Spider Hunting on Alligator Creek

by Eric Neubauer

Sorry to miss the last meeting, but it was prime (for January) wolf spider weather in the early evening and I had unfinished business down near Alligator Creek.

Two images are attached. Both are adult males and would be considered large wolf spiders with a body length approaching a half inch. One is Tigrosa georgicola, a common species around here. I’ve seen them near the creek several times.

The other [P111694] has been baffling me after I found the first one on New Year’s Eve. Field identification guidance is fairly well developed for the larger wolf spiders, but there were reasons for eliminating all of them. I’ve found three now, so the first wasn’t an oddity.

Originally, I thought it might be Alopecosa, which only has a few images on the internet. At present I’m thinking it might be a morph of the other species I found there, Tigrosa georgicola. If I was still taking typical wolf spider photos, that is dorsal views only that weren’t highly detailed, it would have ended up as “something in the Schizocosa ocreata species group” and that would be the end of it.

As it is now, I can’t get beyond subfamily Lycosinae but am favoring a rare morph of an existing Tigrosa species or much less likely an undescribed Tigrosa species. Considering all three were found in the same area, they could all be siblings. Their mother would be proud.

I suppose there could be another option: a hybrid of Tigrosa georgicola and Schizocosa perplexa but I’d think the two are too unrelated to produce offspring.
