Green Page Moth: Costa Rica’s Dazzling Daytime Flier
Costa Rica is home to an incredible array of wildlife, including the dazzling Green Page Moth (Urania fulgens) also called the Urania Swallowtail Moth, a day-flying moth often mistaken for a butterfly.
Known for its striking colors and unique migration patterns, this moth captures the attention of nature enthusiasts and researchers alike.
Let’s explore 10 detailed facts about this incredible species:
1. A Master of Disguise: Butterfly or Moth?
This Swallowtail Moth is often confused with butterflies because of its vibrant colors and daytime activity. However, it’s a true moth belonging to the Uraniidae family.
2. Where to Spot Them in Costa Rica
Green Page Moths are frequently seen in lowland rainforests and along riverbanks in Costa Rica. Look for them in areas such as Corcovado National Park or La Selva Biological Station.
3. Stunning Iridescence
Their black wings are adorned with striking green and blue iridescent bands, making them a favorite subject for photographers and nature lovers.
4. Diurnal Behavior
Unlike most moths, this moth species is active during the day. This behavior, combined with its bold coloring, further distinguishes it from other moth species.
5. A Migratory Marvel
The Green Page Moth is one of the few moths known for its long-distance migrations. They follow specific flight paths, influenced by seasonal changes in their host plant availability.
6. Feeding Preferences
The caterpillars of Urania fulgens feed exclusively on plants of the genus Omphalea. Adults, on the other hand, sip nectar from flowers, contributing to pollination.
7. Toxicity as a Defense
The moth’s caterpillars absorb toxins from their host plants, rendering them toxic to predators. This natural defense mechanism is complemented by their bright coloration, warning predators to stay away.
8. A Witness to Rainforest Health
Because of their reliance on specific host plants, Green Page Moths are often considered indicators of ecosystem health. Their presence signifies a thriving rainforest.
9. A Short but Beautiful Life
Like most moths, Urania fulgens has a relatively short lifespan, with adults living only a few weeks. However, their vivid appearance leaves a lasting impression.
10. Conservation Importance
Preserving habitats where their host plants grow is critical to the conservation of the Green Page Moth. Supporting protected areas in Costa Rica ensures their survival for future generations.
The Green Page Moth (Urania fulgens) is a testament to the beauty and complexity of Costa Rica’s tropical rainforests.
Whether you’re exploring Costa Rica or admiring them from afar, the Green Page Moth is a reminder of the delicate balance that keeps our planet’s biodiversity thriving.
