I in Eye -Jaclynne Cain, here is your spotting, http://www.projectnoah.org/spottings/826...
Are you talking about this?
Perhaps your spotting is not the larva of Pachliopta aristolochiae; larva of Pachliopta aristolochiae should be black in color and with a white band. If you wish to check it, you can follow the link to Wikipedia. :)
SandiSawyerr, yea, I was stunned when I looked at this picture! When it flies fast under sunlight, the fast-moving shiny neon blue color makes it like electricity flowing through the air! Therefore, it has a Chinese common name called 電蛺蝶, which means "Electric butterfly".
Sorry that I haven't done any measurement with this butterfly, I have checked the field guide, It has a wingspan of about 70mm, hope this information helps~ :)
