Bumbles on milkweed - Bombus griseocollis - Male
Pacific (Franklin Co.), Franklin County, Missouri, USA
July 5, 2010
Size: 20-23 mm
I think these are Bombus griseicollis.

Can someone explain why I see so many males in July, when there don't seem to be any gynes of the year around?

I think one always sees more
I think one always sees more males than gynes. We have our milkweed covered with male gris too. I did see maybe three queens, nice and fresh, on other plants, so they're around.
