THE INSECTS OF NEW JERSEY. 8oi 



Family TRYPETID/E. 



The "peacock flies,"' so called because of their habit of elevating the 

 wings and strutting about, peacock like. These wings are often prettily 

 marked and spotted with black or brown. In the female the abdomen 

 is often prolonged into a horny ovipositor. The flies are gracefully built, 

 fly slowly and are noticeable by keeping their wings in constant motion. 

 Most of the members of the series feed in plant tissue of some kind, 

 either in leaves, in stems or in fruits, and a number of them are gall- 

 makers. The only species of economic Importance in this State is the 

 "Apple maggot," which injures some of the early summer varieties. The 

 only remedial measure is the prompt removal and disposal of all fruit 

 from trees known to be infested.
