Butterflies on Hemp agrimony

The rides of the local forest are wall to wall Hemp agrimony, Eupatorium cannabinum, which, at this time of year, is a major nectar source for many butterflies. I snapped these over a couple of hours in two afternoon sessions.

Hemp agrimony as far as the eye can see.

 

 

Of course other insects like it too....

Volucella inanis --- I think

.....and others have different preferences.
