Europe. It is estimated there are 3,800-4,600 breeding pairs in the UK

Many young kingfishers die within days of fledging, their first dives leaving them waterlogged so they end up drowning.Because of the high mortality of young, kingfishers usually have two or three broods a year, with as many as 10 in a brood.

Preening Ritual 

Kingfishers live in burrows which are often insanitary therefore a good preening regime is essential in keeping feathers clean and in working condition

Kingfisher 3091

Kingfisher 3068


Like all small birds the Kingfisher remains wary of  overhead activity to avoid presation by raptors

Feeding

The common kingfisher hunts from a perch 1–2 m (3.3–6.6 ft) above the water, on a branch, post or riverbank, bill pointing down as it searches for prey. It bobs its head when food is detected to gauge the distance, and plunges steeply down to seize its prey usually no deeper than 25 cm (9.8 in) below the surface

Kingfisher 3021


Territory

Like all kingfishers, the common kingfisher is highly territorial; since it must eat around 60% of its body weight each day, it is essential to have control of a suitable stretch of river. It is solitary for most of the year, roosting alone in heavy cover. If another kingfisher enters its territory, both birds display from perches, and fights may occur, where a bird will grab the other's beak and try to hold it under water. Pairs form in the autumn but each bird retains a separate territory, generally at least 1 km (0.62 mi) long, but up to 3.5 km (2.2 mi) and territories are not merged until the spring.

The courtship is initiated by the male chasing the female while calling continually, and later by ritual feeding, mating usually following.

All The leaves are Brown ?

This is a very simplied view to leaf Colour. With the Season under way Natures Canvas paints its own Picture
video

GREEN- Is due to a pigment know as Chlorophyll the chlorophyll's green color dominates and masks out the colors of any other pigments that may be present in the leaf during the grow season. As Autumn approached Trees undergo practical changes due to harsher temperature and lower light levels allowing other colours to appear Chlorophyll, which gives leaves their basic green color. It is necessary for photosynthesis, the chemical reaction that enables plants to use sunlight to manufacture sugars for their food. Trees in the temperate zones store these sugars for their winter dormant period.

COLOUR

Veins that carry fluids into and out of the leaf are gradually closed off as a layer of special cork cells forms at the base of each leaf. As this cork layer develops, water and mineral intake into the leaf is reduced, slowly at first, and then more rapidly. It is during this time that the chlorophyll begins to decrease.

Often the veins will still be green after the tissues between them have almost completely changed color.


YELLOW & ORANGE

As the chlorophyll breaks down, the green color disappears, and the yellow to orange colors become visible and give the leaves part of their fall splendor.Orange Yellows can be due to carotenes and xanthophyll. Carotenoids, which produce yellow, orange, and brown colors in such things as corn, carrots, and daffodils, as well as rutabagas, buttercups, and bananas.

RED

At the same time other chemical changes may occur, which form additional colors through the development of red anthocyanin pigments. Some mixtures give rise to the reddish and purplish fall colors of trees such as dogwoods.Anthocyanins, which give color to such familiar things as cranberries, red apples, concord grapes, blueberries, cherries, strawberries, and plums. They are water soluble and appear in the watery liquid of leaf cells.

Weather Affects Color Intensity

Temperature, light, and water supply have an influence on the degree and the duration of autumn color. Low temperatures above freezing will favor anthocyanin formation producing bright reds in maples. However, early frost will weaken the brilliant red color. Rainy and/or overcast days tend to increase the intensity of fall colors. The best time to enjoy the autumn color would be on a clear, dry, and cool (not freezing) day

Catch The Rainbow

Alexander's band or Alexander's dark band is an optical phenomenon associated with rainbows which was named after Alexander of Aphrodisias who first described it in 200 ADIt occurs due to the deviation angles of the primary and secondary rainbows. Alexander's band lies between the two rainbows.
