Oviposition behaviour (attack upon the host spider) of Zatypota albicoxa was elucidated by Takasuka et al. (2009 Entomol. Sci. 12 232-237). The female wasp perches on the mid height of the irregular 3D web constructed by Parasteatoda tepidariorum or hangs from a vertical thread for capturing a prey (ambush style) or climbs non-sticky frame thread to approach directly (climbing style).
To induce the female to attack spiders artificially, I utilized females of Z. albicoxa that employ the ambush style of attack because most females usually hung at the mid height of the web motionlessly. The female wasp was introduced into an aquarium with the web already constructed but without the spider. After she assumed the ambush position (perched on the web), a spider clinging on a wooden stick was introduced to her. As soon as the spider reached to the web right beside her from the stick, she grasped and stung it.
