Fantastic Phasmid

This Titan Stick Insect Acrophylla titan was in our garden yesterday, he probably still is, but I can't see him. His two long antennae are tucked in between the front legs, which have a ragged, leaf-like form.

The thorax and legs had thorn-like spines which also made him resemble a true twig.

Acrophylla stick insects are well named as they favour the highest foliage of eucalyptus trees to feed on, acro being Greek for highest or topmost. So I don't know why this one was down in at our lowly level. The tall yellow box in the front garden, which spreads over where he was hiding, is about 20 m tall. He was about 20 cm long.

His eyes had cryptic colour bands around them, and there was a tiny mite clambering around them.

Seen from below, his head was just as spectacular, with an intriguing array of mouth parts. Why does a vegetarian need such a complicated eating system, I wonder. They only eat leaves.

His wings are on the last section of the thorax, but extended over the fore part of the abdomen. The vestigial wings on a female only extend as far back as the last pair of legs. Although his wings are small for his size, the males can fly. The females cannot. I think this one must have flown away as I left him in one small tree and after dusk he had gone, not in the tree. And yes I am sure he wasn't there. They are nocturnal feeders.

And look at those fantastic feet. He has two hooks and a gripping pad on each one, so over six legs, that's a lot of sticking ability. No wonder they are such good climbers and like to be high.

Big rain

Droplets of rain hang from eucalyptus flowers in the garden. 

More than 50 mm of rain fell on Canberra yesterday, 29 mm before 0900 hr and final figures not in yet. A great relief after such a long dry winter and spring, but I would rather less fell more frequently to give the land a chance to re-invigorate itself, the plants to grow and animals to prosper. Too much rain at once is of limited good.

During a break between the heaviest downpours, the water clung tight, running slowly down the long tapering leaves.

Eucalyptus bark shines when wet. Many species of eucalypt cast their bark in summer and these had only just begun to do so.

The old bark of this tree has been heavily scratched by possums who climb these trees every night. A new skin is long overdue.

While I was out between showers, I checked the leaves of the silk tree for eggs or small caterpillars of Tailed Emperor butterflies. These magnificent butterflies have laid eggs on, and new adults have successfully flown from this tree in most recent years, so I was anxious that any eggs or caterpillars might have been lost in the torrential rain. No sign, but expect updates to the blog when they do appear.

The flowers on the silk tree had only began to open the day before, and in the rain their finery looked rather bedraggled.

Wet pink fur-balls.
