Can you please ID this moth. She came in on Nov 1st, laid her eggs on the back of my chair then stayed till she died 5 days later, sad.But what is she?
We strongly feel this is a Hawkmoth in the family Spingidae, however a species identification is eluding us. We started searching Butterfly House, and the two best candidates there are the Australian Privet Hawkmoth, Psilogramma casuarinae, and Synoecha marmorata. The former has the dark markings on the thorax, and the latter has closer wing markings. Csiro has this image of the latter. The Sphingidae of the Eastern Palaearctic website has this to say about Psilogramma increta: “Reliably recorded from northeastern China, Japan and Korea, south and east through China, Taiwan, Vietnam, Thailand, the Philippines and Peninsular Malaysia, to the Greater Sunda Islands; then west through Burma/Myanmar, Nepal and India to Kashmir. It is possible that P. increta extends much further east through the Malay Archipelago and may even reach Australia and the Pacific islands. However, in these latter areas, the features of adult wing colour and pattern that farther west differentiate P. increta from the closely related species, P. menephron, break down and it becomes impossible to reliably distinguish them on this basis. The two species are also identical in genital structure. Mell (1922b) described diagnostic features of larvae and pupae but these have yet to be investigated in eastern populations of Psilogramma.” Perhaps one of our readers will be able to assist in this difficult identification.
Update and Correction
Thanks to a comment from Ryan, we now realize this Hawkmoth imposter is actually a Wattle Goat Moth, one of the Wood Moths in the family COSSIDAE.
