Long-jawed Orb Weaver


Long-jawed Orb Weavers are named because of their large fangs, which are, in some species, longer than the spider’s cephalothorax (first body segment).

Like all spiders, babies hatch from eggs and look like tiny adults. They shed their skin as they grow. Most spiders in this family live for less than one year. They mate and lay eggs at the end of the Summer and the young spiders hatch during the following Spring.


Long-jawed Orb Weavers can have a two inch leg span and are skinny. Most are tan with white and yellow markings. They are common in low-growing vegetation and in row crops. I tend to see them at the edges of the Ohio & Erie Canal while hiking on the towpath. Below is a photo one one that I saw eating another of its own species.

To avoid being eaten by predators, they drop from their web at out at the slightest disturbance, or carefully camouflaging themselves by lining up with the long axis of a twig or grass blade.


Most members of this family do not build vertical webs, they are usually tilted and sometimes close to horizontal. The bizarre appearance of this creature with its over-sized mandibles makes it a favorite of mine.
