X marks the spot. . .

Yesterday, we went back to flip the switch on the water tank for the hotel (yes, the water here is fine to drink, no worries) and came across this spider with its web. Very hard to miss, with the big white "X" right in the center of it. Went back to take some pictures, and the spider had moved to the other side of the X, so it's not visible in the shots. It's an Arigiope spider, for those who didn't know. I looked it up on the Web and had to wade through a surprisingly large amount of SpiderMan and Hulk sites to find something on it.

From Wikipedia:
The average orb web is practically invisible, and it is easy to blunder into one and end up covered with a sticky web. The very easily visible pattern of banded silk made by Argiope is pure white, and some species make an "X" form, or a zigzag type of web (often with a hollow center). The spider then aligns one pair of its legs with each of the four lines in the hollow "X," making a complete "X" of white lines with a very eye-catching spider colored bright yellow on a field of black or variegated red white and yellow stripes forming its center. The white patterns are called stabilimentum and reflect UV light. They have been shown to play a role in attracting prey to the web, and possibly to prevent its destruction by large animals
