This image presents two photographs taken at different times and angles. The top photograph captures green moss growing on a large wet pine log when illuminated by regular daylight near Pole Creek on North Wilderness Trail of Little Lake Creek Wilderness in Sam Houston National Forest north from Montgomery, Texas.

In contrast, the bottom photograph shows the same area exposed to ultraviolet (UV-A) blacklight at 365 nm. The UV-A light has caused the moss to fluoresce and emit a vibrant red glow, which is visible against the background of the pine log. This phenomenon highlights the unique properties of certain plants that can absorb and reflect specific wavelengths of light.

The combination of these two photographs provides a striking visual representation of how different lighting conditions can affect the appearance of natural environments. The contrast between the green moss under regular daylight and its red fluorescence under UV-A blacklight creates an intriguing scene, inviting viewers to explore the complexities of plant biology and the fascinating world of bioluminescence.
