why are there dead spiders in a wasp's nest?

Question

As I was destroying several 6-8 inch long tubular wasp's nests in the southeastern us, I saw about two dozen dead? spiders lying on the porch.

Answer 1

From your description of the nest as tubular the
wasp was probably a mud dauber wasp of the
genus Trypoxylon. These build tubular mud nests
consisting of rows of cells placed end to end, with
several rows in contact with each other at the sides
in large nests.

The female wasp stings and paralyzes spiders and
places them in the cells as food for her larvae.
Each cell contains several paralyzed (not dead)
spiders and one wasp egg. The larva that hatches from the egg eats the spiders and pupates in the
cell.

There are other kinds of mud daubers which make
differently shaped nests, or use the old nests made by other wasps after the adults have emerged from them. All the mud daubers stock
the nests with spiders. Other kinds of wasps also
paralyze spiders as food for their larvae, but do
not build the mud nests, or, in some cases, any
nest at all.Some of them simply glue an egg to the
spider, usually on the top of the abdomen in front.
The spider, in this case, recovers from the
paralysis and goes about its business while the
wasp feeds a little at a time on its blood. Finally
the wasp eats the whole spider in a fairly short
time and pupates.

Answer 2

There are actually many species of solitary wasps that hunt spiders. They are also commonly known as spider wasps, spider hawks and various other common names. The adult wasps will tackle a spider they see that is of suitable size, and their formic acid which is injected with the sting, paralyzes the spider completely. The spiders are flown to the nest and preserved in these chambers. Before the chamber is sealed up, the female wasp will lay a single egg on the body of the spider. The spider is only paralyzed, so it is still alive when the larvae hatch, this guarantees freshness. The larvae will feed on the living body of this spider. They will molt through several instars and pupate. Once they are adult, they will chew their way out of their little chamber and go out in search of a mate and their own spider to feed their larvae. Good Question, I hope that helps!

Answer 3

Either food for the wasps, or more likely, food for the wasp's larvae -- I know of one species that sting the spider with a paralytic venom, then lay eggs in the spider's body so that when they hatch a day or two later, they have a nice, juicy carcass to eat while it's still alive. Gruesome, but that's life.

Answer 4

Your wasp is from the kin Sphecidae or Crabronidae, frequently popular because the dirt dauber. The dirt dauber wasp captures and paralyzes different insects and leaves piles of them in it is nests for it is offspring to feed upon even as they hatch. they're hardly aggressive yet I actual ought to assert, even in spite of the indisputable fact that they hardly sting, i locate them significantly better painful than the similar old wasp so be careful.

Answer 5

food

Answer 6

they are probably eating them
