Family Leucospidae
Explanation of Names
Leucospidae Fabricius 1775
Numbers
6 spp. in a single genus in our area, >130 spp. in 4 genera worldwide(1)
Size
4-17 mm
Identification
Usually black and yellow/red. Wings folded longitudinally at rest. Ovipositor usually long (not so in L. robertsoni & L. texana) and curved forward and upward. Metafemora greatly swollen and toothed ventrally.(2)
Food
parasitoids of aculeate Hymenoptera (mainly solitary bees, less frequently solitary wasps, e.g. Vespidae and Sphecidae)(1)
Life Cycle
Eggs are deposited externally on the host larva or nearby. The first instar larva does not feed at first but searches the host cell for competitors; only one parasitoid larva survives and develops as an ectoparasitoid sucking the body fluids of the host.(1)
