M. Deyrup et Th. Atkinson, SURVEY OF EVANIID WASPS (HYMENOPTERA, EVANIIDAE) AND THEIR COCKROACH HOSTS (BLATTODEA) IN A NATURAL FLORIDA HABITAT, The Florida entomologist, 76(4), 1993, pp. 589-593
Over a 3-year period 1,359 evaniids, representing four species, were c
ollected in a mature sand pine habitat at the Archbold Biological Stat
ion in south-central Florida. All species fly for at least six months
of the year and show annual fluctuations in abundance. Seventeen speci
es of cockroaches occur at the ABS; the most probable hosts for evanii
ds are members of the genera Parcoblatta, Ischnoptera, and Cariblatta.
