What bug do you this this is?

Question

I saw a bug working and ill discribe it.

It was bright red. I saw 2 in the same yard. It was about an inch long. Had 6 legs. 2 small black antenas. Segmented body sort of like an ant. I saw it walk through a spiderweb with no trouble and when the spider went to see what he caught he ran back to his corner (the spider was smaller than the bug) What do you think it was?

Answer 1

Sounds like velvet ant. Also called a cow killer ant. Check out the link below. There's a bunch of pictures if you search the net for them, but I'll go with just one.

Answer 2

Possibly a velvet ant, also called the deerkiller ant. it's actually a wasp with a very nasty sting. Here's a link with some pics and some Q&A
