A few Observations on the Tendency of Insects to 

 Collect on Ridges and Mountain Snowfields. 



By Edwin C Van Dyke, Berkeley, California. 



The article on the insect life of high altitudes,* recently 

 contributed to this journal by Dr. L. O. Howard, has tempted 

 me to add a few more notes on the same subject from my 

 own field experiences. 



While collecting in the high Cascades and Sierra Nevadas, 

 I have found at times, particularly during the early summer 

 when insect life was most abundant, that my most profitable 

 work could be done above the normal line of vegetation. On 

 the snow fields insects were to be found either running over 

 those portions adjacent to the bare rocks and ground or more 

 or less widely scattered over the face of the ice at higher 

 levels. On the bare peaks and rocky ridges other insects were 

 also to be found.
