This film deals with food care concerning Theridion impressum (family Theridiidae). Most interest is given to the different ways of food supply: The females feed their spiderlings by reguration; the young ones approach to the mouth of their mother and suck a juice produced in the intestine. Later the female catches an insect and delivers her prey to the brood. At the end she dies and serves herself as food reservoir.
