First tiger swallowtail caterpillars of 2013!

It's late August, but we finally found some tiger swallowtail caterpillars on our tulip tree! First we noticed one on a leaf, then another, and then a bigger cat near the top of the tree.

What a surprise to find this several-day-old tiger swallowtail cat on a leaf near the top of our tulip tree!

We placed all three tiger swallowtail cats in this container. Two branches of the tulip tree have been inserted into sand to keep the foliage fresh.

This is our tulip tree, which we found as a foot-high sapling in our neighbor's garden four years ago.

We included this photo taken on June 5, 2011, to show you what the flower of mature tulip trees looks like. I saw this flower on a large tulip tree while I was on a run in the neighborhood in 2011. Our tree has yet to flower.

We included this photo of the female tiger swallowtail to show you what this butterfly looks like. If the three cats above grow and develop into chrysalises, the chrysalises will overwinter on our unheated back porch and butterflies will emerge in May 2014!
