Field Notes

Description:

This attractive little bug was sitting on a broken branch stump on a large barkless eucalyptus log - the only place that could match it's appearance. About 16mm long with etched black body and a perimeter of pale copper colour. Banding on antennae. I loved the way it found the best possible place to camouflage itself.

Habitat:

Within a nature reserve incorporating stringybark, acacias, pomaderris, pittosporum, assorted woody shrubs and grasses.

order: HEMIPTERA 
suborder: HETEROPTERA

I think the Morwell one might work if we say it's a previous instar to this one? The wing buds are shorter than here. I do like the antenna segments and bands and bands on legs... ?

This has advanced wing buds and looks like the penultimate molt. I suspect notius depressus which you have already seen a newly eclosed one which was still pink. Here are two references showing nymphs and the morwell one does cast some doubt about my inference. http://www.projectnoah.org/spottings/8951316 http://morwellnp.pangaean.net/cgi-bin/show_species.cgi?find_this=Notius%20depressus&image_letter=d&show_image=../images/full_size/Notius_depressus_d&show_date=2007-07-11&show_caption=Immature%20Notius%20depressus%20stink%20bug%20by%20the%20Weir%20Track
