Phylogenetic species tree of Hyalophora silk moth species with C. promethea outgroup. This tree represents individuals from previous published trees^12,13, with all hybrid and potentially misidentified individuals removed. Posterior probabilities are indicated at each node, highlighting uncertainty of branching order amongst the rapidly diverging Hyalophora lineages. Blue branches indicate species constructing polymorphic cocoons and red branches indicate species that construct monomorphic, compact cocoons only. Purple branches indicate that the presence or absence of polymorphism is unknown (H. mexicana and H. leonis).
