INSECT INTRUDERS. 



August, the latter part of September and 

 about the middle or 3rd week in October. 

 When the caterpillars are full grown, each 

 spins a small cocoon, attaching it to the 

 shoot or leaf stalk by means of a few 

 silken threads. The fly (shown enlarged 

 on page 61) comes out of this cocoon 

 in about five days or even less. 



This little caterpillar is a real pest to 

 the rose bushes, as complete defoliation 

 means the loss of many fine autumn 

 blooms. Spraying the plants with soap 

 suds, tobacco juice, or dilute kerosine is a 

 good remedy for killing the caterpillars 

 if one is possessed of a sprayer. Those 

 who have not one will find that the 

 caterpillars can easily be collected from 

 the bushes and killed at the beginning 

 of the July and August attacks, if they 

 are marked down then. Once, however, 

 the caterpillars have been allowed to get 

 to the third generation or fourth, one 

 must not look for any fine blooms from 

 the trees for the rest of that season.
