The Clouded Yellow Butterfly measures from 1-/1 to upwards 

 of 2 inches across the wings, which are of a rich chrome-yellow 

 above, sometimes nearly orange, and occasionally with a slight 

 purple flush. There is a broad black border (broadest at the 

 tip of the fore-wings), which is veined in the male and spotted 

 in the female with sulphur-yellow ; at the end of the cell is a 

 round black spot. The hind-wings are sometimes more or less 

 dusky, especially in the female ; there is a large reddish-yellow 

 spot at the end of the cell, and in the female, the black border, 

 which hardly extends to the anal angle, is more or less spotted 

 on the inner side with yellow. The fringes of the wings, as 

 well as the antennae, are rose-colour. On the under side, the 

 fore-wings are paler, with the black spot reproduced, and a more 

 or less distinct row of black spots on the disc ; the tip is greenish. 

 The hind-wings are green, with a central silvery spot, surrounded 

 with rusty red, and a smaller one adjoining; there is also a 

 row of rose-coloured dots on the disc. 



This insect is extremely variable, and some of its numerous 

 varieties have been mistaken for the East European species, 

 E. chrysotheme and E. niyrmidone (Esper), which could not 

 reasonably be expected to be found in England at all. There 

 is a pale greenish-white form of the female, which is sometimes
