Ibalia leucospoides ensiger (Hymenoptera: Ibaliidae) has been shown to be an effective parasitoid of the invasive European Woodwasp, Sirex noctilio (Hymenoptera: Siricidae). Scanning Electron Microscope (SEM) images were taken of male and female antennae of I. leucospoides to help determine the amount and types of sensilla present. Both sets contained the same sensilla although in differing quantities: sensilla trichodea, sensilla campaniform, sensilla chaetica, sensilla placodea, sensilla coeloconica, and assumed sensilla ampullacea.
