SEPTEMBER 59 



The feet are armed with two claws, between which is 

 a pad covered with hairs, which secrete a kind of muci- 

 lage, thus enabling the fly to walk with ease on a ceiling. 

 With its claws it can hold to rough surfaces. 



The under lip of the fly makes the thick tongue, whose 

 broad, knoblike end can divide into two flat parts each 

 with a rough surface. Of these we are unpleasantly con- 

 scious when, on hot days, he endeavors to lick up the 

 perspiration.

The eggs are laid in manure and hatch into maggots, 

 footless, worm-like larvae, which after a while wrap them- 

 selves up in a brown case, from which they emerge adult 

 flies. This happens many times during the summer. 

 AYhen winter approaches, a few, by hiding in protected 

 places, manage to survive until spring. 



Mosquitoes : 



These insects belong to the Fly or Two Winged Family 

 (Diptera), but in their life history they more closely re- 

 semble the dragon fly.
