Caterpillar ID please

[zigzag_wanderer]

Hi all,

Saw these on my walk round my local fields this evening.

They were under a leaf of a relatively small oak tree. Very small and looked fresh out.

Assume must be a very common moth.

Thanks as always for any ID help.

And if you'll kindly allow me to throw in a supplementary question.

This spider had caught a pair of tasty treats in the same field.

Almost dragonfly-like markings on its back.

Anyone know this one ? I think it's too early for a type of Garden Spider ?

(Both seen this evening, I'm in mid Sussex)

Your caterpillars would eventually turn into Buff Tip moths

Many thanks for that Trev !
