Comments & ID Thoughts

I'm assuming family: Thomisidae

Found it on an african violet in my kitchen.

Yes, I don’t know what Crab Spider it is specifically. Seeing it on an indoor plant flower that isn’t native led me to wonder how Crab Spiders recognize flowers. I found a study of whether it was sight or scent for the spider and the prey. The conclusion was that the spider appeared to choose the flower by scent and so did the spider’s prey. So, by scent the Crab Spider knew which flowers the favored prey would be attracted to. I think your spider was just settling for the first flower it could find.

Thanks very much. It may have translocation another (SC native) plant in my small greenhouse – perhaps from the pine mulch. Any guess as to genus?

I’m leaning towards Genus: Xysticus.
