for by emitting, from every pai't of its body, 
foamy bubbles, refembling fpittle, under 
which it conceals itfelf, the larva is not eafi- 
ly difeovered : but when this froth is remo- 
ved, the larva is found ; but it is foon co- 
vered again, by a frefli emiflion of froth. 
Thus the larva is enabled by nature to pre- 
ferve itfelf againft the injury of the weather, 
and from being dellroyed by other infeds. 
This is another inftance of the variety of 
means adopted by the Creator to preferve the 
balance of all things. As the larva of this 
infeft is liable to be preyed upon by differ- 
ent animals, it is provided with the power 
of emitting this foam, as the only proteftion 
againft its enemies.
