First to second
Acronicta afflicta in molting action.
(these photos are not of the same individual)
1st instar (note how it looks different from when it first hatched – it still has the same head size though!)
In progress… all the caterpillars which were molting were bright white, with almost no green coloration left at all.
And now for something completely diff…. uhh… second instar!
As an aside, their common name is the Afflicted Dagger Moth.
I wonder what they’re afflicted by?
