Araneus gemmoides Araneus gemmoides Araneus gemmoides, commonly known as the jewel spider (a name shared with "Austracantha minax") and cat-faced spider (a name shared with "Araneus gemma"), is a common outdoor orb-weaver spider found in the USA and Canada. They are considered harmless and have low-toxicity venom. "A. gemmoides" are useful natural predators for insects. "A. gemmoides" make their webs near lights, closed spaces, and on the sides of buildings. They can also be found under wood, overhangs, or guarded places such as animal burrows. They come in varying colors but are easily identified by the two horn shaped growths on their

Koch, 1877 as "Theridion gemmosum"), Titanoecidae ("Nurscia albomaculata", described by Lucas, 1846 as "Epeira albo-maculata") and Uloboridae ("Uloborus glomosus", described by Walckenaer, 1842 as "Epeira glomosus"). "Epeira cylindrica" was at a time placed in Linyphiidae and is considered "incertae sedis", as is ""Araneus" cylindriformis" . "Epeira" was synonymized with the genus "Aranea" by Leach, 1815, and with "Araneus" by Simon, 1904. Throughout the 19th century, "Epeira" was used as a catch-all genus, similar to the once ubiquitous salticid genus "Attus". However, from 1911, to its last mention in 1957, only very few authors continued
