HELP, Glow Moths???

I talked to the spider. She winked at me. I left and found the empty bottle. I went back to the spider, she winked at me this time too. So I went back to the glow moths, it wont let me catch them. I went back to the spider, she winked at me. I can not get her to ask me for glow moths. She has 1 glow moth in her cave already. Please am I missing something???

I figured it out! It was because I hadn't talked to Lenora (I think that was her name) and gotten the get her silk quest. I was so confused. I have beaten this game before but it's been a couple years ago so I don't remember all the details.
