Host-acceptance behavior of Telenomus reynoldsi Gordh & Coker attacking eggs of a bigeyed bug, Geocoris punctipes (Say), was observed to consist of host examination by the antennal clavae, mounting, probing, drilling, and oviposition, usually followed by host marking and occasionally by reexamination. Females exhibited preoviposition host guarding and also wing and antenna flipping during oviposition in response to intruding females. Total handling time averaged 4.5 min. A proteinaceous substance, possibly originating in the host's ovaries, that adheres the egg to the substrate is a key host-recognition factor.
