Polydamas Vs Pipevine Vs Eastern Black Swallowtail Eggs

We had a very active Pipevine Swallowtail laying eggs today.  As I was watching this Butterfly lay her eggs, I started to get confused about the differences between Polydamas, Pipevine, and Eastern Black Swallowtails.  Here are some of the differences and similarities.

1. Polydamas Swallowtails don’t have the “tails” like Eastern Black and Pipevine Swallowtails
2. Pipevine eggs are brown, rust colored whereas Polydamas eggs are yellow (see pictures below).  Both lay their eggs on Pipevine
3. Pipevine Swallowtails have one row of orange dots when their wings are closed, whereas Eastern Black Swallowtails have two rows
