    Western Spotted Orb Weaver - (Neoscona oaxacensis)

    The bold pattern on the Western Spotted Orb Weaver makes it easy to identify once you've seen it.

    Staff Writer (9/23/2014): Like all Orb Weavers, the Western Spotted Orb Weaver spins a circular web. This species tends to create them in open areas that aren't dense with foliage, making it easier for spider enthusiasts to spot them. The spider will sit in the center of the web, upside-down, waiting for insects to entangle themselves. Unlike most Orb Weavers, however, these spiders do not make any zigzag patterns in the center of their web called a stabilimentum.

    They feed on anything that entangles itself in their webs: flies, moths, beetles, mites, lice, etc. Look for them in open fields, empty lots, gardens and parks. Adults are seen in autumn, when eggs are laid. Spiderlings remain in their eggs over the winter and hatch in the spring.
