The euphorine braconid Leiophron plagiognathi is a parasite of Plagiognathus sp. (Heteroptera: Miridae), which breeds on Spirea latifolia L. The species and its final instar larva are described from Belleville, Ontario, Canada. Brief observations on the life history of both species show that L. plagiognathi overwinters in the cocoon in soil and strikes early instar nymphs of Plagiognathus in June. The larva develops chiefly in the adult, and in 1962 and 1963 emerged in July. L. plagiognathi has one generation per annum.
