The Return of the Full ‘Worm Moon’: What Does It Signify?

The full Worm Moon reached its peak this morning around 5 am, sparking curiosity about its meaning and origins. The first full moon of the spring season will appear on the nights of Sunday, March 24, and Monday, March 25. Specifically, March’s full worm moon reaches peak illumination at 3:00 am on Monday, March 25, 2024. If you miss the peak time, you can still catch a glimpse of the bright moon as it rises above the horizon on Sunday evening. If the weather is poor on Sunday night, try again on Monday to see the Moon in all its glory.

Moonbows are a rare phenomenon that can be spotted during a full moon when there are water droplets in the air, creating a rainbow effect. This March Moon will appear larger when near the horizon due to the Moon illusion. The name ‘Worm Moon’ comes from Native American tribes, specifically the Naudowessie (Dakota), who referred to a different kind of worm – beetle larvae that emerge from winter hideouts at this time. These larvae attract birds like robins, indicating the arrival of spring.

There are alternative names for March’s full Moon that signify the transition from winter to spring. Some refer to the return of certain animals, such as the Eagle Moon, Goose Moon, and Crow Comes Back Moon. Others highlight signs of the season, such as the Sugar Moon marking the flowing of sugar maple sap and the Wind Strong Moon representing windy days. The Sore Eyes Moon refers to the blinding sunlight reflecting off late winter’s melting snow.

The full moon names come from various sources, including Native American, Colonial American, and European traditions. Originally, each full moon name applied to the entire lunar month, not just the full Moon itself. While the name ‘Worm Moon’ was initially believed to refer to earthworms appearing in spring, further research revealed its association with beetle larvae emerging during this time. This phenomenon attracts birds and signals the change of season.

March’s full worm moon offers a unique opportunity to witness the beauty of a moonbow and experience the Moon illusion. Whether you catch a glimpse of the moon rise on Sunday evening or wait until the peak illumination time early Monday morning, take a moment to appreciate the magic of the natural world. The various names for the March Moon reflect the diverse cultural significance attached to this celestial event, marking the transition from the cold winter months to the vibrant renewal of spring.
