Pale dorsal abdomen with a dark band around the sides. Some individuals have small, dark oval shaped spots on the abdomen. The cephalathorax and legs are orange or pale brown. The legs, particularly the hind legs, may be faintly banded. The female of this species can be confused with the white form of A. detrimentosus, but the venter markings have a yellowish blotch. 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. |

Webs are built in shrubs and tall herbaceous growth at the edge of the woods. The conspicuous silk retreat gives this spider its common name. The silken tube has a pattern of holes that resemble latticework. 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 dwelling place is really beautiful; it is placed above its web, and made of the finest white silk, shining with a satin luster; 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 |
