Numbers
31 genera in the New World
(1), >1,150 spp. in ~50 genera total
Identification
In some,
M1 petiolate;
no forewing 2cu-a (1st subdiscal cell open)
vein reduction: in all genera but two (Aridelus, Chrysopophthorus), the 2nd submarginal cell missing
Food
hosts: adult insects of many orders and families, e.g.:
Periletus, Dinocampus, Microctonus, Centistes spp. attack beetles;
Syntretus attack Hymenoptera;
Chrysopopthorus attack Neuroptera;
Peristenus, Leiophron, Aridelus, Wesmaelia, Holdawayella & Euphoriella attack nymphal and adult Heteroptera and Psocoptera
(1)Life Cycle
Solitary or, in a few, gregarious, koinobiont endoparasitoids of adult insects
(1)Remarks
The euphorine habit of attacking adult hosts is unusual. Several species of Peristenus and Leiophron are used to control Lygus bugs (Loan & Shaw 1987) and other mirid pests (Loan 1980).
Dinocampus coccinellae attacks ladybird beetles and sometimes considered a pest, although not it's not abundant enough to affect coccinellid populations.
