Explanation of Names
Patronym for Dr. Thaddeus Wm. Harris, a great friend of Hentz.
Identification
The lattice like retreat is a key identifier of the species.

They also build two different types of orb web. One is the regular type, and the other is the Zygiella x-notata type, which can be seen on pg. 61 of the golden guide. The retreat is always the same, regardless of the web style.

"Observations. This species, which is sometimes whitish on the abdomen, is nevertheless very readily recognized. I have seen some specimens larger than the delineation. Its dwellingplace is really beautiful; it is placed above its web, and made of the finest white silk, shining with a satin lustre; its shape is that of an inverted thimble, and it is usually placed under a leaf bent together for the purpose of affording shelter and security." Nicholas Marcellus Hentz, M.D. 1847

Remarks
The female of this species can be confused with the white form of A. detrimentosus, but the venter markings are different. A. thaddeus venter looks like this:


Males are known to be confused with A. pegnia. A. pegnia males have a median apophysis with two apically directed teeth while A. thaddeus has three teeth of variable size.
