Yeah. They're spiders. I think they're somehow related to black widows, but basically they're small, shiny and black with a red stripe down their back. Oh, and they're deadly. We get them all the time in summer.
Spiders are fascinating creatures. I was bitten by a wolfspider once (while I was trying to transport it to a more hospitable environment - i.e. Outside). Insects are so ungrateful. Since then my fascination has greatly diminished.
