Time for the Tortoiseshells

Every year, around this time, I start seeing Milbert's Tortoiseshells. The Milbert's Tortoiseshell is a medium-sized butterfly, which has wings bordered by a vibrant orange color. Since these butterflies are such a late-season species, they will nectar on anything that is still flowering. Asters are a common nectar source for these guys.

These beautiful insects can be hard to find, so coming across this species is always exciting. One of the best places to find this butterfly is at the Lehigh Gap Nature Center. The trails and gardens at the LGNC attract dozens of Milbert's Tortoiseshells every year. The native Aromatic Aster in the habitat gardens is a popular plant for many late-season butterflies especially this species.
