Thirteen days after I filmed the dragonfly, I saw it in the very same spot on my morning walk. Wondrous. Or so I prefer to think because it could have been another individual of the same species. This strikes me as less likely than it being the original one because I have not noticed a dragonfly of any kind at this location between these two sightings. I have filmed dragonflies repeatedly reoccupying a particular position after an interval and lingering there up to minutes at a time, but never this – a return visit a day short of a fortnight later to the very twig on which it had rested for between a mind-boggling 45 minutes and an hour.
If I hadn’t stopped to ask a friend how much rain had fallen during the night I would never have caught sight of a paper wasp nest attached to a cereus cactus some 4 m high just outside the back gate. The nest is very different to the one I filmed hanging from a metal railing. The wasp is much smaller, only 10mm long. It belongs to a different genus. At most there were no more than 6 wasps attending the nest. Its position was ideal for the camera.
I was delighted to find a lone new lacewing on the garage in Central Avenue. It is more brightly coloured than the mantispid lacewing which has been present on several occasions during the past month or two. Checking images of Queensland lacewings on google, I discovered that this is the ‘Diamond-banded Lacewing’ which occurs in Queensland and NSW.
Today something utterly wonderful happened. I was on my walk in Driscoll Lane when a beautiful turquoise and gold dragonfly whizzed by and entered a hedge a short distance in front of me. Much to my delight I discovered it resting on a twig in full view. I opened up my PANCAM, took several photos and a 30sec video of the dragonfly, unconvinced that they amounted to anything regardless of the fact that the sun was interfering with my view of the monitor. I continued on my walk and bought a couple of items at the post office, determined to return with my Sony on the off chance, in order to do the subject justice. In less than 15 minutes I was back and to my immense relief the dragonfly was where I had left it. I filmed 30 seconds of hand-held footage purely to get the dragonfly on tape before resorting to my tripod. In all, I changed the camera position five times, shooting many minutes of tape. I didn’t check the time of my return, but I would have been filming for between 20 minutes and half an hour, possibly longer. I was setting up my last… Read Complete Text
Broadband service was restored this morning, meaning the outage lasted 6 days. I’m waiting for the settings for the 5 newest videos which I posted on vimeo today, to appear on my website so that I can send out a newsletter to subscribers. The site trawls through vimeo once a day. Consequently the completed videos should show up tomorrow.
The second night shoot of the season in Palm Grove NP was petering out after a promising start, until Robyn spotted a cricket with a small body but inordinately long hind legs which I am pretty sure I have filmed before and Hugh spotted a large, very hairy caterpillar which was new to me. Not far away were two mating flies I also wanted to film with my PANCAM, which I was mysteriously unable to switch on, though there was sufficient battery life the last time I used it. This was the second equipment malfunction of the day. (I was working on the settings of the latest videos when my broadband suffered an outage. Telstra is sending a technician to my place tomorrow morning). We were not far from the entrance when I filmed a large trapdoor spider frozen on the path in mid prowl. Then, just inside the park I was lucky enough to film a pademelon perhaps 15 metres away amongst the vegetation. It was a female with joey, whose presence was revealed by its movement in the pouch. The pademelon sat quietly for several minutes before slowly moving deeper into the undergrowth. This was the first… Read Complete Text
The following email from Greg Edgecombe, sent in July this year, wonderfully highlights the intricacies of species identification. It concerns a House Centipede . Today (Sunday) I sought and received Greg’s permission to post it on my blog – all the more impressive because he is a paleontologist specialising in centipedes and Merit Researcher at the Natural History Museum in London. Previously he worked at the Australian Muesum in Sydney for 14 years. Greg was contacted by Bob Mesibov who is based in Tasmania and has helped me with centipede enquries.
Bob and Peter,
Scutigeromorph IDs based on photos are usually highly dubious and I would definitely put this one into that category. Determining a species requires at least staring at tergite 6 down a microscope at high magnification and working out the relationships of spines, bristles, hairs and whatnot. If there’s only one species known from a well-surveyed area you can stick your neck out a bit more confidently with a photo alone, but SE QLD harbours multiple species of pretty similar Thereuoneminae.
The name Allothereua maculata has been used for pretty much everything in Australia. It’s a Western Australian… Read Complete Text
We drew a blank last week on our first night foray of the new season, but tonight was a success on two counts. At Curtis Falls I at last obtained footage of the Catfish which I have unsuccessfully tried to film before. The vision was never clear, perhaps the water was too murky. There were up to 3 fish in the rock pool below what was no more than a trickle. Also at Curtis Falls, I filmed a Black-spotted Semi-slug on a rock with my PANCAM, obtaining much closer footage of the mollusc than with my Sony.
The potentially new semi-slug I filmed on our 100th night shoot (see 15 May) was confirmed in John Stanisic’s email today as Cucullarion parkini. This is the species he discovered in the Knoll in 1998, which is known to exist only on Tamborine Mountain and nowhere else on earth. It was my 3rd and best sighting. The first was in November 2011. All my sightings have been in Palm Grove.
From now on the plan is for the Pancam to be in my pocket when I take my morning walk, although opportunities will be restricted because it is the beginning of Winter. Today I filmed a very small moth on the garage. I would not have bothered to film it with my Sony camera. I also took a photo of the moth which filled the monitor. Taking photos (10 megapixels) is a new departure for me. It is so easy. Later I filmed a caterpillar on a fence and some mature and immature Shield Bugs of a type I had never seen before, on and near the trunk of a cycad in Driscoll Lane. Checking the footage this afternoon, I was impressed with the clarity and brightness of the images which are in full HD, ie 1920×1080, whereas the Sony films in 1440×1080 and cost nearly $6,000 in 2007. I returned to the cycad later in the morning with my Sony and tripod and filmed the Shield Bugs with the benefit of a dedicated view finder.
