Eutrapela clemataria
(Smith, 1797)
Curved-toothed Geometer Moth, Curve-toothed Geometer Moth, Purplish-brown Looper
Eutrapela clemataria is a multivoltine geometrid native to North America. It is the sole in the Eutrapela. The species is notable as a for the thelyotokous Ooencyrtus ennomophagus, and its eggs have been used in mass rearing programs for . Cooling eggs to −10°C has been demonstrated to maintain their suitability for parasitoid production even after embryonation begins.

Parasitoid Rearing Significance
Research has demonstrated that cooling E. clemataria to −10°C alters them in ways that forestall the typical decline in production that occurs with egg age. This allows mass rearing of Ooencyrtus ennomophagus even after embryonation has begun, which is normally a limiting factor for production.
