REPORTS ON INSECTS OF THE YEAR 

 Division No. 3, Toronto District. — A. Cosens 



Only a few insects were noted as particularly plentiful this year. Two leaf 

 rollers were among these. The species, Anacampsis populella Clemens, that 

 feeds upon the foliage of the large-toothed aspen, Populus grandidentata Michx, 

 had infested the trees in High Park to such an extent that some branches had 

 almost every leaf rolled. The larvae of this form appeared to be almost mature 

 on June 22nd. The other leaf-roller, Cacoecia hewittana Busck, was feeding 

 upon second-growth soft elm, TJlmus Americana L. The moths emerged the 

 last week of June. The latter species was kindly identified for me by August 

 Busck, Smithsonian Institution, Washington. He states that the pest is common 

 to both Europe and America. On the same specimens of Ulmus, on which were 

 the leaf -rollers, galls were fairly common. These were on the foliage and con- 

 sisted of a thickening of the leaf blade along the lines of the veins. The infected 

 leaves were also folded with the upper surfaces within. The gall-producer in 

 this instance is a gall gnat, Phytophaga ulmi Beutm. 



On June 30th, the rose chafer, Macrodactylus sub-spinosus, was noted in large 

 numbers feeding upon wild roses and other plants in High Park. About the 

 same date, rose growers in the vicinity of the park stated that the beetles were 

 plentiful upon their cultivated roses. These beetles are easily recognized. The 

 body is slender and thickly clothed with fine, yellow hairs, which give it a yellow 

 colour. The legs are long, slender and pale red. This pest is difficult to combat. 

 A poison spray is not very effective and about the only other plan suggested is 

 to jar the beetles off the bushes into a dish of kerosene, a method that would be 

 applicable only on a small scale. These beetles do considerable injury to plants 

 as not only do the adults feed upon the foliage but the larvae also feed upon the 

 roots. 



Along the beach at Kincardine, during the month of August, that curious 

 Hymenopterous insect, Pelecinus polyturator, was quite numerous. 



This insect, which is glossy black in colour, has short wings with only a few 

 veins. The female can be readily recognized by its long, slender abdomen, nearly 

 five times the length of the head and thorax together. This elongated abdomen
