An oval shaped open-weave cocoon made from the hairs of a very hairy caterpillar. After the wingless female moth has pupated she emerged to lay her tiny, pearly eggs all over the matrix. The remains of the pupal sheath can be seen within the cocoon. The whole structure is about 25mm long. The last pic is 2 days later and shows her up on the cage, face down, abdomen up. The abdomen was slowly waving in the air.
This caterpillar was very well camouflaged in acacia leaves. I found it after noticing frass and working out where it was coming from... right in front of me!
About 40mm long, a real Aussie in vivid green with yellow/gold flecks throughout. Only one set of prolegs and claspers says geometridae. http://lepidoptera.butterflyhouse.com.au/enno/senilis.html
A tricky little spider which I only noticed when it moved onto a green stem from a grey one. Strongly resembling a broken twig node it was about 8mm across it's body.
On twigs of Acacia mearnsii.
These were low growing from two oval shaped leaves up to about 70mm above the ground and about 40mm wide. Roughly half a dozen calli occur in the rear part of the labellum plus a single taller stalked callus standing in the back. The calli decrease in size to the front. The orchids dupe male Thynnus sp. (flower wasps) by producing the 'scent' of a female wasp. The flower has a large labellum including a group of dark, shiny calli (stemmed knobs and buttons) with a particular 'insectiform' arrangement. The broader callus at the centre is what the male wasp grasps at causing the labellum to collapse upwards. The wasp’s thorax is then coated with pollen as it fights it's way out.
Strange little cases built with three offset chambers. About 12mm long overall. Several were found on a single callistemon plant always about midway on a stem. This is Tortricidae, Olethreutinae, Eucosmini, Spilonota sp.
