Instead of stocking a nest cell with one or two large spiders, mud daubers cram as many as two dozen small spiders into a nest cell. To capture a spider, the wasp grabs it and stings it. The venom from the sting does not kill the spider, but paralyzes and preserves it so it can be transported and stored in the nest cell until consumed by the larva.
Many kleptoparasites are arthropods, especially bees and wasps, but including some true flies, dung beetles, bugs, and spiders. Cuckoo bees are specialized kleptoparasites which lay their eggs either on the pollen masses made by other bees, or on the insect hosts of parasitoid wasps .
Spiders have been used in studies which indicate that invertebrates may experience pain. Under natural conditions, orb-weaving spiders (Argiope spp.) undergo autotomy (self-amputation) if they are stung in a leg by wasps or bees. Under experimental conditions, when spiders were injected in the leg with bee or wasp venom, they shed this appendage.
A leaf-cutter bee showing abdominal scopa. Megachilidae is a cosmopolitan family of mostly solitary bees.Characteristic traits of this family are the restriction of their pollen-carrying structure (called a scopa) to the ventral surface of the abdomen (rather than mostly or exclusively on the hind legs as in other bee families), and their typically elongated labrum.

Orb-weaving spiders have also been known to take single wasps as prey outside the nest. Attacks on the entire nest are also common. Both opossums and golden-fronted woodpeckers have been seen dissecting a nest. Other dismembered nests have damage that is similar to the damage caused by the woodpeckers to the nests. [6]

The moose had managed to escape the bear's clutches and the bear wandered over to a meadow to graze. But that doesn't mean that Larson wasn't shaken by the experience.
These spiders have the ability to repair the nest since they rarely find the need to fully rebuild the threads. Most of the time, the first spider to emerge from the nest after rest observes the web and checks for any damage, and then the active female workers are responsible for the repair work.
