Two Informative Sites on Widows

[Stormcrow]

The first one here has some great information, like the LD50 toxicity of Latrodectus and some keys that are flimsy at best. I catch and buy too many Widows that don't fit these narrow profiles.

And another one with alot accuracy including an ID key to Latrodectus variolus here.

You're welcome, sites like these have small amount of more information than the usual can be invaluble, despite even if slightly inaccurate.
