Female Commas normally lay there ovum [eggs] on the edge of Nettle leaves and are fairly easy to find but, can be mistaken for a Red Admiral's ovum, [who also lay their ovum on Nettle leaves and, sometimes on the edge of the leaf] as both are very much alike. The contents of the ovum are green when first laid. Then after about 8 days the contents turn a light greenish yellow and eventually you can see the tiny larva through the skin/membrane of the ovum at least 24 hours before the larva emerges, as the membrane/skin of the ovum is transparent. There are 2 broods.

through the transparent membrane/skin of the ovum
On the 13th day, this particular larva emerged, [the time scale for emerging larva does vary].
