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
M. hutchinsoni are part of the Mastophora genus within the larger Araineida or orb-weaver family. They are in the Arthropoda phylum, the Arachnida class, and the Araneae order. [2] Originally stemming from normal orb weavers, the genus adopted an alternative web design (the bolas) and widely distributed throughout the world. [6]
The webs are found in trees, shrubs and tall weeds, and grasses in moist, wooded settings and can frequently be found along the banks of streams. [5] The webs are oriented vertically and have a "signal" thread attached to the center that notifies the spider when prey has been captured.
The neon yellow, orange or red spots on the rear of the abdomen are variable in size among individuals and sometimes absent. This species is parasitised by a wasp larva which attaches itself externally at the junction of the cephalothorax and abdomen.

They reside in a small orb web spun in a tree or shrub. The web is normally made on a leaf, and the leaf is then manipulated to become an easy trap. They can spin a large web sometimes between branches and stems. These tiny orb weavers can live in forests edges, field edges, or in woodlands.
The golden silk orb-weaver is named for the yellow color of the spider silk used to construct these webs. Yellow threads of their web shine like gold in sunlight. Carotenoids are the main contributors to this yellow color, but xanthurenic acid, two quinones, and an unknown compound may also aid in the color. [14]
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 ...
The Australian garden orb weaver spider (Hortophora transmarina) is a very common species of spider with many variants in size, shape, and colour across the coastal and northern regions of Australia. [1] [2] They have very large abdomens when well-fed and exhibit a tremendous colour-range from off-white through tan, brown to almost black. They ...
