THE COMBINATION OF MANY METHODS OF 

 DEFENCE 



It has already been shown by repeated examples that, 

 although the various uses of colour are quite distinct 

 from one another, they are frequently combined in a 

 single animal. Thus the larvae of the Elephant Hawk 

 Moths (Chcerocampa elpenor and C, porcellus) were 

 shown to be well concealed among brown leaves ; but 

 they assume a terrifying attitude when detected and 

 attacked. I will now bring forward two striking ex- 

 amples of the different lines of defence which are 

 successively adopted by certain caterpillars. 



The larva of Puss Moth well concealed by General 

 Protective Resemblance 



The larva of the Puss Moth {Cerura vinula) is 

 very common upon poplar and willow. The circular 

 dome-like eggs are laid, either singly or in little groups 

 of two or three, upon the upper side of the leaf, and 

 being of a reddish colour strongly suggest the appear- 

 ance of little galls or the results of some ather injury.
