More pictures:  The perfect disguise!


The Clouded Yellow always settles with its wings closed and the greenish yellow undersides provide excellent camouflage......if it lands amongst vegetation and you take your eyes away you may never see the butterfly again until it flies away (click on 'the perfect disguise' above!) The orangey-yellow uppersides are very conspicuous during the flight which is very rapid. When at rest the dark borders of the uppersides show through on both wings and thus females can be instantly recognised as there are yellow spots within. Some females are off-white rather than yellow (form helice) and are encountered rather irregularly. One adult female was observed in mid-December 2002.
