Spider was located in a messy web between two pots on my front step. Size was between 0.25”-0.5” in length. I witnessed an adult black widow in this location 8 months prior. I have witnessed adult brown widows on the adjacent wall of the home. This appears to be a juvenile of one of those species. Any help would be appreciated.
