these from Trochosa there are slight differences in the abdominal pattern and I note that the median carapace stripe is narrow and continues between the eyes and down onto the face but it stops short on Trochosa.

Trochosa terricola

Trochosa ruricola

Tigrosa helluo

While I see the characteristic that you are looking at (pale, thin midline extending between the eyes), the width of the pale midline seems too broad for Tigrosa and the presence of the two dark longitudinal marks within the pale midline seem contradictory. Is the suite of observable characteristics consistent enough to move this specimen to genus?

The same double longitudal marks as Trochosa. On it’s own it’s an unreliable field mark for Trochosa. These are Tigrosa helluo spiderlings:


Some mature Tigrosa have them too, particularly T. annexa.

ruricola and terricola look for a cardiac mark that has lighter coloration than the rest of the abdomen (keeping in mind some Arctosa also have that feature).

All with extra brackets along median carapace stripe -
Light cardiac marks T. terricola and T. ruricola:

Medium to dark cardiac marks for T. helluo and T. annexa:

Thanks for the extra time to assemble all this. I appreciate you taking the time to teach me something new.

information, photos and descriptions, ought to be someplace on BG with more exposure that just this post but I'm not sure where (or how to do it). It's too informative to be hidden here.
Thank you very much!

for the added descriptive information.

You may have noticed I didn't even take it to family and it wasn't because I didn't try. I did settle on Wolf Spider but still was not sure. But then I'm the person who said, more than once, I'll never do spiders (not because they aren't way cool but because they're one more thing.)

They are fascinating! (but they are hard) One thing I try to get folks to do is night meander in August with a head lamp and be overwhelmed with green eyes everywhere.

I know the feeling. Sometimes I find it very difficult to refrain from getting involved with other taxa. How many loves can you have in your life?
