Ectophasia is a genus of flies belonging to the family Tachinidae, commonly found in the Comunidad Valenciana and other parts of Europe.

Appearance: Ectophasia species are relatively small and are recognized by their distinctive appearance. They typically showcase metallic or dull coloration, often in shades of black, brown, or orange. The body is generally soft-bodied, with a robust and hairy appearance, which is characteristic of the Tachinidae family.

• Habitat: These flies are usually found in diverse habitats, including meadows, gardens, and woodland edges where they can access an abundance of flowers and plants.
• Diet: Adults mainly feed on nectar and pollen, playing a role in pollination. Larvae are parasitic, often targeting other insects.
• Behavior: The larvae of Ectophasia are parasitoids, meaning they develop inside a host organism, ultimately leading to the host's death. They predominantly parasitize Hemiptera, a group of insects often referred to as true bugs.
• Reproduction: Female flies lay their eggs on the host insect, and upon hatching, the larvae feed on their host from the inside.

In the Comunidad Valenciana, the ecological role of Ectophasia species contributes to natural pest control and pollination, making them a vital component of local biodiversity.
