Leafy hideaways: night time is the right time to see these shy tree spiders.


Near the edge of bushland in Coopers Plains one night last week, I found a lovely, shy pale-backed orbweaver (Araneus albidus) in a bloodwood tree. It had a beautifully constructed retreat inside the curled-up but living leaves of the tree. Adjacent to this dwelling was its prey capture web, a small, well-made orb amongst the foliage. I imagine that when the bloodwood flowers profusely (and it’s always profusely when it comes to bloodwoods), the web must offer a huge bounty of nectivorous insects as food.


To my eye, this spider is virtually indistinguishable from another orb-weaver, the leaf-curling Araneus dimidiatus. That spider, however, only ever seems to use a dead leaf as its retreat, unlike A. albidus. Reading various resources about these two spiders confirms this observation, and it appears to be the easiest way to tell them apart.


On the finer branch ends of many shrubs in the bushland were messy webs with tiny spiders in them. They all had a similar hunched shape, and when I found a slightly bigger example of one of them (around 5 or 6mm), I took a decent enough photo. Identifying it later in my field guide, I found it to be a spider from the Uloboridae family, which are unusual in the spider world for being totally venomless.


The species is likely to be Philoponella variabilis, a common but overlooked spider throughout Brisbane according to Robert Whyte’s website.

  1. Not a great fan of spiders especially the poisonous ones in Australia but your photographs are very good. I also enjoyed you previous post of your camping adventures and see a lot of the critters I have come across when visiting Queensland where my daughter lives with her family. Stay safe and have a great week ahead.

Suburb Guide: Lawnton

Fan-tailed cuckoos are most often seen on a low branch, keeping an eye-out for caterpillars below. Straddling the lush banks of the North Pine River, Lawnton is a suburb of Moreton Bay Regional Council steeped in history . Originally inhabited by the Turrbal people, the land would have been cloaked for many hundreds of thousands of years by a lowland rainforest ecosystem, featuring the hoop pine (Araucaria cunninghamii) for which the river is named after. Unfortunately, the rich soils allowing the vegetation to thrive also made the place attractive to European settlers that wished to farm the land, leading to great conflict with the Indigenous inhabitants. This was eased temporarily by local pioneering figure Tom Petrie, who had lived with and forged a respectful relationship with the Turrbal people, including Dalaipi, leader of the North Pine tribe. By 1858, however, the Aboriginal people of the area were removed and sent to live in isolated reserves around South-east Queenslan

Tadpoles of South-eastern Australia: A Guide With Keys

Book review Reed New Holland Publishing, 2002. It’s noon on a warm autumn day and I am driving south along Beaudesert Road towards the peripheral suburbs of Brisbane’s southside that remain largely a mystery to me. I have decided that not knowing the amphibian fauna inhabiting the suburb of Algester is a personal error that I simply must rectify. My favourite way to search for frogs is to go spotlighting on humid spring and summer nights, but I have left it a little late this year and doubt my chances at finding them now that the evenings have mercifully turned cooler. Instead, I am going to survey the local amphibian population in a way that is quite new to me, aided by a secret weapon sitting in the passenger seat next to me: Marion Anstis’s book, Tadpoles of South-eastern Australia: A Guide With Keys .

Wild Plants of Ipswich

I've never really taken much notice of plants until recently, regarding them usually as just the thing that a bird perches on while you're watching it. This week I decided it was time to change that attitude by trying my hand at plant identification in Denmark Hill Conservation Park, located in the centre of Ipswich. The park is just 11.5 hectares in size, but preserves a patch of bushland that acts as an 'island refuge' in a sea of suburbia. I did my best to focus on the trees and not be too distracted by birds or the resident Koala   (Phascolarctos cinereus)  population, and came up with nine interesting trees and plants seen on the Water Tower Circuit.
