 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 

 August. 



It measures about an inch and a half across its long and 

 narrow wings, which, together with its slender body, have been 

 thought to give it somewhat the appearance of a Dragon-fly. 

 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 arc
