This I find interesting
For years I have had Sawfly larvae - Croesus septentrionalis in the garden and at one time or other recorded the egg laying, hatching larvae and the larvae at various stages. But this is the first time I have ever come across a shed skin
I was pretty pleased and posted the image on Friday and thought no more about it. Then it dawned on me that the larvae which had recently shed its skin has a different colour head. All the other larvae I see had a black head but this one doesn't although the black head bit is very noticable on the skin.
Is this usual when larve go through the instar stages?
1. A larva which has just shed the skin with a green head.
2. Larvae of the same species with black heads.(no clearasil jokes
