Vanessa cardui – Painted Lady

Caterpillar foods:  thistles, Burdock and hollyhocks; occasionally nettle, alfalfa, soybean, beet, borage, plantain  (Bugguide)

The most widely distributed butterfly in the world.  (BAMONA)

This species can’t survive our cold winters.  It migrates up every year from warmer places.  Some years there are big ‘invasions’ – usually at least several years apart.  (Bugguide)

7/30/2017  This was another big migration year.  I watched a female lay an egg on this Canada Thistle.
