Found this creature inside my home 10/21/2017. Is this an immature female black widow? It had the red spots on the back and some on the abdomen. We also found this one the the porch in early October. Is it an orb weaver?
How you want your letter signed: J.E.
This is most certainly an immature, female Widow Spider, and considering your location, it is most likely an immature, female Northern Black Widow, Latrodectus variolus, which is pictured on BugGuide. Your other spider is indeed an Orbweaver.
