Distracted by the ground layer

As the woodland floor starts to burst into life there will be lots to observe and enjoy over coming weeks.

Orchids, including the Dwarf Greenhood Pterostylis nana, were a nice distraction during a walk at the weekend in the Mia Mia. I’ve no idea what the other greenhood pictured here might be … any ideas welcome!

[Note: It seems that the unidentified orchid is most likely the Emerald-lip Greenhood Pterostylis smaragyna. Many thanks to readers who offered their thoughts. There were a number of plants, all with single flowers – this species typically has multiple flowers but not always it seems].

Ants, an autumn orchid et cetera

When all else fails, the insect macrophotographer can always rely on ants. In times of low invertebrate numbers, they are always there running the show. On a warm autumn day, the Meat Ants Iridomyrmex purpureus near our dam have been out and about. I was intrigued to watch one industrious lady struggle mightily to drag a Grey Box leaf towards the nest. She made absolutely no progress with it at all and none of her sisters seemed to want to help. I have no idea what she wanted it for.

I think the raised leg was more for leverage than a request for help.

By night, I found an ant with a significant mite infestation. I had seen this in previous years and the species of ant seemed the same. On bowerbird.org.au it was suggested that the previous ant was a Polyrhachis queen and this looked the same. My source said it was not uncommon to see them with mites. An both of my encounters with ants in this state were in mid-autumn.

Flies of all shapes and sizes are common at the moment, but mostly very uncooperative sitters for portraits. Lots of Robber Flies seem to enjoy afternoon sun bathing and even a bit of amorous coupling, but have steered well clear of my lens. Bee Flies (Geron sp.) are also around in good numbers and tend to be more relaxed.

Whilst ants, flies and moths are abundant at the moment, we still seem short on the usual quotient of insects that chew leaves and suck sap. So I was pleased to find at least a couple of these recently. There have been a few leafhopper nymphs snuggling into the angles of branches of wattles and eucalypts to avoid detection.

I’ve also found a few tiny weevils on Golden Wattle leaves.

And finally, I was pleased to find a Parson’s Band orchid (Eriochilus cucullatus)or two putting out some flowers.

A colourful carpet

Before another burst of welcome spring rain, the Mia Mia was bathed in sunshine this morning. While the birds didn’t perform for the camera a carpet of wildflowers more than compensated.

What a great time of year to be in the bush. It’s hard to know where to look, with a carpet of wildflowers emerging and lots of activity in the canopy above.

In a different light … an exhibition by David Oldfield

In a Different Light – Australian Native Flower Photographs in Ultraviolet Light … an exhibition by David Oldfield

Why would you want to take such photos in the first place? This sounds like the question “Why would you want to climb Mount Everest?” The answer is not the one given by British mountaineer George Mallory – “Because it’s there” but probably more “Because nobody else is doing that for Australian flowers”.

David Oldfield was bitten by the photo bug while at school in England long before digital cameras were available and learnt all about the wonders of darkroom work. These days you can get digital cameras modified by specialist companies so that you can take photos invisible to human eyes. There is a small band of photographers around the world who enjoy seeing what happens when you use cameras far beyond what they were designed to do.

Many flowers have dark patterns on their petals which are visible under Ultraviolet (UV) light but invisible to the naked human eye. Scientific studies of honeybee vision have shown that their eyes are sensitive to UV, blue and green light. It appears that the dark patterns visible in UV may assist pollinating insects, such as honeybees, to find the nectar or pollen on the flowers. Overseas UV photographers have reported the existence of dark “bulls-eye” patterns on yellow petals in their images.

David has found that Australian flowers show similar patterns, as you will see if you visit his exhibition at the Newstead Arts Hub between 1st and 23rd June, open every Saturday and Sunday 10 am to 4 pm. It will also be open on Queens Birthday Monday 11th June.

The official opening will be Saturday 1st of June at 2pm. All welcome!

The walk is always worth it!

It was too dull to chase birds with the camera late this afternoon … for a change my focus turned to other matters.

The end of my stroll coincided with the sudden arrival of a mixed species feeding flock – Flame Robins, Grey Shrike-thrush, Golden Whistler, Speckled Warblers, Striated and Buff-rumped Thornbills … not a bad finish!

The remarkable world of wild orchids

Newstead Landcare are delighted to present a talk by Emily Noble on ‘The remarkable world of wild orchids’ at 8.00pm on Thursday 21st March at Newstead Community Centre.

As the Secretary of the Field Naturalists’ Club of Ballarat, Business Manager of the Ballarat Environment Network, Coordinator of the 540ha Clarkesdale Bird Sanctuary in Linton for Birdlife Australia, and proud owner of a bush block south-west of Ballarat that is home to at least fifty different wild orchids, Emily has ample opportunity to pursue her interest in orchids and their interactions with the co-habitants of their environment. Trying to catch these interactions on camera provides her with many unexpected insights into their ecology, helping inform her conservation activities, and providing a source of ongoing wonder.

Come along to learn more about these remarkable plants and their fascinating relationships with their world.

All are welcome to Emily’s presentation and supper afterwards. There will be no business meeting to sit through. A gold coin donation would help us cover costs.

Some images (all by Emily) below to whet your appetite!

What a ‘combo’

What a great time of year … the combination of Spring wildflowers and striking woodland birds is on offer at present in the bush around Newstead.

The area around Bruce’s Track is particularly important for its diversity of wildflowers and significant woodland birds. Red-capped Robins and Speckled Warblers are just two of the notable species that make their home on this patch. They were too quick for the camera at the weekend, but a Scarlet Robin posed beautifully as a consolation.

‘Going off’

In birding terms, the Muckleford bush is ‘going off’ at present.

There will be some pretty interesting birds (and flora) to show over coming days … here is a taste.
