I took this picture 5 months ago. The moth in this picture is alive, but pretending to be dead, and was later released back outside after she (I assume this is a female) got loose in my house. This is the only picture I have of this.

So, you assumed it is an ovipositor because you assumed it was female??

Have a look here: https://www.researchgate.net/publication/319332183_A_review_of_the_occurrence_and_diversity_of_the_sphragis_in_butterflies_Lepidoptera_Papilionoidea
If it is a female, does it possible that you observe a kind of sphragis or similar structure?
