Polyommatus bellargus, commonly known as the Adonis Blue, is a striking butterfly species belonging to the Lycaenidae family. It is renowned for its vivid coloration and can be observed across various parts of Europe, including the Comunidad Valenciana.

The Adonis Blue is particularly recognizable due to its vibrant blue wings, which are more pronounced in males, while females typically display a more subdued brown coloration with slight blue hints. Both sexes feature a row of white-rimmed black spots along the edges of their wings.

In the natural habitats of the Comunidad Valenciana, Adonis Blue butterflies are often found in chalk or limestone grasslands, thriving in warm, sunny conditions. They are usually seen from late spring to early fall.

• Wingspan: Approximately 30-38 mm
• Flight Period: May to September, with a peak in July
• Habitats: Chalk grasslands, meadows, and hillside areas
• Caterpillar Food Plants: Primarily horseshoe vetch (Hippocrepis comosa)

The conservation of Polyommatus bellargus is significant, as it plays an essential role in local ecosystems. Their presence is often indicative of high-quality natural habitats, making them a valuable indicator species for environmental monitoring.
