The spiny orb-weaving spiders in the genera Gasteracantha and Micrathena look like plant seeds or thorns hanging in their orb-webs. Some species of Gasteracantha have very long, horn-like spines protruding from their abdomens. One feature of the webs of some orb-weavers is the stabilimentum, a
Male N. arabesca can often be found in nearby foliage or hunting on the ground. [4] Arabesque Orbweaver (Neoscona arabesca) Arabesque orb-weavers are, like any other orb-weaver, non-aggressive spiders. Only in rare cases, where the spider feels threatened, bites to humans or pets occur.
Nephila spiders vary from reddish to greenish yellow in color with distinctive whiteness on the cephalothorax and the beginning of the abdomen. Like many species of the superfamily Araneoidea, most of them have striped legs specialized for weaving (where their tips point inward, rather than outward as is the case with many wandering spiders).
Sexual dimorphism exists in Salsa fuliginata, where the females are generally larger than the male like most spiders. [7] Characteristics of female carapace and chelicerae are similar to male's with only one difference where three retromarginal teeth are of similar size in females. [ 5 ]
Araneus quadratus, the four-spot orb-weaver, is a common orb-weaver spider found in Europe and Central Asia, and as far as the Kamchatka Peninsula and Japan. [1] Females can reach 17 mm in length, especially when gravid, with males around half that. They are quite variable in appearance, ranging from brown to bright orange or green, but they ...
Gasteracantha is a genus of orb-weaver spiders first named by Carl Jakob Sundevall in 1833. [2] Species of the genus are known as spiny-backed orb-weavers, spiny orb-weavers, or spiny spiders. The females of most species are brightly colored with six prominent spines on their broad, hardened, shell-like abdomens.
The spider species Araneus diadematus is commonly called the European garden spider, cross orbweaver, diadem spider, orangie, cross spider, and crowned orb weaver. It is sometimes called the pumpkin spider , [ 2 ] although this name is also used for a different species, Araneus marmoreus . [ 3 ]
The barn spider (Araneus cavaticus) is a common orb-weaver spider native to North America. They are around three-quarters of an inch (20 mm) in length and are usually yellow and brown in color. They often construct their webs in wooden human structures, hence their common name.
