The Swarming of a Ply, Limnophora humilis Zett., in 

 Spring. — For a good many years we have had in autumn large 

 numbers of this little fly swarming on the windows and ceilings of 

 the bedrooms at Lahill, Fife, but until this year have never seen 

 them in spring, when on 3rd April 1922 many were found crawling 

 sleepily on a window with an eastern exposure. Knowing that they 

 were not common at this season, we caught some and took them to 

 Mr P. H. Grimshaw who confirmed our identification of the species. 

 He kindly sends us the following information : " In the Efit. 

 Mo. Mag. (October 192 1, p. 240), J. E. Collins says, 'This species 

 is not at all uncommon and is one which hibernates in houses ; 

 numerous females with a few males may often be found on windows 

 in the late autumn. In the open the species is more usually found 

 during August. . . . Dr Eltringham bred this fly from horse-manure
