Ennominae

Ennominae is the largest subfamily of the geometer moth family (Geometridae), with some 9,700 described species in 1,100 genera.

Most species are fairly small, though some (such as the peppered moth) grow to be considerably large.

[citation needed] For example, the Boarmiini are sometimes massively expanded to include the Bistonini, Bupalini, Erannini, Gnophini, Melanolophini, Phaseliini and Theriini.

The Alsophilinae, usually treated as a small subfamily in their own right, might simply be a specialized lineage of Boarmiini.

Described under Eogeometer vadens, it measured about 5 mm (0.20 in), and was estimated to be 44 million years old, dating back to Eocene epoch.
