A couple of things are worth mentioning, here: Firstly, sawfly larvae (in common with moth and butterfly larvae) go through a series of skin moults, after which they may change colour. These different colour forms are called 'instars'. The instars may vary in colour and/or in pattern, leading to some difficulty in identification, since all instars need to be known for a positive identification in each case. Some of the sawfly larvae in the above image have just started to eat and have turned green, the expected 1st instar colour for this species. The larvae which have eaten only the eggshells are still pale and are really instar 0 larvae.
Also note the marks (top left) where the eggs were attached. These indentations are used to anchor the eggs, and are made by the modified ovipositor, or saw, of the female, which gives rise to the name 'Sawfly'.
Despite the more-or-less continuous rain, a few moth species are still coming to light.
This is Lesser Yellow Underwing - Noctua comes - and is new to me.
And this is Dark Marbled Carpet, which I see every year.
