A rusty spider wasp (Tachypompilus ferrugineus) paralyses a wetland giant wolf spider (Tigrosa helluo) in south Texas, USA

@bismuthcladbattleship submitted: Hi! I found this large wolf(???) spider on my sink and held onto her in a nice enclosure for a couple months before releasing her outside once the weather got warm. I also got to see her molt, after which she was a lovely rich black for a bit.

Found in the foothills of Colorado near Denver, would love a precise ID! She was about 2-2.5 inches in leg span :)

From another message from the submitter:

Hi! I submitted a few pictures of a big wolf spider the other day and asked for an ID cause I was stuck trying to find one, but that's cause I was looking in the wrong genuses I'm pretty sure. The above paper describes the genus Tigrosa which I was totally unfamiliar with. I think, based on morphology, the spider I sent is Tigrosa grandis. I would love to know your take, I'm not good at keying out bugs.... yay bug!!!

Thank you!

Spider ID - NE US:

This is def a wolf spider, most likely in the genus Tigrosa. family Lycosidae.

It can be hard to ID wolf spider down to species using photos, but this looks very much like Tigrosa annexa.

This species only lives in the southern part of what I would call the NE United States, so if you're further north, then it could be another species in that genus.
