Please can someone help me identify this caterpillar. I found it in a bag in my green house.
Has anyone been able to identify this?? I still don't know what it is..
This looks very much like Red Underwing Caterpillar (Catocala nupta), They are large moths with quite plain patterns on the wings of the adults but brilliant Red underwings. Very nice find!
This link has it but you need to look under 'Red Underwing' as you can't link to just one page.
Uk Leps - A site that has loads of moth and butterfly eggs, larvea, and pupa photos for IDing.
I should add, considering where you found it, I would suggest that is was looking for a place to pupate.
I hope this helps
Thank you so much Crystal you have made my day!! I am so pleased I am now able to identify it and learn about a new moth! :)
