Unlike last year, when I saw a grand total of 2 Monarch butterflies, I am seeing a lot of Monarch butterflies this year. They especially love Buddleia 'Potter's Purple'. On Wednesday I saw as many as 15 the two butterflies bushes in the big bed. They must have fueled up and moved on, as I didn't see many again until today.
Why were there so few last year and seemingly normal numbers this year I wonder?
