71.5 per cent are deposited elsewhere than on the squares has a very 

 important bearing on the question of poisoning the young larvie, and 

 will be referred to again in the following pages of this bulletin. It is 

 quite possible that the large number of eggs laid upon the squares is 

 accidental and due to the attraction offered by them on account of the 

 nectaries at which the moths feed. At any rate, they appear to ovi- 

 posit indiscriminately wherever they happen to alight on the plant. 



It is by no means unusual for a moth to oviposit occasionally on 

 dried leaves or sticks beneath the plants, or even on the bare surface 

 of the ground itself. It appears that old and worn females do this 

 more often than strong and healthy ones. 



OVIPOSITION ON OTHER PLANTS. 



The remarks on oviposition would not be complete without some 

 reference to the great variety of plants on which the eggs are laid. 

 The following table contains the records of the eggs found on miscel- 

 laneous plants during the seasons of 1908 and 1904:
