FIRST APPEARANCES OF BIRDS, INSECTS, ETC. 217 



ing directly it is alarmed, which is pretty 

 frequently, and it has something of the erratic 

 flight of Saturnia pavonia. It is a tiresome 

 insect to catch and spends most of the after- 

 noon gambolling round the tops of the birch 

 trees. It certainly feeds most freely in the 

 sunny patches, between 10 and 12, but at 4.30 

 one was feeding at the foot of Dunyeats Hill, 

 and one's best chance is undoubtedly a sunny 

 morning and a nice (not too high) patch of 

 sallow in full bloom. It seems, however, only 

 to be the males which come to the sallow bloom.
