" In multitudes during the day among hedges on the sea-coast ; 

 in the evening, in columns about the tops of trees, appearing like 

 smoke at the distance of a furlong. It is attached particularly to 

 water-cuts in the neighbourhood of the sea. The reddish gnat 

 (C. ciliaris, L.) is more general, and enters more into houses, but 

 I have not observed it in such clouds as C. detritus. 3 ' Hal. MSS.
