INSECTS OF LABRADOR 



The Insects, excluding the Beetles 

 BY CHARLES W. JOHNSON 



OUR knowledge of the insects of Labrador is based largely on 

 the various papers by Alpheus S. Packard. The lists of the species 

 recorded in these papers were later brought together and pub- 

 lished in his work, The Labrador Coast. In this work about two 

 hundred and twenty species are mentioned. A few additional 

 species from the interior are listed in A. P. Low's Report on Ex- 

 plorations in the Labrador Peninsula. 1 These, with a few scattered 

 species, make the total number about two hundred and fifty. 

 This is a small number if we consider the whole Labrador penin- 

 sula, but a large number when we take into account the limited 

 amount of entomological work which has been done and the small 

 area covered. 



A. P. Low defines the southern boundary of the Labrador pen- 

 insula as a straight line extending nearly east from the south end 

 of James Bay, near lat. 51, to the Gulf of St. Lawrence near 

 Seven Islands, in lat. 50. This gives a clearly defined geograph- 

 ical area, which, bordered by Arctic seas, and a more elevated 

 interior, gives quite uniform climatic conditions, and would make 

 it possible to study the insect fauna to better advantage than if 

 it were limited by political boundaries. 



The section from which nearly all the insects have been collected 

 (the immediate coast-line) is in that portion of the boreal region 

 which has been designated as Arctic, the flora and fauna of which 

 are largely governed by the effect of the winds from the cold Arctic 

 seas. On the other hand, a short distance inland, we enter the 

 subarctic forest belt, or Hudsonian Zone, with a much richer 

 insect fauna than could exist on the bleak, storm-swept coast,
