Biology: Usually secondary parasites of Lepidoptera through Hymenoptera, some primary parasites of Lepidoptera.

Comments: 6 described species. A very distinctive genus in the Nearctic fauna. Propodeal form is very similar to that of Notanisomorphella.

Comparative information:

Notanisomorphella: Clypeal margin not bilobed.

Dasyeulophus: Scutellum and midlobe of mesoscutum with numerous evenly or irregularly distributed setae (but scutellum often with as few as 2 pairs of distinct setae). Propodeum without plicae, and median carina weak.

Sympiesis: Clypeal margin not bilobed. Propodeum very seldom with strong median carina and plicae.
