On Thursday I spotted this cool-looking Arrowhead Spider (Verrucosa arenata) , also known as a Triangle Orbweaver, at Occoquan Bay National Wildlife Refuge. This spider is one of the few known orbweavers that sits facing upwards in its web—all other species face downward.

Its distinctive triangle-shaped abdomen makes this species pretty easy to identify. If you look closely at the image, I think that you can see a couple of the spider’s large round eyes shining brightly in between several of the legs in the upper left portion of the spider’s body.

When you check out spider webs really carefully, you can often discover really cool-looking tiny spiders, like this Arrowhead Orb Weaver spider (Verrucosa arenata) that I spotted yesterday at Occoquan Bay National Wildlife Refuge. If you look really closely in between its uppermost legs, you can see some of its multiple eyes looking straight at you. Information on BugGuide.net indicates that this spider is unusual because it rests in the web with its head up, not head down like most other Orb Weavers.

It’s hard to get a sense of scale when you look at this image, but I’d estimate that this little spider was less than an inch in length (25 mm). It was hanging in the air in its web at the edge of a trail when I first spotted it. I was able to move in pretty close with my macro lens—unlike many other spiders, it did not scurry away to the edge of the web. Sharpness is always an issue when shooting at at close range, but my monopod helped to steady me enough to get a relatively sharp image.

You may not like spiders, but you have to admit that this is a cool-looking spider.

This past weekend I spotted an unusual-looking spider at Huntley Meadows Park. I took this shot from a distance, so I didn’t capture all of its wonderful details, but it looks to me like a Triangulate Orb Weaver spider (Verrucosa arenata), also known as an Arrowhead Spider.

The spider was hanging in mid-air, which helped a slight bit with focusing, but Arrowhead Spiders are less than a half inch in size (about one cm), so it was a bit of a challenge getting any kind of shot with my telephoto zoom lens extended to 600mm.
