Spider Photos -  Triangulate Orbweaver

Here's some photos of those common Garden spiders from the Orb Weaving family.   My apologies if there are some Araneus on pages where they don't belong but they are very hard to classify. Try this page for a species guide:
Orb weavers (Araneidae) are often brightly coloured with rounded abdomens, some with peculiarly angled humps or spines. However, there is considerable variation in size, colour and shape in this group. They are often recognized for building beautiful, large, round webs, on which they rest, head downward, waiting for prey. The webs consist of a number of radiating threads crossed by two spirals. The inner spiral begins in the centre, winds outward, and is made of smooth threads like the radiating threads. It covers only the central 1/3 of the web. The outer spiral begins at the edges and winds inward. It is made of more elastic, sticky threads, coated with a liquid substance. One of the largest and most commonly encountered members of this group is Argiope aurantia, the yellow garden spider and we have photos of them on their own page. Garden Orb Weavers are NOT dangerous (but can bite as can most spiders) and rid your garden of many unwanted insects. They only live for one season and die off as Winter approaches, leaving their egg sacs behind to hatch out next Spring. Please select a section below.

Status:   This species is sometimes called the "arrowhead spider." The genus name, Verrucosa, means "warty" and refers to the small wartlike bumps on the abdomen. This is the only species of Verrucosa in the United States. They are members of the garden orb weaver family (araneus).

ate summer and fall woodland hikers can count on walking into this small spider's web. Its wheel-shaped web is small and delicate and generally positioned vertically. This orb weaver probably is less common than the spiny-bellied orb weaver, but it is just as strikingly coloured and shaped. On females, the carapace (head) is glossy chocolate brown and small compared to the similarly colored, triangular abdomen. A triangle of colour almost completely covers the top of the abdomen, with the bottom angle pointing away from the spider's head; this triangle resembles a white, pink, or yellow flattened drop of shiny glue. This species rests centered in its web head-up instead of head-down, and the legs are often folded up against the body. Males are smaller and don't look very much like the females, as they lack the characteristic triangle on the abdomen. Males are rarely seen unless they are in a female's web either courting or mating with her.
Size:  Length (not including legs): 3/8 inch
Habitat and conservation:
The triangulate orb weaver's habits are similar to those of the spiny-bellied orb weaver, Micrathena gracilis. Most commonly seen in the woods in late summer and early fall. The females take advantage of the open areas of hiking trails, which flying insects -  their prey - use as trails, too. Also often seen in yards and other places where trees and bushes create appropriate open areas for them to spin their circular webs.
 Orb weavers typically capture insects in the sticky strands of their webs, then deliver a bite of venom sufficient to subdue and to begin digesting the insides of the insect. Then they wait, returning to the prey to ingest its liquified contents. The close spacing of the circles in the webs of this species enables them to specialize in tiny flying insects such as mosquitoes. They are ferocious predators to small insects, but they are completely harmless to humans.

Life cycle:   As a general rule, spiderlings hatch from eggs in spring and spend the growing season eating, maturing, mating, and laying eggs. Females are capable of creating webs; males are not. Females continue creating egg cases as long as the weather holds out. As temperatures cool in fall, their metabolism slows, and they generally die when it freezes. Egg cases overwinter, and spiderlings hatch in spring.

I was sitting in my house at my desk and noticed this little spider. It has light brown and black legs. Something light grey or silver on its back. Its playing dead. I caught it. If it's not poisonous I want to free it outside in the woods. Thank you for your help!
