Common and generally distributed. 

 Continental distribution : Sweden, Germany, Hol- 

 land, France. 



Obs. I have always taken this species on birch and generally 

 where no Ribes was near. Nevertheless it has been stated by Bechstein 

 to feed on Ribes rubrnm, the larva being further stated to be twenty- 

 footed, to have a green body covered with black tubercles and a black 

 head, and they are said to feed in companies in May and at the com- 

 mencement of June, appearing in the perfect state at the end of July 

 (cf. Kalt., I.e.). Kaltenbach, who quotes these observations, says that 

 he himself always captures the insect on low-growing willows.
