Hi Al. My observations over 5 decades of active field time looking for
butterflies has given me the same conclusion as yours:
Butterflies in general are less abundant. Regarding the antiopa, I mostly
see them in very small numbers. Off the cuff, I can remember
only 3 years when I have seen them abundant. Somewhat similar to the
American False Comma aka Compton Tortoiseshell which has
occasional population blooms following by years of low numbers, in my
experience. Perhaps others have different experiences to share.
