Caterpillar ID from the South of France

[Chris Jackson]

Hi Folks,
I need an ID for this cat.
Seen today in the South of France on the plant Buckler's Mustard (Biscutella laevigata).
ID ?

Thanks.

I'd suggest Euchloe crameri. I think that was probably high on your list too ... What else did you have in mind?

Thanks Guy,
A. euphenoides down here is a possibilty.

In the book by T. Lafranchis there are some very nice photos of the cats of both species, but my eye is not sufficiently tuned to differentiate between the 2.

In my books euphenoides has a much stronger white band - but I imagine this is quite an early instar and these are not always the same as the later instars shown in the books.

For those who don't know, in the South of France, Biscutella laevigata is host plant for E. crameri and A. euphenoides and their cats can coincide and overlap.

Thanks Guy,
Looking through my archives, I have found these 2 photos of the same cat.
This cat has a yellow dorsal stripe and may well be A. euphenoides:

Side view of the same cat:

And you would be right about the stronger white band.

Whereas my cat from yesterday clearly has a grey dorsal stripe, which I'll put down as E. crameri:

Cheers,
Chris
