Early stage larva ID please

[Chris Jackson]

Hi there,
I would like an opinion on the ID of this larva on Buckler's Mustard (Biscutella Laevigata) in the South of France - 26th April.
It may be the larva of either Provence Orange Tip or Western Dappled White, or, perhaps, something else ?
This is the host plant:

This is the context in the Parc des Bruyères in Marseilles:

Here is the Caterpillar (quite small - possibly 1st or 2nd instar) on the host plant:

Hi Chris,

i would say your larva is a 1st instar Provence Orange-tip, that is very close to it's first moult. I went on a hunch, because the caterpillar looks like a late 1st instar Orange-tip larva and found a picture very similar to your photo on Google.

All the best, Nick.

Thanks, Nick,
Provence OT seems logical to me.
Cheers, Chris
