It is an animation of Zatypota albicoxa (Ichneumonidae) which is a parasitoid of Parasteatoda (=Achaearanea) tepidariorum (Theridiidae), conducting oviposition behavior under the artificial condition.
This wasp has two modes of oviposition behavior that the one the wasp perches on one of the underslung threads of an irregular three dimensional web and imitates a prey to facilitate approach of the host spider (ambush style), and the other the wasp climbs the thread with its own legs and attacks the host spider (climbing style).
At the time, two host spiders were accidentally present on the same web, but were unaware of the wasp. Then they began to struggle with each other. Although the wasp had shown the ambush style, the spiders didn't gain access to the wasp. So the wasp flew toward one of the spiders from short distance away while they grappled.
The wasp seems to be able to change its behavior according to the situation like this.
