Clouded yellow?

Spotted this in Andalucia, South Spain, and was wondering if you can tell from this pic if it is a clouded yellow as opposed to a Berger's Clouded yellow (both are present here). In flight it appeared to me that the wings had orange to them and this photo seems to show the deep lemony colour of the clouded yellow, but I can't be 100% sure. It was spotted on a bramble bush in scrubland. Thanks in advance,

    To be honest you will never know unless you have raised the adult from a caterpillar, and they are very different,

    the genitalia are also different but I only photograph them  Sources suggest the front wings are more rounded but having photographed over 400 I still can not find a variance and as far as I am concerned never seen one

    Re: Clouded yellow?

    I have seen many clouded yellows in Andalucia and they all appear to be strongly orange.  Collins show Bergers to be lemon yellow in the male and almost white in the female. It also shows ovoid spots on the black edges of the upper forewing.  These are not present in the male C. crocea.. Lafranchis shows male C. crocea having thin yellow lines in the black uf wing tips cf. spots in C.alfacariensis.

    The problem always seems to be that getting a photo with the wings open is difficult.  You may have to try and catch a couple and get them to open up>

    It's a male Colias crocea, without possibility of doubt.
