Black swallowtail, collage of metamorphosis, 3 stages - Papilio polyxenes - Male
Roswell, Fulton County, Georgia, USA
The first image was taken on June 22; the pupa formed July 2; and the butterfly emerged on July 12, 2005

Black Swallowtail from Pupa to Butterfly
The description says Pupa to Butterfly is 10 days.

Watching a few newly formed Pupa. Is 10days normal time?

Pupa were formed on 9/1/22 to 9/6/22 and curious if I can expect them to hatch or overwinter as Pupa.

Would appreciate any input you may have.


pupa to butterfly
I'm sorry, Tom, but I'm not an expert. All I know is back when I created this mosaic from photos taken on the progressive days is that it was 10 days from pupa to butterfly in July. I cannot advise regarding whether your pupa will hatch before winter or will overwinter. Sorry.

Moved from Black Swallowtail.

Thanks, David.

Used glossary
This is used on the metamorphosis entry in the glossary--a really nice addition, thanks!

I'm honored. Thank you.

Interestingly enough, on this very day, I coincidentally posted this same image to a thread on a Flickr group I co-administer called Super Eco. The thread discusses home gardening:

Very nice,
and it looks like a male.

Yes, it's a male. The spotbands on male Black swallowtails are wider than those on the females.
