BUTTERFLIES AND MOTHS. 183 



terfly of rather depraved tastes, as proved by the 

 fact that swine's dung, dead stoats, and such un- 

 savoury odours have proved the best means of luring 

 them to their destruction. 



The White Admiral, although a woodland species, 

 is certainly local, and is confined to the southern 

 portion of England. The tortoiseshells, and allied 

 species, are usually met with outside the woods, and 

 not in the woods themselves. 



Perhaps the most decidedly woodland species are 

 the Fritiliaries. The large Silver-washed Fritillary 1 is 

 to be seen in extensive woods, and seems to be fond 

 of hovering about the blossoms of the bramble. The 

 Pearl-bordered Fritillary, or Euphrosyne^ is not an 

 uncommon woodland butterfly, and in some woods is 

 found in considerable numbers in May and June. 

 The small pearl-bordered (Selene) is much less com- 

 mon, although it affects similar localities. Finally, 

 the Heath Fritillary occurs in open places in woods, 

 as well as on heaths, especially if heather be found 

 there. 



But wherefore " Fritiliaries " ? This group of but- 

 terflies is distinguished by the silvery spots and streaks 

 with which the under side of the hind wings is 

 adorned ; while the upper surface is marked or 

 chequered with black on a ground colour of golden- 

 brown, and in this device they obscurely resemble the 

 old-fashioned liliaceous flowers called " Fritillary/ 7 

 whence it is conjectured that the name of the insects 

 has been derived. The caterpillars are cylindrical
