Black Swallowtail caterpillar early instar - Papilio polyxenes Grand Rapids, Kent County, Michigan, USA July 20, 2011
I planted Fennel this year to specifically host Black Swallowtails. I've yet to see a Black Swallowtail in my garden,
but found 5 early instar caterpillars this morning! Hopefully they can escape the predators...
