More butterflies on the way!

I planted some fennel in my garden, so that I would have a place for the black and yellow swallowtail butterflies to lay their eggs, I have watched all summer, and finally tonight I found 10 tiny caterpillars on my fennel plant. There have already been a number of swallow tails in my flowers, so now I am excited to see that there will be more..Yes, it doesn't take much to excite me...I live a simple life.
