Randy, nationally, the corn acreage (and associated clothiandin usage)
is highly concentrated in northern Iowa, southern Minnesota
and northern Illinois:

My understanding is the corn grown in that area sheds pollen
only for a 7-10 day period in July. I am not aware that a "pollen
dearth" exists in that region in July that might tend to cause the
bees to gather corn pollen. Does anyone even have a video
of bees in a corn belt State gathering corn pollen? I searched
YouYube and couldn't find any.
Bottom line is I am wondering just how bees in the corn belt
could be significantly exposed to clothiandin contaminated corn
pollen on a landscape scale and over a multi-week period?
