Speckled Emperor Moth

What the caterpillar calls the end of the world, the master calls a butterfly.
~ Richard Bach

A Speckled Emperor Moth, (Wattled Emperor Moth, Mopane worm) resting on a Restios plant in my garden. It is from the Saturniidae (Silk Moths) family. I actually found her inside the house and brought her out to safety (not sure how SAFE it is...?) and she seemed quite content to just rest a while before disappearing into the thickets.

This moth is widely distributed throughout southern, central and east Africa. Across most of its distribution, the species is bivoltine, with the first generation emerging from pupation in November to December and the second in February to March, only in more arid areas is it univoltine.

Adult moths lay a single cluster of 50 to 200 eggs around twigs or on the leaves of host plants over a two month period. After approximately ten days, the larvae emerge and then pass through five instars before pupation. Instars I to III of the caterpillars are strictly gregarious and will forage together in aggregations of 20 to 200 individuals. After moulting into instar IV, caterpillars disperse immediately to become solitary. The larval stage lasts approximately 6 weeks, during which time the caterpillars undergo a 4000 fold increase in body mass. At the end of the larval stage, the fifth instar caterpillars burrow into the soil, where they undergo a period of diapause. Eclosion occurs either one or six to seven months after pupation, depending on the generation. The non-feeding adult stage lasts only two to three days, during which time the only function of the imago is to find receptive mates and to oviposit.

Pippin, the Bushbaby

W&N watercolour in my Moleskine Nature Journal

This is Pippin, whom I was lucky enough to have in my life for a few weeks after I rescued him from children who were stoning him, as a result of which he lost the use of his left eye. After nursing him back to health, he spent a couple of weeks living in my indoor garden in my lounge, often bounding onto my shoulder for a snack. When I was satisfied that he had fully recovered, I released him in the thickets on the banks of the Magalies River, which was in the vicinity where I had found him. I just hoped and prayed that he had learnt a lesson about people and would stay out of reach of the children ...

Galagos, also known as bushbabies, bush babies or nagapies (meaning "little night monkeys" in Afrikaans), are small, nocturnal primates native to continental Africa and
are almost exclusively seen only at night.

I did this sketch from a photograph I took of him, as he NEVER sits still long enough to be able to sketch him!

Hedgehog Country

HOME FROM HOME

Hedgehogs like to live where their food - largely insects and soil animals - is abundant, and where there are plenty of broad-leaved trees, whose dead leaves they need for making their nests. This means that hedgehogs are widely found in forest and traditional urban farmland, and also in that most artificial of habitats, suburbia.

They are scarce in wetlands, conifer forests, moorlands and mountains, where there are few nest sites and often little food.

But is the hedgehog running out of space, as the bricks and concrete spread across our countryside?

Cemeteries are an ideal habitat for hedgehogs - plenty of nooks and crannies, plenty of food, little disturbance, and no deadly traffic.

Although it is better able to cope in built-up areas than many other animals, it needs parks, gardens, cemeteries and other open spaces in which to forage and nest. If these get built over or tidied up too much, hedgehogs will die out.

My Acacia 'karroo'

My Acacia Karroo (Soetdoring - Vachellia karoo) after the Springs rains October 2009
- Camera : FujiFinepix 2800Zoom

My thorn trees (Acacia) are just coming into bloom and for those that suffer from hay-fever, this is really a bad time of the year, especially if we haven't had much rain. Spring started off very dry, and we have only had some decent rain late in November this year.

During Winter I'm able to prune the tree's low-hanging branches a bit and I just love keeping some of the branches with the HUGE thorns for display around the house - they become quite a conversation piece!

This is one of South Africa's most beautiful and useful trees. It is integrally part of our country's history having been used for everything from raft-making to sewing needles and fencing for the houses of the royal Zulu women. The thorns were even used by early naturalists to pin the insects they collected! It is very widespread throughout southern Africa and there are different forms in some places, which can be confusing. Acacia karroo may be found from the Western Cape through to Zambia and Angola. In tropical Africa it is replaced by Acacia seyal. The name Acacia is derived from Greek "akis" a point or barb. Karroo is one of the old spellings of karoo which cannot be corrected because of the laws governing botanical nomenclature (giving of names).

The sweet thorn makes a beautiful garden specimen. The bright yellow flowers look very striking against the dark green foliage. The rough, dark brown bark is also most attractive. The flowers are sweetly scented and are renowned for attracting insects which are essential to any bird garden. Birds also like to make nests in thorn trees as the thorns offer them some protection from predators. These thorns can grow up to 6" (15cm) long and if they are very thick, it's an indication of an abundance of water. Caterpillars of 10 species of butterflies are dependant on the tree for survival. These include, the club-tailed charaxes (Charaxes zoolina zoolina) and the topaz-spotted blue (Azanus jesous). In cold and dry areas like where I live, the tree is deciduous.

Regions where the Acacia Karroo can be found - I can be found approx. where the red dot is at the bottom of Southern Africa. (Click on pic to enlarge)

Vachellia karoo - Acacia 'karroo' flowers" Watercolour sketch - Maree©

Acacia karroo also known as the Sweet Thorn (Vachellia karoo), is a species of Acacia, and the tree is especially useful as forage and fodder for domestic and wild animals. Apparently, there is no risk of poisoning from it. Goats seem to like A. karoo better than cattle. The flowers appear in early summer in a mass of yellow pompons and make a very good source of forage for honey bees; honey from it has a pleasant taste.

An edible gum seeps from cracks in the tree's bark. The gum can be used to manufacture candy and it used to have economic importance as "Cape Gum". In dry areas, the tree's presence is a sign of water, both above and underground.

It is a tree of open woodland and wooded grassland. It grows to its greatest size when rainfall of 800-900mm is received but can grow and even thrive in very dry conditions such as the Karroo region of western South Africa. The requirement here is for deep soils that allow its roots to spread. Everywhere in its range, however, the tree is easily recognised by its distinctive long white paired thorns and coffee coloured bark, both of which are very attractive. In the tropics it shows little variation but at the southern end of its range it becomes more variable in appearance.

Common names in various languages include Karoo Thorn, Doringboom, Cape Gum, Cassie, Piquants Blancs, Cassie Piquants Blancs, Cockspur Thorn, Deo-Babool, Doorn Boom, Kaludai, Kikar, Mormati, Pahari Kikar, and Udai Vel

The Hedgehog's Future

NEW HORIZONS

What will be the future for hedgehogs as the countryside changes at such an amazing rate? We can only guess, of course, but some changes can only be for the worse as far as hedgehogs are concerned.

Farmlands are not popular with hedgehogs. Insects are controlled by pesticides, so food is short. And there are few trees, meaning that there is little nesting material, and the open fields hold few nesting sites.

The conversion of pasture to arable land means that crops will be sprayed with chemicals, which destroy insects, slugs and worms, the main parts of the hedgehog's diet. And the grubbing-up of hedges and clearance of small patches of waste ground will destroy many good sites for hedgehog hibernation nests.

But as long as hedgehogs prosper in gardens and suburbs, the future isn't entirely bleak!

Farewell to Mbuso

I've been following the progress of the Black Eagles and their chicks (nesting at the Walter Sisulu Botanical Gardens in Roodepoort, Gauteng, South Africa) for many years now, and this is the latest news on their new chick, Mbuso.

Nov 2011
Mbuso, our juvenile Black Eagle chick, will soon be leaving the Garden to establish his own territory. He has been practicing to fly for a while now and hopefully all these efforts have perfected his skills that would allow him to hunt and fend for himself. Even if he still enjoys 'home' his parents will soon chase him out of their territory. We wish him every success and hope he will find a life partner and a suitable habitat to thrive in.

On Wednesday, 31 August, Mbuso the juvenile Verreaux’s eagle took his maiden flight from the nest site at the Walter Sisulu National Botanical Garden. The young eagle was very keen to fledge from the nest at 89 days, and this surely indicates that it is a male, as females usually take a week or so longer, at over 100 days.

Mbuso was very active on the nest at a very young age, with wing exercises starting early on in his second month.

The adult eagles did a sterling job again this year in finding prey and in raising a strong and healthy chick, who will spend another three months in the natal area learning the eagle ways from its parent birds.

The adults will still provide prey for him, and at the end of November the adult male will start to show aggression towards Mbuso, as it will then be time for him to leave the area and find his own home territory.

Although, Black Eagles pair for life, they will replace their companion. In the Roodekrans scenario, the female, Emoyeni replaced her mate 3 times after 2 of them disappeared... Read the full story of the Black Eagles at 'Black Eagle Project Roodekrans'

Queen of my own Compost Heap

"I'm queen of my own compost heap & I'm getting used to the smell!"

Don’t throw away materials when you can use them to improve your lawn and garden! Start composting instead! I find it highly satisfying having a separate bin in the kitchen for egg shells, potato peels, tea bags and other food waste. This gets emptied on top of my compost heap every morning and three times a week all the leaf litter and grass cuttings from the garden is added. I bought a couple of tins of (live) earthworms from a fishing tackle shop and, besides adding them directly to my garden, have also put some into the compost heap and I've been surprised at how they have multiplied!

Compost is the end product of a complex feeding pattern involving hundreds of different organisms, including bacteria, fungi, worms, and insects. What remains after these organisms break down the organic materials is the rich, earthy substance your garden will love. Composting replicates nature’s natural system of breaking down materials on the forest floor. In every forest, grassland, jungle, and garden, plants die, fall to the ground, and decay. They are slowly dismantled by the small organisms living in the soil. Eventually these plant parts disappear into the brown crumbly forest floor. This humus keeps the soil light and fluffy. I therefore hardly ever clean up leaf litter from within my flower beds and though some might not like the look of such an "untidy" garden, I also enjoy watching the Thrushes scratching around in the leaves, enjoying the insects and snails hiding underneath.

This work is deeply simple. All you need is a shady piece of ground large enough for a compost pile that is at least 1×1x2m. First you fork open the soil beneath your proposed pile and arrange a base made of old plant stalks, stems, and soft woody debris. Next you mound on top of this base a deep layer of green, nitrogen-rich materials like garden weeds and grass clippings, mixed with animal manure and kitchen scraps.

The following layer is dry, carbonaceous material like straw and old leaves, or wood chips and sawdust, all well watered so that your pile is nice and moist. Continue to layer your compost green material and then let dry until you have a tall, noble pile, as high as you can reach.

Every compost pile is alive, teeming with billions of invisible micro-organisms digesting your autumn mountain of garbage. In a few short days a healthy compost pile begins to steam with metabolic life as clouds of heat-loving bacteria break down raw protein and complex carbohydrates into amino acids and simple sugars, generating temperatures as high as 72ºC.

This breakdown stage is followed a few weeks later by a build-up stage that lasts for more than a month as complex fungal networks absorb the pile’s free gases into their web work of mycelia, reducing leaching of nutrients, disarming pollutants and disease pathogens, and physically binding soil and compost together, creating stable aggregates that increase water infiltration and retention.

In the last stage of decomposition a few months later—or sooner, if you turn your pile—your mound will be alive with sweet, woodsy-smelling compost laced with up to one hundred industrious compost insects per square foot, intertwined with writhing red compost worms testifying by their presence that decomposition is complete.

Compost Materials
Almost any organic material is suitable for a compost pile. The pile needs a proper ratio of carbon-rich materials, or “browns,” and nitrogen-rich materials, or “greens.” Among the brown materials are dried leaves, straw, and wood chips. Nitrogen materials are fresh or green, such as grass clippings and kitchen scraps.

Food
The 50/50 Rule: A perfect mixture of material consists of brown (carbon-based material) and green (nitrogen-based) material by weight.

Air
To Turn or Not to Turn: The organisms that live inside your compost bin need air to survive. Mix or turn the pile three to five times per season using a pitchfork, garden hoe or shovel. Proper aeration can make a big difference. You will know if your bin is not getting enough oxygen if the pile smells of ammonia.

Water
Moist, Not Damp: The organisms need water to survive, but not too much or they will drown. The ideal moisture level of your compost pile should be like that of a wrung out sponge.

Surface Area
Small is Best: Cut up or shred organic waste materials before placing them into the compost bin. This increases the surface area and speeds up decomposition. You can also store your kitchen scraps in your freezer to speed up decomposition, as your materials break down at the cell level when frozen.

When it comes to WHAT NOT TO COMPOST, the best is to use your common sense. Obvious items like chemically-treated wood products, diseased plants, human and pet waste and MEAT, BONES, AND FATTY FOOD WASTES are big no-no's, as is plastic in any form, tins and glass. Keep it natural and you can't go wrong.

And remember: "A good compost pile should get hot enough to poach an egg, but not so hot it would cook a lobster!"

Rhus lancea (Swart Karee)

People in suburbia see trees differently than foresters do. They cherish every one. It is useless to speak of the probability that a certain tree will die when the tree is in someone's backyard .... You are talking about a personal asset, a friend,
a monument, not about board feet of lumber.
- Roger Swain

21st November 2011 - Finally we've had some GOOD rain! (30mm in a couple of hours) and this will really boost my lawn, which has still been yellow since the winter. The trees are also all fresh, green and sparkling clean, as is evident from the sketch of a few leaves of one of my Karees (Rhus lancea) indigenous to Southern Africa. It's a bit of an untidy tree, with a weird growing habit of the branches backing up on one another and having most of its leaves right at the tip of the branches. It has a graceful, weeping form and dark, fissured bark that contrasts well with its long, thinnish, hairless, dark-green, trifoliate leaves with smooth margins.

The small, inconspicuous flowers are presented as much-branched sprays which are greenish-yellow in colour and are produced from June until September. The male and female flowers occur on separate trees (luckily I have quite a few of them in my garden, so some must be male and some female). The fruit are small (up to 5mm in diameter), round, slightly flattened and covered with a thin fleshy layer which is glossy and yellowish to brown when ripe. The fruits are produced from September until January.

The fruit is eaten by birds such as Bulbuls, Guinea fowl and Francolins. Game animals such as Kudu, Roan antelope and Sable browse the leaves of the tree which can serve as an important food source for them in times of drought. The sweetly scented flowers attract bees and other insects to them. Now re-named Searsia lancea, it is useful in providing natural soil stabilisation and increasing infiltration of rainwater into the soil thus reducing erosion and raising the ground water table.

The leaves of the Karee provide valuable fodder for livestock but can taint the flavour of milk if eaten in large quantities by dairy cattle as a result of the resin contained in them. The tree is also an important source of shade for livestock in certain regions. The bark, twigs and leaves provide tannin. In the past the hard wood was used for fence posts, tool handles and parts of wagons. Bowls, tobacco pipes and bows were also made from the wood. The fruits are edible and were once used as an important ingredient of mead or honey beer. The word karee is said to be the original Khoi word for mead.

Grass Aloes

In the hope of reaching the moon
men fail to see the flowers
that blossom at their feet.
- Albert Schweitzer

Watercolour sketch in my 'Nature' Journal

I found a large clump of Grass Aloes not far from home on the road to Magaliesburg (South Africa), flowering profusely after all the veld fires we have had this winter, spread out over the charred landscape, providing bursts of red colour.

Grass Aloes are an appealing group of deciduous aloes. As the name implies, they grow mainly in grasslands subject to winter fires. Their leaves and colours resemble their habitat, making them difficult to find when not in flower. These largely miniature aloes have very attractive flowers, making them desirable, if difficult, plants to cultivate. Their growing pattern is closely related to the winter fire cycles of the veld here in South Africa, some species responding directly to burning and producing leaves, flowers and later seed after such events.

This interesting Aloe belongs to a group of deciduous aloes known as the "Grass Aloes", which are adapted to grassland habitat and are able to survive both fire and frost during the cold dry months. They are often burned during winter and then re-sprout with the onset of spring.

This well known grass aloe is commonly found along rocky ridges and rocky slopes on the Witwatersrand and Magaliesberg as well as in mountainous areas of the Northern Province and Mpumalanga. In years gone by it was even more prolific, but numbers have been greatly reduced due to development on the ridges and from harvesting by succulent collectors. A number of different forms are found throughout its distribution range.

Grass fires used to be less frequent in earlier centuries. They were initiated by lightning strikes, on the whole, at the beginning of the rainy season in September and October. These fires were ideal in that they cleared the habitat of moribund grass and other vegetation just before grass aloe species initiated their growth cycles.

Fires are more frequent nowadays and may occur at any time during the dry winter months from May until late spring, October. Plants are as a result, left exposed to harsh conditions for many months before they start to grow. Some species are even starting to appear on the endangered species list.
