The popular belief that the round-headed apple-tree borer, Saperda 
Candida, and the codling moth, Cydia pomonella, are common feeders 
on Crataegus has not been borne out by the writer’s observations. In 
a number of natural thickets where hawthorns and seedling apple grow 
together the round-headed borers have been watched for two years. 
The adults were quite commonly found resting on the foliage of both 
hawthorn and apple in June and July but the larvae could be found only 
in the apple. The apple was so heavily infested that very few trunks 
remained standing and many young sprouts from the roots had grown 
up in their places. The larvae were found girdling these sprouts and 
were also infesting a well kept orchard across the railroad track. The 
hawthorns showed no sign of having been touched by the borers. 
At least two of our common species of hawthorns, Crataegus punctata 
and C. pruinosa were present in these thickets. 
The codling moth has not been found among the insects reared from 
the haws during the past two seasons and only one record has been 
found of its ever being reared from hawthorn. That is in the notes of 
the late Professor Slingerland. He states that in September 1890 
“I gathered a lot of haws and placed them in cages to breed the cod¬ 
ling moth. Examined several (25 perhaps) of the haws and never 
failed to find at least one larva in each. May 13 one adult emerged. 
Several other smaller moths were found in the cages also. May 19 
one adult emerged and is pinned.” The smaller moths were probably 
the lesser apple worm, Laspeyresia prunivora, since this species has 
been reared in abundance from the haws. The larvae of L. prunivora 
have undoubtedly been mistaken for those of the codling moth in
