Something wrong with my wasps

[flowerbug]

we have usually a pretty good diversity in wasps/hornets/bees, but i've seen a decline in the larger bumblebees the past few years. i'm planting squash, cucumbers and more late summer flowers to try to help them out. beans i always plant no matter what, the smaller bees seem to like the lima bean flowers.

if you get a chance look into putting up some bee hotels.

The wasp like the pollen of the bean at the familie vigna theirent foraging the flowers! I grow the variety dall'occhio.
