Scribbly Gum Image

 

This image was developed in a similar fashion to the previous one. The colours are different; it depends on the time of year the original image was taken. The outer bark is shed at various times throughout the year, but mostly late winter & early spring. The new bark that shows through underneath is bright cream and the scribble insect tracks are a rich red-brown. As the year goes on, the bark colours fade until they are a subtle blue/grey and the tracks are dark grey.

He looks very sad, this one – a grey, downcast creature, feeling rather vulnerable.

New Scribbly Gum Image

Here is a new way of treating my Scribbly Gum characters. I’m pleased with this; desaturating  the ground and using layer adjustments to enhance the figure brings out what I see in them without losing the context.

 

Frog-Prince

See him? I call him the Frog Prince. He seems a little pensive, for all his funny hat. Perhaps he is not sure whether he preferred being a frog.

A Different Method for the Scribbly Gum Images

Earlier on I found another way to treat the “background” for these little faces I see in the insect tracks that are the scribbly gum ‘scribbles’. In photoshop I can ‘paint bucket’ into the bark texture. Depending on the settings, I can end up with a texture which is a bit like an etching, which I think throws the ‘figure’ into relief against this highly complicated ‘ground’.

New Scribbly Gum images

I have been exploring these for some time – is it really 6 months since I last posted anything? Time flies …..
I have made the ‘background’ (what my mind sees as ‘not the image’) black for some scribble creatures, like these ones.

Funny sort of creatures, aren’t they? They seem to have such distinct personalities, you could begin to make up lives for each one; real caricatures. Feel free, anyone, to suggest their story!

I just came across this great photographer in Timemachine magazine. This is beautiful, evocative work – have a look! It is all about the changes taking place in Hungary and central Europe, with such a sense of loss and mystery.  Tamas Dezso

Thoughts on Christmas Beetles

Various ideas are rolling around in my head in response to this general theme. (See previous posting on the subject).

  • I can understand why my efforts – eg, not using pesticides or herbicides for 25 years – have not resulted in any local difference. If the beetle larvae need native grasses to thrive, then acres of kikuyu grass will not do them any good. The problems are too big, too global for me to have any impact.
  • This really makes me depressed. My being depressed does not save a single beetle. It does make me irritable and a general pain to be around.
  • This experience is making me understand the disaffection of the Australian aboriginal people a bit better. I know how the sadness of losing natural diversity makes you want to devote yourself to grief and mourning, to curl up, give up and just wait for the end of the world; the loss of culture, of whole families of cultures, languages, beliefs, and knowledge of country must be infinitely more disabling.
  • The aborigines looked after this country for at least 50,000 years. in that time, early on, the megafauna were lost, and the use of fire changed the landscape to a park-like system of belts of open grasses and closed scrub. See “The Biggest Estate on Earth: How Aborigines Made Australia” by  Bill Gammage Allen & Unwin 2012. A brilliant book – this is a quote from a review for the Prime Minister’s Literary Award for this book (no attribution found). “Across Australia, early Europeans commented again and again that the land looked like a park. With extensive grassy patches and pathways, open woodlands and abundant wildlife, it evoked an English country estate. With implications for us today, Bill Gammage explodes the myth that pre-settlement Australia was an untamed wilderness, revealing the complex, country-wide systems of land management used by Aboriginal people. Once Aboriginal people were no longer able to tend their country, it became overgrown and vulnerable to the damaging bushfires we now experience. What we think of as virgin bush in a national park is nothing of the kind.” (My italics.)
  • In less than 250 years, we Europeans have wreaked total havoc. 100’s of species lost, many, many more in substantial decline, near-dead river systems, extensive salination of the land, erosion, impacted soils, and so on.
  • There is no political will to change any of this. Australians, as shown in their recent voting, are more than ready to swap their heritage (the land’s wellbeing) for a mess of potage (slightly reduced electricity charges.) End of story.

Where have all the Christmas Beetles gone?

This is copied from the Australian Museum, because I was wondering if anyone else had missed these wonderful insects and googled the question. It seems the answer is yes, but because no one has had the funding to do a proper study, the evidence is “only anecdotal”. How many other less obvious insects have gone the same way? I feel strangely alone in my concerns; the world is becoming diminished and little notice is taken.

The evidence suggesting a decline is anecdotal yet compelling.

It’s that time of year when retailers bemoan the fickle habits of consumers, people clean out their barbeques and Christmas beetles crash into windows and pile up around streetlights . . . or do they? Entomologist Chris Reid investigates.
Each year I am asked, ‘Where have all the Christmas beetles gone?’ Have they really declined, and what is a Christmas beetle anyway?
Scarabs
Christmas beetles are a type of scarab (a group that includes dung beetles and chafers). Compared to other scarabs, Christmas beetles (genus Anoplognathus) are large and chunky, somewhat flattened in shape and with metallic brown, yellow or pink colours. They most obviously make themselves known in midsummer by swarming around lights in towns throughout eastern Australia.
The adults generally feed on eucalyptus leaves. They prefer open woodland to forest and thrive in pastures wherever trees have been left in place. In farmland they can form dense masses on the remaining eucalypts, chomping through leaves, sometimes killing their hosts. In contrast to the adults, the larvae (grubs) feed on roots, usually of grasses. Some species are economically important pests of eucalytpus plantations while others are implicated in dieback – the decline of mature trees in landscapes like those in NSW’s New England Tableland.
Diversity
There are 36 species in the genus with all but one unique (endemic) to Australia and 21 species found in New South Wales. At least 10 species occur in the Sydney region – more if the Blue Mountains are included. Because they are such a feature of the eastern Australian experience some common species have been given English names, such as the Washerwoman, Anoplognathus porosus, and (rarer) King Beetle, Anoplognathus viridiaeneus (see photos, right). Distinguishing some species can be tricky, but it helps to examine the hairs on their ‘bums’ (posterior). (This is something of an in-joke among entomologists but it actually works for this group!)
Decline?
The evidence suggesting a decline is anecdotal yet compelling. In the 1920s, they were reported to drown in huge numbers in Sydney Harbour, with tree branches bending into the water under the sheer weight of the massed beetles. You won’t see that these days, and I’ve never seen a Christmas beetle come to light where I work, next to Hyde Park. While public concerns suggest that numbers are also much smaller in the suburbs, I’ve found at least five species near my home, clustered around street lights at the southern edge of Royal National Park, 55 kilometres south of Sydney.
Plain answers
If we accept that Christmas beetles have declined in central Sydney, the next question is ‘why?’. The dual life history provides a clue. The adults need eucalypt leaves, and the larvae need the roots of grasses, presumably native grasses. An important habitat for them, the Cumberland Plain woodland, was once widespread in Western Sydney, but less than 10% remains.
Sydney is now bulging at the seams with 4.5 million people, and Western Sydney has absorbed much of the growth. The beetles’ former habitat is now a brick, concrete and tarmac jungle. Christmas just isn’t what it used to be, is it?
