44 BRITISH BUTTERFLIES.

 in the choice of their favourite haunts. Often have I 

 been disappointed in this way, finding a delicious spot; 

 basking in sunshine, and bedight with all manner oi 

 flcwers such as a butterfly loves, yet with scarcely a 

 stray butterfly to enliven it; while, on the other hand, 

 a piece of the most unpromising flat waste land will 

 be all alive with insect beauty. Those, for example,

It is, in fact, very hard to say what influences bring 

 a swarm of butterflies together, to populate one parti- 

 cular spot, to the utter neglect of others close at hand, 

 and, to all appearance, just as eligible. 



Some species are most remarkable for their excessive 

 localness (as it is called), or, limiting their range to an ex- 

 ceedingly small circumscribed space ; so much so, that 

 some rare species have been known to haunt just one

 endowed so pre-eminently with locomotive powers as 

 butterflies are. 



The local nature of his game should, however, induce 

 the collector to leave no nook or corner unexplored
