DRONE-FLIES. 

 (ERISTALIS TENAX.) 



L 



compassion has 

 often been stirred 

 in autumn as I 

 watched the num- 

 ber of unhappy drone-flies 

 buzzing on the window-panes, day 



f after day, until they perished from 

 cold and hunger. These flies closely 

 resemble the real drones, which are 

 the males of the honey-bee and have four wings, 

 while these, being flies, have but two.
