Lathrolestes ensator (Brauns, 1898)

As a more colourful species, females of L. ensator have a red metasoma (except for its first tergite). Its mesosoma is predominantly black, but there is some yellow on its pronotum, tegulae and frontal orbits. Its ovipositor is long, longer than its metasoma, and it has apical teeth ( RESHCHIKOV, 2015a). The long ovipositor is used to parasitize the rather uncommon ‘Apple sawfly’, Hoplocampa testudinea (Klug, 1816) (Symphyta: Tenthredinidae ).

First report for Belgium; unconfirmed in the Netherlands.
