In the "flat-footed flies" the posterior tarsi are broad and 

 flattened, especially in the males. The wings are propor- 

 tionately large. They are quick little flies and are often 

 seen darting around on leaves, active in the shade and at 

 times seen hovering over foliage about sundown. The larvae 

 live in mushrooms and other fungi.
