Paul Cherubini caught out yet again

[Mike Leski]

I observed that adult monarchs were abundant in the UP of Michigan over Memorial Day weekend and outnumbered all other butterflies combined.  All were "fresh".  Near Peoria, IL this past weekend, modest numbers were observed, all "aged" individuals.

The simple reason it hasn't been publicised is because it isn't true.
That isn't Dr Oberhauser's original graph!


I don't propose to go over Paul Cherubini's history here but suffice it
to say this is not the first time! I don't know any sensible scientist
who takes any notice of what he says any more. Interested newcomers
should do a few searches on his name, or read the book "Four wings and a
Prayer" by Sue Halpern.


Paul Cherubini doesn't give a source for the graph but it would appear
to come from the newsletter of the Monarch Larva Monitoring Project
which is run by Dr Oberhauser and her colleagues.

http://www.mlmp.org/pdfs/mlmp2006newsletter.pdf

You'll find the graph at the top right hand corner of the second page.

For those who have difficulty comparing the graphs I have compiled a
web page which puts the two together when the changes in Paul
Cherubini's graph become very obvious.

Paul Cherubini's graph appears to have been altered to say something
which enables him to make a conclusion that is more sympathetic to the
pesticide companies whose products he sells.
