Ichneumon wasp female about 25mm body length with a fairly short ovipositor (compared to others in this genus)
She came to rest on our outside night last night offering a lovely semi-translucent view of her parts. Outer urban back yard.
As genus Netelia her young would be external parasites of sawfly larvae or moth caterpillars. She may have been drawn to the moth activity around the light rather than the light itself.. then found it nice and warm.
Some general good icky info from the Australian Museum...
"Ichneumonid wasps have long antennae with 16 or more segments, whereas most other wasps have 13 or less. Some female ichneumonid wasps have a very long ovipositor (a tube-like structure for laying eggs) which is used to reach insect larvae such as wood grubs which burrow in bark and wood. This is a modification of the sting that is present in other wasps, so most ichneumonid wasps cannot sting humans, with the exception of the larger orange species in the subfamily Ophioninae. Wasps in the family Ichneumonidae are superficially similar to the related family Braconidae, but ichneumonids are usually larger insects, and differ in details such as the pattern of wing veins and the structure of the abdomen."
