The lace-winced Flies are very common insects throughout the 

 summer months upon herbage and the foliage of trees. They 

 usually of a light green color or yellowish. While alive tin 



very bright ; and on this account they have also n the 



popular name of Golden-eyed Flies. Some species, when handled, 

 emit a very disagreeable odor. A remarkable fact in the hi 

 these' insects is the way in which the female cares for h< 

 When about to lay an egg she emits from the end of her body a 

 minute drop of a tenacious substance; this is drawn out into a 

 slender thread by lifting the abdomen ; then an egg N placed >n the 

 summit of this thread. The thread dries at once and firmly holds 

 the egg in mid-air. These threads are usually 10 to 15 mm. (0.4 to O.6 

 inch) in length, and occur singly or in groups It jx probable that 

 this placing of the eggs on stalks protects them from th< 



'us insects, including the aphis-lions themselves. When 

 ; phis-lion hatches it crawls down the thread that held up the 

 . and starts in quest of some small insect or egg which it 

 1 upon. While doing so it may wander through a forest of < 

 stalks, not observing the eggs far above it. The !.; 'lie- 



form, and have long, sickle-shaped mandibles. The) feed elm ily on

of dense lay k. In order to emerge the insect cu: ular
