The often feed during the night, but take meals in the daytime as well. 

 In fact, they are enormous eaters, though they make but a poor show for 

 it all, and hardly look as if they had any stomach to put food into. 



All of them die off about the end of October, so that one generation 

 never sees anything of its successors, and the males begin to go first. I 

 have seen females late in the fall, when egg-laying was over, with the 

 abdomen split open like a dried up seed-pod. Thus their preparation for 

 death, their appearance in life, and the eggs from which they are 

 produced, all bear "some odd resemblance to the vegetable kingdom. 



They are not generally very plentiful in Ontario ; about a dozen are 

 as many as one can usually find in an afternoon's search around Toronto, 

 and sometimes that number is not seen during a whole summer. 



In 1904 they were unusually numerous, and at Niagara Glen they 

 became quite a plague. I was at the Glen on Sept. 23rd, and could have 

 taken them in hundreds. At the north end, where they were most 

 plentiful, many of the bushes were quite stript of foliage, and even some 

 large trees had been altogether denuded of their leaves. On one lofty 

 tree, whose top still retained a little foliage, a mass of them, almost 

 covering one side of the trunk, reached from the ground as far up as the 

 eye could see. Some constantly ran across the paths, so that it was 

 difficult to avoid treading upon them, and a continual dropping could be 

 heard as they, or their eggs, fell from trees and bushes. They were nearly 

 as numerous in 1906, and again did a great deal of damage to the trees 

 and shrubs. 



A female that I kept at Montreal from Sept. 3, 1894, to Oct. 8, when 

 she died, laid in that short time 112 eggs. 



Some eggs that I obtained in 1904 came to nothing in the following 

 summer, though I watched them till the middle of August. I then put 

 them away in a box, and only on looking at them again, about a year 

 after, did I discover that they had hatched the second year, for the box 

 was full of the remains of infant Stick Insects, that had, of course, all 

 perished for lack of food. I had quite forgetten the occasional occurrence 

 of this delay in hatching, but it was vividly impressed upon my mind by 

 the untimely end of these poor little creatures. 



The illustration, I think, hardly needs further explanation ; the 

 specimens were all taken at Niagara Glen. Unfortunately, the photograph 

 makes the pale green female look darker than the brown ones, instead of 

 lighter, as in the actual specimens.
