NATURAL ENEMIES.

like brown or blackish worms (^Filaria)^ resembling in ap¬ 
pearance those called horse-hair eels (^Gordius'). I ha^'e 
taken three or four of these animals out of the body of a 
single locust. They are also much infested by little red 
mites, belonging apparently to the genus Ocypete; these so 
much weaken the insects, by sucking the juices fi'om their 
bodies, as to hasten their death. Ten or a dozen of these 
mites will frequently be found pertinaciously adhering to the 
body of a locust, beneath its wing-covers and wings. A kind 
of sand-wasp preys upon grasshoppers, and provisions her 
nest with them. j\Iany birds devour them, particularly our 
domestic fowls, which eat great numbers of grasshoppers, lo¬ 
custs, and even crickets. Young turkeys, if allowed to go at 
large during the summer, derive nearly the whole of their 
subsistence from these insects.
