On the night of March 13–14, 2025, skywatchers in Thermopolis, Wyoming, will have the opportunity to witness a total lunar eclipse, often referred to as a “Blood Moon” due to the reddish hue the Moon takes on during the event. This phenomenon occurs when the Earth comes directly between the Sun and the Moon, casting Earth’s shadow over the lunar surface.

The “Blood Worm Moon”:
The March full moon is traditionally known as the “Worm Moon,” a name rooted in Native American and colonial American folklore. This designation signifies the time of year when the ground begins to thaw, and earthworms become active, marking the onset of spring. When a total lunar eclipse coincides with the Worm Moon, it earns the moniker “Blood Worm Moon,” combining the reddish appearance of the eclipse with the seasonal name. (Wyoming Public Media)
Impact on Fly Fishing:
Anglers often consider lunar phases when planning fishing trips, as fish behavior can be influenced by the moon’s position and illumination. The solunar theory suggests that fish and other animals are more active during specific times related to the moon’s position. (Wikipedia.com)
However, the direct impact of a lunar eclipse on fish behavior, particularly in freshwater environments like those around Thermopolis, is not well-documented. Unlike solar eclipses, which can cause sudden changes in light and temperature, a lunar eclipse occurs at night and involves more subtle changes in illumination. Some anglers believe that nocturnal predators, such as brown trout, might become more active during the darker conditions of a total lunar eclipse, potentially improving fly fishing opportunities. Conversely, other fish may reduce activity due to the decreased light. Overall, while the lunar eclipse presents a unique nighttime environment, its specific effects on fly fishing are unpredictable and likely minimal.
Conclusion:
The total lunar eclipse on March 13–14, 2025, offers residents of Thermopolis, Wyoming, a chance to observe a captivating celestial event. While the phenomenon is steeped in cultural significance and natural beauty, its direct influence on fly fishing remains uncertain. Anglers may choose to experiment during this period, but should temper expectations regarding any notable changes in fish behavior.
