During a recent morning walk at Occoquan Bay National Wildlife Refuge, I came across some spiderwebs in the fields that glistened in the sunlight thanks to rain the previous night. Many of the webs were only partial webs and I wondered if perhaps the torrential rain had ripped them apart.

Light was mostly coming from the front, which made it a little tricky to get a correct exposure, but that kind of backlighting is the reason why the webs are visible.

The backgrounds were different for the different webs and most of the time I had to deliberately underexpose the images to have the webs “pop,” which meant that the backgrounds looked really dark. I was thrilled when I managed to capture the first image below with a background full of autumn colors.

When this Spotted Orbweaver spider (Neoscona crucifera) spotted me last week at Jackson Miles Abbott Wetland Refuge, it scurried along the silken threads of its web to the relative safety of the plant to which one end of the web was attached.

There is something that really appeals to me about this image. Maybe it’s the way that the colors of the spider match those of the plant or how the shapes of the stems are similar to those of the spider’s legs. Perhaps it is the contrast between the sharpness of a few elements in the image and the dreamy, almost ghost-like background.

Most of the time I strive for super-realistic images and try to draw a viewer’s attention to the details. When I am in an artsy, creative mood, though, I am content to capture an impression of the subject, leaving the details to the imagination of others.

Raindrops can enhance the beauty of many subjects, like this spider web that I photographed on Friday at Occoquan Bay National Wildlife Refuge. As I looked at the drops, they somehow brought to mind an elaborate necklace of loosely strung pearls.

When you shoot with a zoom lens, you can change the look of an image without moving from where you are standing. That can be an advantage, but it can also be a disadvantage, because it can discourage you from exploring different angles or different perspectives.

I really enjoy shooting with a lens of a fixed focal length, especially my macro lens, because it forces me to think more about composition. If I decide that I want the subject to be larger in the frame, I have to move physically closer to the subject. If the terrain doesn’t let me get any closer, then I have to consciously consider how else I could frame the shot.

This past weekend I saw a lot of black and yellow garden spiders (Argiope aurantia) when I was exploring Jackson Miles Wetland Refuge, a small park not too far from where I live. Some of the spiders were in bushes and others were overhanging the water of a small pond. It was a fun challenge to figure out how to photograph the spiders in different and interesting ways.

In the first shot, I decided to shoot the spider from the side rather than from the front as I normally do. I was delighted to see the way the the shape of the vegetation in the background almost matched the shape of the spider’s legs.

I also photographed the spider in the second image from the side, but the leafy backdrop and the inclusion of more of the spider’s web gives the image a completely different feel as compared to the first one.

When I saw the spider in the third image overhanging the water, I loved the shape of its body and its extended legs. If I had had a zoom lens, I am pretty sure I would have zoomed in on the spider. When processing the image, I was also tempted to crop in closely. I remember when I was shooting, though, that I deliberately included the vegetation on the left hand side, because I liked the way that it looked. So the image that you see is pretty much the one that I chose when I shot it, having zoomed in as closely as my feet would allow (without getting really wet). Despite my normal desire to fill my frame with my subject, I think it was good that I was not able to do so in this case.

On Monday at Occoquan Bay National Wildlife Refuge I watched with fascination as this spider (maybe a Marbled Orbweaver (Araneus marmoreus) spider) worked on her web. She seemed to have started with the spokes coming out of the middle and was adding the ribs when I photographed her.

If you look closely in the first image, you can actually see the web material coming out of one of her spinnerets, the organs in which a spider produces the different kinds of silk that make up a web. I tried to figure our her process as I observed her. It looks like she would produce a length of silk, maneuver it into place on one of the spokes with one or more of her legs, affix it in place, and then start the process over again. For the final image, I moved back a little to give you a somewhat better view of more of the web and a sense of its shape.

I have photographed spiderwebs many times before, but this was the first time that I watched one being built. My admiration for the skills and artistry of spiders continues to grow—they are simply amazing.

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.

Unlike those that construct elaborate webs, some spiders instead perch at the shore with extended legs and sense prey through vibrations on the surface of the water. When the prey is detected, the spider runs across the top of the water, prompting some to call it the “Jesus spider.”

I spotted this cool-looking Six-spotted Fishing Spider (Dolomedes triton) in the shallow water of a pond this past Monday at Occoquan Bay National Wildlife Refuge.
