Orb Weaver


This morning my sister noticed a tiny little spider, only a few millimeters wide, sitting in its web. It was a type of orb weaver. It had built its web, which was only about the size of my palm, between a couple of bars of a railing. The spider was sitting in the center of the web, waiting for something small to come along and get caught.

One of my friends suggested throwing an ant into the web; he wanted to see the spider at work. We looked around, but couldn't find the slightest trace of an ant. I didn't really care - I had already seen plenty of spiders catch their food  - but my friend was not satisfied. He stuck the tip of his pocket knife gently into the web and jiggled it around. His efforts proved futile; the spider could tell it wasn't an insect and did not budge from his position at the center. My friend succeeded only in messing up the web.

The upper-left corner is where my friend put his pocketknife.
The entire web is only the size of my palm.
Soon my sister found a few ants. We were able to get one into the web, and this time we saw the spider act. It ran over to the ant, and tried to grab it and wrap it in web. The ant was struggling, however, and being as large as the spider, was a difficult prey. The spider kept running forward, backing away, and running forward while the ant kicked and struggled. Finally it managed to bundle up the ant, using sticky threads pulled from the web.

At this point, I was able to take a few photos of the spider. The top photo is a closeup of the spider from behind as it works on bundling the ant more securely. The next photo is of the web itself, with the spider ¼ of the way down; my camera didn't focus very well, so if you view the photo full-size the web looks a little blurry.

After that, another ant somehow got into the web. I don't know which of us put it in, but one of us must have; I don't think it got there itself. The spider bundled up that one, too. After that, it looked like it started eating the ants, but I'm not sure; the spider was rather small and hard to see.

I enjoyed my experience with the spider. I can't say it taught me anything, because I had already closely observed other spiders' - especially orb weavers' - behaviors; however it was very interesting to observe it again. I'll end with a question inspired by my friend: what if a spider were a vegetarian?

2014 in Photos

The year of 2014 is over; the year of 2015 has begun. Over the past year, I took a lot of pictures - more than 1200 photos of clouds, bugs, plants, rocks, and more. I deleted most of the low-quality and repetitive photos. Then, I selected 20 of the remaining photos which I thought were the most interesting or significant. In this post, I'll include those photos, in chronological order. Spring 1. Cold Hummingbird I took this photo after a late snowstorm in Spring. In the days leading up to the storm, it was warm and sunny and the fields were green, so the snow came rather unexpectedly. During the storm, one of the hummingbirds at our feeder was covered in ice and could barely fly. This hummingbird was more fortunate, but unlucky nevertheless. 2. Green Landscape I took this photo on the side of a biking trail. I didn't edit or crop the photo - this is how it looked. 3. Indian Paintbrush The Indian Paintbrush is an unusual flower. What appear to be flower petals are actually brigh...

Major Change of Ideas

Edit: April Fool's. The article completely fails to answer for the benefits of math and science (including medicine and natural disaster prediction). It grossly exaggerates the negative aspects of math and science. Incidentally, math and science have made a large positive difference in my life. Good morning, everybody! I decided to write a blog post to say that I will be completely changing the way I view knowledge and the purpose of life. Photo credit: my sister Basically, "higher" knowledge (including logic, science, mathematics, etc.) is completely useless. There is no point in learning these subjects, which is why I have dropped all my college classes and will not be going to school today. Instead, we should go to the fields, with a shovel and a rake, and grow crops. I will therefore end my blog and begin life as a worker at a ranch in Wyoming. Why this sudden change, you might ask? A few days after my last post (which nobody seemed to read), I came upon a realizatio...
