If by "redback spiders" you mean the kind of widow spiders that grow in Australia, they make the same kind of three-dimensional tangled filament webs that all the member of their Family make. Some other kinds of spiders make orb webs, sheet webs, etc.
Furrow spiders belong to the genus Larinioides.These spiders weave orb webs. No spiders that weave orb webs are dangerous to humans.
There are a number of different spiders called banana spiders. A common one in Texas and other warm climates is the golden silk orb-weaver. This spider make large webs.
No, funnel spiders do not weave traditional orb webs like other spiders. Instead, they construct funnel-shaped webs that act as a trap for catching prey. The spider waits at the narrow end of the funnel for vibrations that signal prey is near.
No. They do not prefer any compass direction. Some spiders make webs that face up. Many spiders make webs near to porch lights because these lights attract insects. Where the web goes, and which direction it faces (if it is not a messy tangle web like that of the black widow spiders) generally depends on where the spider can find appropriate supports from which to hang its web.
The nocturnal orb-weaving spider typically builds its web at night. These spiders are active during the night when their prey is more abundant and create intricate orb-shaped webs to capture insects.
There are many spiders. Two are tarantulas, and black widow spiders.
Yes, all spiders have glands which produce silk. Not all spiders build webs (orb, sheet, funnel or otherwise) but they all have the capability to make silk.
Orb Weaver spiders weave the traditional circular web that most people are familiar with. The webs vary in pattern, but usually have a small circle in the center with larger circles radiating out from the center, in rings. The rings are connected by thin strands of silk, and give the web the appearance of having multiple sections, divided into wedges.
It takes about one hour for a spider to construct an elaborate web of silk thread, called an orb web. An orb web consists of a series of roughly circular, concentric outlines, with spokes extending from a hub. Orb webs, which are most noticeable in the morning dew, are constructed by many species of spiders.
Common types of spiders found in Michigan include the wolf spider, orb-weaver spider, and cellar spider. Residents can identify these spiders by their physical characteristics such as size, color, and distinctive markings. Wolf spiders are large and hairy, orb-weaver spiders have a round body with intricate webs, and cellar spiders have long, thin legs and are commonly found in dark, damp areas.
Like other spiders they make a web to catch flying insects.
