104 INJURIES FROM BUTTERFLIES. 



The larvae of the Papilio rapes are often found 

 insinuated into the bosom of the flowers of cauli- 

 flowers. 



The caterpillar of the Hawthorn Butterfly (Papilio 

 cratcBgi of Linnaeus) was very destructive to the 

 foliage of fruit trees, in some parts of Germany, in 

 the year 1791.* 



Dr Bright, in passing through the district of 

 Kormond, in Lower Hungary, says, " I observed an 

 extensive forest of oak, apparently six weeks later in 

 its vegetation than any we had passed. On inquiry, 

 it appeared that it arose from the ravages of a destruc- 

 tive species of caterpillar (probably that of the Papilio 

 betulte} stripping the whole forest of its leaves ; 

 which, the peasants told me, was here no uncommon 

 occurrence. I find agricultural writers in Transyl- 

 vania speaking frequently of this circumstance, and 

 their fruit nurseries, in particular, seem to suffer 

 greatly from these insects."
