Help ID this BTA

demetri · Jun 17, 2026

I have had this BTA for a while and I got it off of FBM.

I need help getting an id on the species of BTA.

I believe that it is a black widow as it matches the same colours and patterns while also having some blotchy white spots.

Please tell me what you think

Unfortunately, I'm not great at ID'ing 'nems, but I'm sure that another R2R member will be able to help

AFAIK, true Blackwidows lack the green and it’s more of the purple-black. But much like Fish Fan, I’m not the best at BTA IDs (I still haven’t managed an ID on my old green Nem which was given to me as a BTA).
