A Lesser Maple Spanworm Moth in Warwick, RI.
Nectaring on Platanthera dilatata
The Macariini are a tribe of geometer moths in the Ennominae subfamily. Though they share many traits with the Sterrhinae, this is probably plesiomorphic rather than indicative of a close relationship, and DNA sequence data points to the Boarmiini as particularly close relatives of the Macariini. All things considered, this tribe might still resemble the very first Ennominae more than any other living lineage in the subfamily.
