The Crescent Pea Moth {GraphoUtha dorsana).

 Covered with brownish-yellow warts. Habits : The 

 moths fly about in large numbers round the pea 

 blossoms, always a short time after sunset. The 

 female lays one, two, or at most three eggs, on a very 

 young pod, or on an ovary. In fourteen days the

 the peas. The opening made in the margin of the 

 pod closes up again. The pod generally ripens early. 

 When it opens, the full-grown caterpillars creep out.
