It sometimes appears in larger numbers and almosfc covers 

 the host plant, for inst. Bh. lycopocUoides at KjoUefjord. It 

 prefers open coast and does not enter far into the great 

 fjords, and is, in general, smaller than farther south. I have 

 tåken it bearing reproductive organs in the later half of June, 

 in July, and in the first part of August. 



Distribution: Pretty common along the open part of the 

 coast and at some places abundant.
