FOURTEENTH ANNUAL REPORT OP STATE ENTOMOLOGIST 53 



PLIES (DIPTERA) 



The Currant Fruit Fly (Epochra canadensis Loew.). The cur- 

 rant fruit fly continues to do as much damage to currants as in 

 previous years. As yet no entirely satisfactory control measure has 

 been found for this pest. 



Horse Flies {Tabanidae). Horse flies were as abundant as 

 usual, and pestered the picnickers and campers as well as horses 

 in the canyons about the State. 



The March Fly {Bibio albipennis Say). Larvae of a Bibio, 

 probably albipennis, were sent m with requests for information. 

 So far as is known, these insects caused no damage whatever, but 

 their presence in garden soil in great numbers aroused suspicion. 



The Nose Fly (Gastrophilns haernorrhoidalis Linn.). The nose 

 fly, while plentiful, is not recorded as having made any great advance 

 in its spread this season. Some interesting facts regarding the egg 

 and egg-laying habits of this fly were brought out this summer by 

 Dr. R. R. Parker, of the Board of Entomology. These have recently 

 appeared in the Journal of the New York Entomological Society. 



The Onion Maggot (Phorbia ceparum Meade). The onion 

 maggot was abundant this year and completely destroyed several 

 rows of onions on the plots at the Experiment Station. Reports 

 of damage done by this insect were received from various parts of 

 the State. 



Wheat Stem Maggots (Mevomyza americana Fitch and M. 

 ni Ji i n vlris Macq.). There was no report of serious injury by the 

 wlieat stem maggot until the latter part of July. The damage at 

 this time was done to the plant while in blossom. The stalk was 

 cut just above the last node, causing the head to die, while the 

 leaves appeared perfectly healthy. This trouble was general in 

 Montana. 



BEETLES (COLEOPTERA) 



Blister Beetles [Epicanta maexilata Say and E. pennsylvanica 

 D. G.). These two species of blister beetles were reported as being 

 injurious to sugar beets. They are both common in Montana and 

 have been injurious for many years. 



Nuttal's Blister Beetle '{Canlliaris niittalli Say). This blister 

 beetle was reported from the Judith Basin Substation as feeding on
