Do you see very many butterflies?

I realized this week that I do not see as many butterflies as I used to. I do not know if there are really fewer of them, or if I just do not notice, or if I am never outside. Do you see very many butterflies? I had the caterpillars of a black or blue swallowtail on my parsley, but they ate it all and left. I had looked the caterpillar up in a book. I think next year I shall plant more flowers that bloom all summer; maybe I will see butterflies again. Maybe they have all been at your house this summer.
