Point are from the northwest, usually rather cool bree;^es. 

 Preceding a storm by a day or so the wind would shift to the 

 south with a rise in temperature; it would then suddenly shift 

 back again to the northwest with the accompanying storm. 

 It was just after such storms that insects of all sorts were 

 found on the beach, and as they w^ere usually alive though 

 badly battered when just washed up it would seem that all 

 came from the Point or the near vicinity. Many insects 

 would fly out or would be blown out over the water with the 

 warm south wind and would naturally be beaten down with 

 the north wind and the storm. They were then washed on 

 shore, probably with the aid of currents. The shore birds 

 had a great feast at this time, and the collector had to act 

 quickly if he would get ahead of them. 



Two live specimens of Thecla edzvardsil and the upper 

 w-ings and head of Catopsilia euhule were found in the wash 

 up. Neither were taken elsewhere, and this is apparently the 

 only record for Catopsilia eiihulc for Michigan. 



Lozvcr Beach : A few butterflies were attracted to the damp 

 sand or by decayed fish, insects, etc. Grapta j-album and 

 Limenitis arthemis were noticed in particular. 



Wide Upper Beach: This part of the beach is dry through- 

 out the summer and is only touched by the lake during some 

 of the severe fall storms. The vegetation consists of coarse 

 dune grass, beach pea and occasional clumps of scrubby wil- 

 low. This seems to be the habitat for a few grass moths 

 and occasionally a butterfly was seen. The upper limits of the 

 upper beach are rather indefinite but would include such sand 

 dunes as have similar vegetation. Near the mouth of the 

 outlet to Cranberry Lake close to the Post Office is such a low 

 sand dune area, and, in addition to beach grass, etc., a kind of 

 spiraea grows in clumps and attracts numbers of butterflies.
