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 although the wasp had shown the ambush style, the spider was unaware of the wasp and soon turned from the wasp. The wasp had waited to be attacked by the spider but it didn't gain access to the wasp. So the wasp flew toward the spiders from short distance away when it turned away.
The wasp seems to be able to change its behavior according to the situation like this.
