Flapping profusely but not flying then still like statue when placed on tree, camoflaged as bark. Intermittently flapping wings like crazy, presumably spreading pheromones. Joined by slightly smaller male.
Thanks for confirming, I have placed her on wattle tree. I cannot see the male anymore. I never saw her fly. She was crawling on the ground at the flyscreen door, perhaps moving towards the light inside, although there were lots of streetlighting outside and waning gibbous moon. Maybe looking for something to climb up to gain height. If I understand correctly the females lay under bark on wattle tree and then the caterpillers burrow into tree and down to roots, so food is mix of bark, plus what tree produces to heal wound, plus roots? I was checking out the butterflyhouse info. Does the Endoxyla lituratus not have any blue on thorax?
There are drawings by Herrich-Schäffer (1855) of the of the two species at https://archive.org/details/sammlungneuerode01herr/page/n204/mode/1up There : only the male of E. encalypti is shown as having the blue border to the thorax. Evidently females can also have a blue border, although the appendage shown at the tip of the female abdomen does look like a phallus. I wonder if Herrich-Schäffer got the drawing numbers confused.
Thanks. I suppose individuals can vary? Both male & female in this pair certainly have blue border to the thorax. I have some close up images of male just after mating that clearly show the blue and the 'mouse eyes', but looks like I've reached max capacity on adding any more images to this post.
Here are images of male, https://canberra.naturemapr.org/sightings/4640910. Sorry I didn't get images of those parts, their wings were in the way. I assumed female was the larger one I placed on tree and the male was the one who flew over to her for mating, but that's just an assumption. I didn't want to disturb them, but I wished I had better images. I couldn't tell if female was laying eggs on Eucalyptus or Wattle, as I never saw oviposiror. Do you happen to know the timeframe between mating and egg laying? Thanks.
