4th instar

Deep in a Swiss forest, at least one caterpillar has graduated to 4th instar. All the others I have found are still 3rd instar. Here is Kisāgotamī:

Her discarded skin can be seen at her tail. She is still small but will now grow fast before moulting again in about two weeks into her final larval stage.

Both these pictures were taken in the early evening, after the sun had set.
