spider with beelike abdomen?

There are a number of spiders that can mimic other bugs, or even vegetation for camouflage.

One spider even takes on the look of bird poop.

Shame you squished the poor thing, likely a harmless spider.

I would probably have kept it until I could identify it and read a little about it.

Spiders don't have stingers, they have spinnerets. some few have soft ovipositers that might look like a stinger or tail,too soft to pierce skin though.
