Canadian Arctic Expedition, 1913-18 



Apart from the forest insects, the insect life along the west side of Coro- 

 nation gulf and the lower Coppermine is probably very similar to that atBernard 

 harbour, though the mosquitoes, etc., become more troublesome farther south. 



SOUTH SIDE OF CORONATION GULF (INCLUDING BATHURST INLET, NORTH 

 OF LATITUTE 67| DEGREES NORTH) 



Owing to the milder climate, vegetation and insect life between Coppermine 

 river and Bathurst inlet are at least a week earlier than at Bernard harbour 

 and cessation of plant life is, probably, later (PI. II, fig. 2). Very few insects 

 were secured by previous expeditions. Hanbury collected butterflies, the 

 earliest ones, apparently at cape Barrow, June 26, while flies, spiders, etc., 

 were noticed on June 10 (Kent peninsula), and the first mosquitoes at Lewes 

 islands on June 27} Insects captured by the Canadian Arctic Expedition were 

 mostly picked up casually, but from them and from the narratives of Hanbury 

 it may be assumed that the insect life is practically the same as at Bernard 

 harbour. The paucity of vegetation on many of the rocky islands causes a 

 scarcity of insect life (PL X, fig. 1). 



Below is a list of insects secured by Hanbury and by members of the 

 southern party of the Canadian Arctic Expedition; the latter ones are from 

 Tree river and Gray bay, in July, and from cape Barrow (PI. X, fig. 2), and 

 Bathurst inlet in August and September.

The saw-flies were reared from larvae collected in galls on leaves of Salix 

 reticulata at cape Barrow, August 14, 1915. They pupated the following June, 

 and the adults emerged a few days later (Rearing 90) . 



". In summer the mosquitoes seem to be much more numerous and trouble- 

 some along the south side of Coronation gulf than they are along Dolphin and 

 Union strait, probably because the land near the coast is less barren, and more 

 sheltered from summer winds off the ice. In the vicinity of Hood river and 

 the neighbouring parts of Arctic sound and Bathurst inlet the black flies (Simu- 

 lidm) were numerous enough to be troublesome in late August and early 

 September, a rare thing on other parts of the Arctic coast with which I am 

 familiar." (R. M. Anderson.)
