Number: 1000

multiple clusters sighted in willow tree, windy, wet recently
lots of nectar sources, home garden to include sunflowers, milkweeds
my first sighting, too many to count!!

Editor's note: contacted observer for more details on this sighting

my spouse spotted butterfly activity mid day, no method to count, windy day, butterflies appeared to be seeking shelter in large willow tree allowing them to roost together in clumps, come and go as they pleased

overnight temps cool 50s, very wet especially for here north of Pierre on the bluffs overlooking the Missouri River

farm country, miles of GMO crops, continual roundup applications per aerial drops

I began creating habitat for butterflies for a couple years, purchasing both northern hardy milkweed seeds and harvesting local milkweed from ditches, lots of late blooming nectar sources on our grounds 2.5 acres

hope this helps the cause, I had no idea of the concept of roosting, amazing to witness. web site is amazing
