A jumping spider that is eating can make for a great photographic subject. In the past, I have swatted a fly or caught another small insect and placed it near a jumping spider, about 1-2 centimeters away. More often than not, the spider will quickly go for the free meal. Once they start eating, they tend to stay in one spot, allowing for ample time to adjust your camera settings and composition. This can be particularly useful for close-up shots and focus stacking techniques in macro photography.
