Comments from Martin Lagerwey: one nymph molting, the emerging nymph will be second instar and is entirely red for a few hours till its black markings appear. This group is a stink bug. I think it is the predatory stink bug based on the 'eyelashes' seen on the eggs. Two photos included with this observation.
This female has laid eggs on her coccoon. The caterpillars will hatch and eat the coccoon first and then either stay on the plant that the female made her coccoon on if it is to their taste, or try thier luck and balloon to wherever the wind takes them. The female dies shortly after laying her eggs. We had masses of these caterpillars feeding on the Indigofera australis in our front yard during 2014 and 2015.
Some noisy minors harassing a nest hollow about 60cm off the ground attracted my attention. On inspection a small speckled grey 'hawk-like' bird (approx 20cm) flew out and was chased by a minor who plucked a few feathers most likely from it's tail (see other photo). It all happened too fast for a photo! 3 eggs in the nest which was lined with leaves and some grass.
These eggs were identified by Ken Walker as being those of Tettigoniidae spp. I did bring them inside a day or so after these photos were taken, but the only thing that hatched out of them then were two tiny wasps. I think that some had already hatched when I brought the leaf inside.
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.
These ten tiny green eggs were laid on an outdoor table, under a hat. Ten days later, ten tiny bugs emerged. Two days later they had left to find their way in the world. Order: Hemiptera. I think they are Family: Pentatomidae.
