Forum: Survey of Evaniid Wasps (Hymenoptera: Evaniidae) and their Cockroach Hosts (Blattodea) in a Natural Florida Habitat

Mark Deyrup, Thomas H. Atkinson


Over a 3-year period 1,359 evaniids, representing four species, were collected in a mature sand pine habitat at the Archbold Biological Station in south-central Florida. All species fly for at least six months of the year and show annual fluctuations in abundance. Seventeen species of cockroaches occur at the ABS; the most probable hosts for evaniids are members of the genera Parcoblatta, Ischnoptera, and Cariblatta.
