Excellent photos of a stunning lep. I am a bit confused by this. Yes it does rather look like Dysphania numana but there are some problems. None I have seen online have the dark blue head and shoulders, they are all fluffy yellow or orange. Even dead or battered specimens. Also they have a row of yellow spots adjacent to the termen on the underside of the hindwings but none seem to have the other large yellow patch on the underside of hindwing. e.g. https://inaturalist.ala.org.au/observations/219065312 https://inaturalist.ala.org.au/observations/217215559 Puzzling This is a pair in cop so the big yellow patch is not a gender thing https://inaturalist.ala.org.au/observations/239073783
D. sp is probably the solution. D. numana is the only sp I can find listed for Aust, which I don't think this fits. There are at least 19 sp through island countries N of Aust and Asia see https://www.inaturalist.org/observations?taxon_id=52021&view=species none of which look exactly like this moth. This is a very interesting record.
I think this mighjt match the Andaman False Tiger Moth, suggesting it may be a vagrant to Northern Australai. https://www.inaturalist.org/taxa/1229066-Dysphania-andamana/browse_photos?grouping=taxon_id&place_id=6744 Blown in from Andaman Island by a recent cyclone perhaps?
Thank you for the discussion. Itโs a bit disappointing after all of that to only get a genus and not a species. ๐ itโs fun to challenge the experts.
Most of the 10,000 or so named Australian moth species were named and described between 1850 -1950 and are those most commonly encountered, but it is now evident that there.are probably as many again, rather rarer, unnamed. Yours seems to be one of those. Do not be dismayed. Yours is rarer than the named moths. Be thrilled.
