Explanation of Names
Dryinidae Haliday 1833
17 subfamilies, >50 genera, and ~2000 spp. worldwide
Females usually have chelate protarsus to hold the host during oviposition.(1) Females of most spp. are wingless; some mimic ants. Antennae 10-segmented.
Male wing
Only the female has front legs with oversized tarsal claws, used to grab leafhoppers.(2)
worldwide and throughout NA
parasitoids and predators of Auchenorrhyncha (most commonly Cicadellidae, Delphacidae, Flatidae)(1)
Life Cycle
Larva develops inside the host, then extrudes in a characteristic sac bulging out of the host's abdomen. Pupation on host plant or in the soil.(1)
Once the female captures a leafhopper, she inserts her ovipositor into its abdomen. As the larva grows, it moves to a chamber that it forms from its molted skins. This chamber protrudes from the side of the host. This protects it from the immune response of the leafhopper.(2)
