Distribution

Widely distributed throughout the Holarctic Region; also known from Africa, Middle East, Orient and into Southeast Asia, Australia.


Hosts

This is a highly polyphagous species, which attacks mainly agromyzids but will more rarely attack other hosts. Noyes (2002; 2003) lists almost 40 different agromyzid hosts, as well as a Tephritidae, and Lepidoptera in the families Gracillariidae, Lyonetiidae, and Nepticulidae.

Comments

D. isaea is a common parasitoid of agromyzids which has been used in biological control programs in Europe (see Noyes, 2002, 2003 for references).
