On Thursday May 25th, Monarch adults abruptly appeared
in large numbers in the Copper Harbor area of
Michigan, near the northern tip of the
Keweenaw Peninsula.

This is the northernmost tip of
Michigan other than Isyle Royale and is an area where
Monarchs congregate. Along Brockway Mountain
Drive, which runs along the highest elevated ridge in
the area, at least 1-2 monarchs were in view at a time
for the entire 10+ mi route along the ridge.

This was
my third day sampling for bog butterflies across
Michigan's Upper Peninsula and the first day I saw any
Monarchs.

It is not unusual to encounter the first
Monarchs there at this time, but it is
unusual for them to appear abruptly in large numbers.
Strong storms had moved through the area the previous
night, so their abrupt appearance
in numbers may well have been fallout from the storm.
