Tegenaria Domestica.

[zsiciarz]

It's it accurate to say that they are the same in appearance as the atrica?

Not really. Same family (and for a time they were in the same genus) but there are differences in the pattern on the abdomen as well as Tegenaria species having dark banding on their legs.

Mine that I have now only eats small insects so small that it's not enough to make it grow much. Seems the case with many true spiders. He grew right after I caught him but had been the same since. The abdomen stays small like he's malnutritioned
