The Wood White Butterfly is common throughout a great part 

 of Northern and Western Asia, and is in many localities very 

 abundant; but in North-western Europe, including England, 

 Wales, and Ireland, it is extremely local, and has disappeared 

 from many localities where it was formerly found ; in Scotland 

 it is unknown. It has a low weak flight about bushes and 

 open places in woods, but rarely strays far from the shelter of 

 the trees. It is double-brooded, appearing from May to

 The wings are of a milky-white above, with an ash-coloured 

 blotch at the tip of the fore-wings ; on the under surface, the tip of 

 the fore-wings and the under side of the hind-wings are greenish, 

 mixed with scattered black scales. The whitest specimens are
