Mont Ventoux Provence in France April 20th -28th

[luehdorfia]

I will be on holidays at the Mont Ventoux end of April, and wanted to know if anyone knows some good locations for early spring species?

It should be the right time for Anthocharis euphenoides, Melitaea deione and hopefully also Zerynthia rumina. I would really appreciate any hints, also what other species might be interesting during that time?
Iphiclides podalirius is for sure also already on the wing.

Month Ventoux has a sunny South side and a colder North side. You can find lots of spring species from early in the year (South Side) until very late (June, North Side, i.e. Anthocharis cardamines). I remember lots of worn Iphiclides in early June on the South slope in the fields next to the last town before going up hill.
