Araneus marmoreus spiders, "Araneus marmoreus" hides in a silken retreat to the side of the web (at the end of the signal thread). In adults, the retreat is made of leaves folded over and held together with silk. Immature spiders make their retreats out of silk only. Egg cocoons, which contain several hundred eggs, are generally deposited in October and are constructed of white silk formed in a flattened sphere. Immature spiders emerge from the cocoons in spring. Adults are seen from midsummer until the first hard freeze of fall. Like other orbweavers, the marbled orbweaver is not considered a medically important
Araneus Theridiosomatidae ("Theridiosoma gemmosum", described by L. 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
