Japanese Knapweed is about 30% in bloom so since this plant is a major attr=
actant for insects includiing butterflies=2C I checked out a site on the So=
uth Mountain (Kings) that has been productive in the past. There were sever=
al good stands of Knapweed & about 10 fritillaries were there=2C seemingly =
basking rather than nectaring. Sweat bees (three sizes-different families) =
were numerous=2C Honey Bees (far from any crop field) were also plentiful &=
 there were a few bumble bees. There was not a single fly!!. There were a f=
ew other butterflies.
Last summer Knapweed was largely ignored by all insects & I'm not sure what=
 their cycle would be. I fail to understand why this plant & many other wil=
d plants do not produce pollen or nectar each year. Seems counter-productiv=
e.
