Eanye. World-wide. 



The species of this very distinct genus are known to prey upon 

 various small Tortricid and Grelechiid moths, and I once bre.I 

 numbers in a room of stored apples, where they emerged, in all 

 probability from the codlin moth (cf. Zoologist, 1909, p. 213) 

 though not elsewhere recorded as a parasite of this species.
