Not good to see spiders in shipped in produce as they may be invasive. Theridiidae family? Almost looks like a widow of some kind.


I did consider the invasive aspect. It isn’t a Black Widow that is native to New Hampshire.

We are confident that it appears to be a Black Widow if all ingredients came from USA . There isn’t any species in America that looks quite like it. There are similar foreign spiders in the same genus. There are two species of Black Widow that are native to NH.… Read more »


Likely Latrodectus hesperus (Western Black Widow) if the grapes originated in the US (from California for example).
