Blueberry maggot

Rhagoletis mendax

Body length 3 to 4 mm; mostly black, thorax with conspicuous white spot at tip (scutellum) and a white stripe along each side; abdomen with fine white bands separating segments; wing length 3 to 4 mm, with conspicuous black bands. Accurate identification of R. mendax adults depends on careful measurement of wing band ratios, ovipositor length and other genitalia features. Morphological separation from other pomonella group species may not be possible in many cases
