This is where Frank counts the monarchs overhead as they migrate south to Mexico in September. The location is at the main pavilion near the beach (far left in picture). You are looking NW where the monarchs come into view overhead. Lake Huron would be behind you. Frank stands at the brown sign that is far right in the picture.

Autumn Migration Harrisville, 2021
Eleven monarchs observed on directional flight on July 26th, 2021. This is very early since the old record was one on August 11th, 2015. I started record keeping in 2010. The average directional flight is August 15th.

The monarchs came in four small waves migrating south down the Lake Huron beach at Harrisville State Park on September 24-27. A total of 244 were counted (169, 54,14, 7). This is low for a migration, but not bad after 2 1/2 days of rain and drizzle with the temperatures in the 50's. Although the weather has been 100% sunshine with the temperatures in the low 60's, no monarchs have been counted on the 28th to the 30th. The low temperature at night has been 47, 41, and 36 degrees F. The first monarchs were seen entering Mexico on September 29th, 2021. They have another 300 miles to go to arrive at the sanctuaries. Will more monarchs be counted around Harrisville in October and November?

Monarch Butterfly Presentation and Tagging August 28th, 2021
This event was cancelled again. However, there were thunderstorms about, so I decided to watch monarchs migrating through my flower garden, not far from the park, and observed 4 monarchs on my Joe-pye-weed plants from 5 to 6 PM before a thunderstorm roared through. I will not be presenting and tagging at the park beginning in 2022, because I will not be raising or tagging monarchs. However, I will be counting monarchs on a NW or WNW winds on the beach at the main pavilion during the month of September from 10 AM to 3 PM.

Monarch Presentation at Harrisville State Park, Saturday, August 31st, 2013

THERE WAS A VERY BAD DROUGHT YEAR IN 2013. THE VERNAL POOLS WERE ALL DRIED UP ALONG THE LAKESHORE. I COULD NOT RAISE OR CAPTURE MONARCHS. SO, FOR THE PRESENTATION, I SPOKE ABOUT THE MONARCH MIGRATION AND SHOWED SOME OTHER SPECIES OF BUTTERFLIES SHOWN BELOW THAT I HAD NETTED EARLIER IN THE DAY.
