INSECT NOTES. 27 



the middle of June to middle of July or a little later, lay eggs, 

 which hatch in about two weeks. The young, which are leaf 

 miners, soon make cases, which they later attach to the bark, 

 thus passing the winter, beginning to feed again early the fol- 

 lowing spring. If the trees are sprayed for the codling moth 

 the case bearers are also destroyed. (Lot 762.) 



Hnarmonia prunivora (Lesser apple worm). 



As we have no Station records of the occurrence of this 

 insect in Maine, it may be of interest to note that a number of 

 specimens of this species was reared August 5-9 from a lot of 

 small apples obtained June 30 from an orchard at Oxford, 

 Maine. The owner of the place reported very serious injury 

 to his crop due to this insect as well as to the codling moth 

 (Carpocapsa pomonella) and the plum curculio. 



According to Fletcher and others this insect also attacks 

 haws, crabapple, plums, and elm and oak galls. The larva feeds 

 upon the apple in a manner similar to that of the codling moth, 

 for which it is doubtless frequently mistaken. Besides by its 

 smaller size the larva may be distinguished from that of the 

 codling moth by the presence of the anal fork. The adult moth 

 expands about ^ of an inch across the wing. The ground color 

 of the front wings is black, with patches of pale rusty red, of 

 gray, and of yellowish white and steel blue oblique lines. The 

 hind wings are dusky gray at the base, shading to black at the 

 apex. 



The insect may be combatted by methods used against the 

 codling moth. (Lot 785.) 



Garden Caterpillars. 



The woolly bear caterpillars, Estigmene acreae,'^ and Dia- 

 crisia (Spilosoma) virginica^ have caused much damage to 

 garden crops, taking practically anything from peas to onions, 

 and to flower gardens. Though very troublesome, neither of 

 these hairy caterpillars were as numerous as during 1908.
