ERISTALIS Latr. 



E. tenax Linn. This is the common "drone" or "chrysanthemum fly," 

 which occurs throughout the State until late fall, and is said to 

 pollenize chrysanthemums. It resembles a honey bee so closely that 

 most persons decline to handle it, therefore it is also called "drone- 

 fly." Its larva lives in the foulest excrement, and is a typical rat- 

 tailed maggot.
