An altitude butterfly having a minimum altitude range of 1500m in the Alpes, although occurring lower in the Jura. It is similar to the Mountain Clouded Yellow (C. phicomone) although clearly recognisable by the solid black marginal band on the upf which shows through to the underside, especially if the sun is behind it and light is shining through. |
The unh "hollow" cell mark differentiates it from other Crocea species, but I'm not sure how reliable this is. As with many Colias species, the male upperside is yellow and the female white. It is rather localised and I have only seen it in a few locations, and only in 2010 did I see it in more than ones or twos in any location. In 2012 (and subsequently in 2016), however, on a visit to the département of Savoie, palaeno was found to be distinctly more common. |
