> Why?  Any reports on what is causing the die-outs?

Just a personal observation of my property and the surrounding 20 or so
miles.  Last year was very wet  (65+ inches) and the prior two years (when
they number of colonies increased rapidly) were droughty.  Our 2009-10
winter minimum temp was not very low; frost was max 2-3 inches deep, not
deep enough to effect the colonies in the more well drained fields..
It reminds me of the population dynamics when the gypsy moths and Asian
lady bugs were peaking in the New England region, perhaps  15-30 years ago.
I suspect our extra ordinary populations of dragonflies this year will
prove to be a similar phenom. We have also had an increase in butterfly
populations  on the farm over the last 6 years, IPM?  GM row crops? No more
