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.

By-catch

The stick insect climbs onto Terry's hat

When mist-netting birds last weekend I came across this little beauty in one of the nets:

A Pink-winged Phasma Podacanthus typhon.

After I safely took her out of the net and we took a look at her, she instinctively climbed up whatever was near, in this case it was Terry. Then once she had explored around his hat and could not climb any farther, and had not found any green foliage to hide in, she opened her wings and flew off. And what marvelous wings she had - bright pink, wow!

It looked like she was a female as her abdomen was swollen, perhaps gravid. She can lay eggs without mating, by parthenogenesis, and if she does so, the offspring wold be all female. If she did mate the sexes would be mixed.

She merged well with eucalypt leaves
