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. If any were to get loose here they would find it difficult to find one of our two native Black Widow species to mate with. They allegedly live here, but I can’t find anyone who has seen one here. It’s too cold here for many non-native species. Being too cold also means there aren’t many insects around in Winter for them to eat. Insects that come into the state on imported wood is our biggest invasive species introduction threat. There is a ban… Read more »

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).
