“Species In The Spotlight” by Lieven Decrick, nature freak and administrator of Tephritidae on observations.be.
Tephritis vespertina is common in many gardens, but is only rarely spotted.
Near Common Cat’s-Ear or Hypochaeris radicata (plant in photo). Common Cat’s-Ear is the host plant of this fly. Tephritis vespertina is observed both in the surroundings as on the plant itself.
Tephritis vespertina belongs to the family of the fruit flies and is in size somewhere between a fruit fly and a house fly (3-4 mm). You can distinguish this species from other fruit flies by the widened, dark fork in the tip of the wing (see photo). The fork denotes the dark wing drawing on the tip of the wing, which is strikingly “wide and bold”, says Lieven Decrick.
