206 JUNGLE PEACE 



rain of the night, and all faced northeast — ^the 

 certain direction of both rain and wind. 



The first one or two roosting butterflies I 

 thought must be due to accidental association, 

 but I soon saw my error. I counted twelve of 

 the Red-spots and eight Yellows on two small 

 bushes and a few minutes' search revealed forty- 

 three more. All were swung invariably from 

 the tips of bare twigs, and there was very evi- 

 dent segregation of the two kinds, one on each 

 side of the glade. 



When I disturbed them, they flew up in a 

 colorful flurry, flapped about for a minute or 

 less and returned, each to its particular perch. 

 After two or three gentle waves of the wings 

 and a momentary shifting of feet they settled 

 again to perfect rest. This persistent choice of 

 position was invariably the case, as I observed 

 in a number of butterflies which had recogniz- 

 able tears in their wings. No matter how often 

 they were disturbed they never made a mistake 

 in the number of their cabin. A certain sec- 

 tion of a particular twig on a definite branch 

 was the resting place of some one heliconia, and 

 he always claimed it. 



Several were bright and fresh, newly emerged.
