Dewdrop Spider

Smallish spider crawling in big spider webs of different spiders. They seem to be kleptoparasitic, steal food from them. There are a few of them in the same web. The big host spiders do actually mind, as I observed a pursuit, where the Dewdrop spider first tried to hide. The orb spider, repeatedly played some webstrings like a harp, approaching the tiny spider. When it was too close, the Dewdrop spider resorted to some abseiling and escaped. The totally silvery orb looking abdomen has a black stripe at the front.
