a beautiful butterfly is pulling something out of its rectum

good night steemit friends all, today i will post a butterfly photo that has a beautiful color and is pulling something out of his rectum, i photograph this morning. This morning I went looking for some photos for me to post in steemit, and this morning I chose to go to the gardens that were around my residence, vigorously when I got to the garden, I tried to observe some animals for my photos, and I happened to see a butterfly emitting from the rectum, which made me interested in photographing this butterfly because it was the first time I had found a butterfly that was pulling something out of its rectum. if one of the friends of the stemit knows that what this butterfly is emitting from the anus. I really hope once you can comment on my post. and you can see clearly on the pictures I've posted.
