Poor butterflies :(( and a question for some people

Jonathan and Fellow Lepsters,

In my opinion (and I hear this comment often as well) when lay people say
that butterflies were once super-common, what they are remembering is a time
when the Painted Ladies were invading by the zillions-- something that
happens in Canada once every ten years or so.  I hear the same thing from
people with bird feeders-- one winter they get hordes of winter finches
(during what ornithologists call an irruption), and from then on they assume
that the birds have all died off.  This, in my opinion, has more to do with
human psychology than with population ecology, and I really don't think
these ancedotal accounts are a reliable source of natural history
