Over Easter weekend we went camping at McKinney Falls State Park just outside of Austin. As we were hiking along one of the trails headed back to our campsite we came across several pipevine swallowtail caterpillars walking in the grass and crossing the bike path. We searched and searched for pipevine but didn’t see any but there must have been some nearby. The caterpillars were in dangerous territory so we carried them over to a tree and out of the bike path—hopefully they managed to find more pipevine to chow!
