Male Black Widow - Latrodectus variolus - Male
Pikes Peak, Brown County, Indiana, USA
May 16, 2012
Descended on me while sitting at my desk in my walk-out basement. I felt it brush my arm and then I jumped. No, I was not bitten. Found it 15-May-2012 and I'm still OK. I thought these prefered to be outside. Was it just a mistake it came in?

I am uncertain if it is northern or southern black widow.

Knew there was a reason I saved some petri dishes!

very neat
Latrodectus variolus. Males probably out looking for a girlfriend. Northern widows are less inclined to be around human habitations, but that certainly is not a rule. Other than the occasional transient, I am not sure if L. mactans is native to Indiana. mactans is found in Ohio and Illinois so there is no reason why mactans shouldn't be established in Indiana.
