Alan writes, "Caligula zuleika are perforated like C. thibeta, etc., – but they are very tough cocoons. I am told that both species (zuleika and anna) overwinter in this stage."

Alan Marson writes, "As promised here are the images for Caligula/Rinaca zuleika. The stock was from Yunnan, China and they are feeding on Alnus. I started them on Viburnum, Cornus and Alnus – but switched them all to Alnus in L2 when I found that it was the native foodplant in Yunnan. Apparently this species and C anna overwinter as cocoons."
