The genus Achaearanea Strand, 1929 (Theridiidae) is revised. Two genera, Henziectypus Archer, 1946 and Cryptachaea Archer, 1946, are revived from the synonymy of Achaearanea.
THE JOURNAL OF ARACHNOLOGY positive behavioral response to capture of prey. In contrast, Achaearanea tepidariorum (Theridiidae, three-dimensional web) appears to live in areas where prey are sometimes locally limiting, since most houses (natural habitat for this species) apparently have a high.
Parasteatoda tepidariorum eats insects, as do all spiders. It catches its prey by waiting in the web until a large insect, such as a Camel Cricket, gets caught in the sticky web. When this happens the spider proceeds to throw more silk onto its victim and then pulls it up into the web.

Achaearanea tepidariorum. The leg-bearing segments L1, L2, and L4 are missing after downregulation of At-hb via RNAi. At-hb is required for the correct organization of target genes in this region of the embryo, suggesting that At-hb acts as a gap gene in the spider. In contrast to insects, hb does not control Hox gene expression in the spider.

The cobweb spider Parasteatoda tepidariorum (C. L. Koch, 1841; syn.: Achaearanea tepidariorum) has become an important study organism in developmental biology and evolution as well as in genetics.
As its name suggests, the common house spider is the spider most often seen in homes in the United States. They like to build webs in hidden areas of the home, such as attics, basements, sheds, and barns. Most of the webs are in the corners of rooms and very easy to miss. The common house spider is.
Parasteatoda tepidariorum. Quite the same Wikipedia. Just better.
Web-spinning activity ofAchaearanea tepidarortum (Koch) was observed in relation to amount of prior feeding, hours of food deprivation, and the number of flies (Drosophila melanogaster) available in the animal’s environment. Web spinning was positively related to the number of flies consumed in a 24-h period prior to testing, but did not vary significantly between 24 and 72 h of food.
Achaearanea tepidariorum Theridium tepidariorum Parasteatoda tepidariorum, the common house spider, referred to internationally as the American house spider, is a spider species of the genus Parasteatoda that is mainly indigenous to the New World, with P. tepidariorum australis ( common gray house spider ) but has achieved a cosmopolitan distribution (1).
