I was on my allotment this morning in the
nice warm sunshine and noticed hundreds
of spiders running around all over the ground.

They are cute aren't they?

Are these spiders the same as the ones that
live in my house, my shed, etc?

No.

And can I hope that they will eat the flies and
bugs that live off my vegetables?

They will take some, all spiders are useful and beneficial. But you
need a good selection of other predators including ladybirds and
lacewings as well.
