Insect Life on the Western Arctic Coast of America 2 IK 



The flowering period, generally speaking, is about one month for each species. 

 A few observations relating to this matter, of such vital importance to the 

 insects, are given: 



1915 



Middle of July. 



Salix anglorum; male catkins dropped. 

 Eriphorum Scheuchzeri; unripe fruits. 



End of July. 



Salix pulchra; male catkins dropped. 

 Eriophorum an gusti folium; unripe fruits. 



Beginning of August. 

 Oxyria digyna; unripe fruits. 



Anemone parviflora (June 28; ia shelter of boulders). 

 Draba nivalis; unripe fruits. 



Middle of August. 



Dryas integri folia; unripe fruits (a few flowers). 

 Saxifraga oppositifolia; unripe fruits 



End of August. 



Androsace septentrionalis; unripe fruits. 

 Juncus spp. ; unripe fruits. 

 Carex spp. ; unripe fruits. 

 Arctostaphylos alpina; unripe fruits. 

 Pedicularis lanata; unripe fruits (a few flowers). 



September 



Though most of the plants have finished their bloom, compositae and grasses 

 are still in flower. If a severe frost comes, as in 1915, about the middle of the 

 month, many of the plants will fail to ripen their seeds, but otherwise it is possible 

 for the flowers of many of the species to finish the cycle. Besides the species 

 given above as having finished their flowering during July and August, seeds of 

 the following were collected during September, 1915. 



Various grasses (Elymus, Alopecurus, Poa, etc.) 



Cochlearia groenlandica 



Erigeron compositus 



Oxytropis nigrescens 



Taraxacum ceratophorum 



Pedicularis spp. 



Artemisia sp. 



Lychnis affinis 



Armeria vulgaris (Statice armeria) 



1916 



The first flowers of Saxifraga oppositifolia were found the last days of May 

 on a south exposed, snow-free slope, and from Salix anglorum the catkins had 

 just emerged. The earliest flowering plants (Saxifraga, Pedicularis, Anemone, 

 Draba, Eriophorum, etc.) also had flower buds now (1916). On June 6, Salix 

 pulchra had the male catkins of the size of a big pea. 



By the middle of June the first flowers, the male catkins, of Salix anglorum 

 were out on Chantry island, and some days later, June 20, those of Salix pulchra. 

 The first flowers of the following species were found : 



June 2X-SS. 



Dryas integrifolia Lesquerella arctica 



Androsace Chamaejasme Draba alptoia, 



Pedicularis lanata Braya purpurascens 



Oxyria digyna Eriopharum Boheuoheeri
