Baltimore (Euphydryas Phaeton) searches the 

 swamps for the snake-head, and lays upon the 

 under surface of the broad 

 leaf a mass of hundreds of 

 eggs [see Fig. 15], piled in 

 several layers. Our Nettle 

 Tortoise-shell (Aglais Mil- 

 berti) lays its eggs upon the 

 under surface of the leaves 

 of nettles, generally be- 

 tween the principal veins, 

 but often covering some of 

 these, in large, irregular, 

 partly open patches, in 

 which the eggs are rarely 

 if ever piled upon one an- 

 other [Fig. 82] ; sometimes 

 several patches may be 

 found upon the same leaf. The Blue Swallow- 

 tail (Laertias Philenor), partial to 

 aristolochia, fastens on that plant 

 and its allies some six or eight eggs 

 side by side in two or three short 

 rows ; and I have twice found upon 

 the under surface of nettle-leaves a 

 hanging column of from three to nine 

 glistening eggs of the Orange Com- 

 ma (Polygonia Comma) placed end to end [Fig. 

 83]. The Banded Purple (Basilarchia Arthemis)
