Polysphinctine wasps (ichneumonid spider-ectoparasitoids) kill their host spiders in the final phase of parasitism drying the spiders off and weave a cocoon on the web. Legless larvae bear tubercles with numerous minute hooked-setae on their dorsal sides of each segment in order to hang themselves from the web.
This video is 21.5h sequence from killing the host spider (Cyclosa argenteoalba, Araneidae) to cocooning by a larva of Reclinervellus nielseni with the length speeded up x640. Sucked spider's haemolymph is clearly detectable inside spider's body (I also had not known this clearness until editing video). The larva sucks spider's haemolymph from several parts of spider including legs and cephalothorax. After discarding dried spider carcass, the larva rested for a while and then moved upward and started weaving a cocoon. The larva changed head direction upward and downward many times inside the cocoon and daubed silks onto internal surface of the cocoon.
