This is a brisk and lively species, always hiding during the 

 day in sallow bushes, especially the large and woolly leaved 

 sallows, flying out instantly when disturbed, to buzz about a 

 little before again hiding. At sunset flying in numbers 

 over the sallow bushes, resting for a moment on a leaf and 

 then dancing aloft and around, and continuing this amuse-

 Orkneys. In Ireland recorded from Kerry, Sligo, Ennis- 

 killen, and Antrim. Abroad it is found throughout Central 

 Europe, Italy, Finland, and Scandinavia.
