Guernsey - noted in great abundance during 1943; a very fresh pair of specimens taken when first seen 

 1 5. vii. 1 943, the $ being of var helice; species became abundant in clover and lucerne fields throughout 

 August; many specimens seen in Castel, in fields overlooking Cobo; noted that majority of earlier 

 specimens were S3, by mid-September there was a preponderance of $$; on 23. ix. 1943 \S freshly 

 emerged was taken with wings still moist, this being an exceptionally late emergence, specimens seen

Sark - specimens seen in last week of v. 1947, numbers steadily increasing due to migration from France; noted 

 as abundant on 6.x. 1947, 1 specimen of helice (pallida), C.J. Shayer, 1947a (80):288. 



Guernsey - shortly after a visit to Sark, specimens were seen in various parts of the island, but gradually 

 decreasing in numbers until last week in vii. 1947, when many fresh specimens were observed. Stated 

 that species is subject to sex-linked variation in the $ whereby the normal saffron ground colour is 

 modified to all shades from deep cream, through primrose to white. This normally occurs in the ratio of 

 1-15 and the variety is known as helice. An unprecedented number of aberrations were seen, an 

 aberration taken on 31. vii. 1947 was identified as the true f. helice being deep primrose in colour; 

 specimens of f. pallida frequently seen later in the year. By 7. viii. 1 947 the species was very common; 

 on 8. viii. 1947 a solitary specimen off. pallida was observed; on 14. ix. 1947 a $ of large size, 5-7cm
