Peak Vs. Preview Migration Pattern?

[Diane Falk]

Here in (Lake County), Northeastern, Illinois at Serendipity children's
Memorial Gardens my Monarch tagging opportunities have slowed as the
low (40's F) night temperatures and heavy morning dew increase.  I
recall in 1999 we endured high temperatures and drought---decreased
nectar resources, as well as a migration peak in _October_.

Question:  Has everyone given up on the late September---early October
migration phenomenon?  I observed Monarch flight _spirals_ as late as
last week!  The steady and _pathetic_ low numbers of migrants behaved
too _unlike_ the Monarch migrators from Wisconsin,...and probably Canada
(Great Lakes Region) which I observed last year, and in the past.

Catch 22:  I observed Night Hawk migration as well as Odonata just last
week.  Many dragonflies remain behind.  Canadian winds seem once again
to have triggerred migration  behavior. Now with return of warmth I look
forward to more migrants and late emergence.

Time will tell.  Sincerely, Diane Falk
