What is this butterfly doing? (1 Viewer)

[Hulio]

I filmed this butterfly in a butterfly garden a few weeks ago and I am wondering if anyone can tell me what it is doing with its abdomen in the first clip of it. Was this an unsuccessful attempt to lay an egg? Or to defecate? It doesn't appear that anything was left behind on the leaf.

I do apologize for the intro and outro in the video. It's such a short clip, that I may not even make this video listed to the public. In the meantime, I am curious as to what the butterfly was doing.

Thanks in advance for any help!

I've received an answer and it likely was an attempt to lay an egg.
