Martha,  Don't you think it is safe to say that a great many people outside
the Corn Belt do not know about de-tasseling.   The only reason I know
about it is because I grew up in Iowa and my grandparents had a very large
farm.  Bt is an "issue" and gets the attention.  But as you pointed out,
the mowing and herbicide spraying in the ditches would seem to be a much
much more relative issue to Monarchs.  When I was a kid virtually all the
rural roads more miles around my grandparents farms were gravel. Today they
are mostly black-top.  Back then (50's) the ditches were largely weedy and
supported large and diverse butterfly populations.
