Today I'm presenting a few images of an unknown species of Long-Legged Fly found in our area. They can be easily find out on the upper surface of leaves, enjoying sunlight. The Long-Legged Flies or Dolichopodidae is a family of true flies in order, Diptera, consistes of more than 7,000 species. They are tiny flies with long legs and big eyes, having metallic green, blue or copper color bodies. These flies are predatory on smaller insects.
