EventMonarch PEAK Migration
Date of Sighting09/08/01
CommentsWow, I've finally SEEN the numbers these guys can form during migration!! This afternoon (9/8/01) in Vining, IA, 42 degrees N latitude thousands of Monarchs were observed roosting in Catalpa, Mulberry and assorted evergreens at the old St. Mary's Church here on the north edge of town. Impossible to count them-they made the trees look like they were full of brown leaves while roosting in clumps! Most of the butterflies were nice and large and all appeared to be very fresh.

Very little nectaring noted at between 2:30 and 3:30 p.m.--primarily roosting and flying around despite the proximity of flower beds which included much goldenrod in full bloom. About 2 miles due East, at the old St. Mary's cemetary, several hundred Monarchs were observed roosting in a row of old evergreens all along the eastern edge of the cemetary.
We had a major weather event locally last night about 9:30 to 10:30 p.m. including over an inch of rain in an hour, major winds (causing serious damage just east of our town) and impressive thunder and lightning. The morning was very cool, damp and overcast until about 1 p.m. here and then in a sunnier afternoon, the temps got up into the lower 70's F.
Unseasonably cold weather here plus mostly overcast skies seemed to have stalled the Monarch gathering here by the 9th. We went over to check in the morning and later in the afternoon (9/9/01) and the trees around the flower beds there (quite a sheltered location) were still "coated" with roosting Monarchs. In the afternoon, temps got up to perhaps 63F and there were some flying all about, but no nectaring was noted either time.
Kind of good luck for the town here as word is spreading around and many folks are taking the opportunity to go and see this marvelous sight!
