A St. Andrews cross spider is hanging on its web in Nagaon District, Assam, India, on February 25, 2024. Not only do their bodies form the diagonal cross that gives them their name, but they also weave a white X into their webs with extra silk. This one has just begun to do so, as you can see at the top right and bottom left. (Photo by Anuwar Hazarika/NurPhoto/Rex Features/Shutterstock)
