Ghost Moth

Dear Bugger,
Taxonomically, your three creatures are in three different insect orders, which screws around with our method of archiving postings, however, they are significant in that all three appeared in one night, so we are making an exception and keeping the posting intact.  Your moth that is on the shoe is a Ghost Moth in the family Cossidae, and they are also called Goat Moths, Carpenter Moths or Wood Moths according to the Butterfly House website.  The larvae are called Witchety Grubs.  We just posted a letter yesterday with seven awesome images of a mating pair of Ghost Moths, so it would seem they are currently in season in Australia.

Poinciana Longicorn

We are nearly certain that your beetle is a Poinciana Longicorn, Agrianome spinicollis, and the larva is another wood boring grub.  The photo from the Agriculture of Western Australia website is a match.  The Queensland Museum website states:  “This species is found in rainforest and open forest in eastern Australia. It is common in Queensland and New South Wales and also occurs on Lord Howe Island. The larvae are huge white grubs found in rotten wood, especially dead Poinciana or fig trees. It is an important pest of pecan trees. The large adults sometimes blunder into house lights.  Identification  Length 60 mm. This is a very large, broad longhorned beetle with khaki wing-covers and a reddish-brown thorax edged with a row of pointed ‘teeth’. The antennae are a little longer than the body.”
Your final insect is some species of Antlion in the family Myrmeleontidae and you can see some examples on the Brisbane Insect website.  We believe it is most likely Heoclisis fundata which is pictured on Dave’s Garden.
