About Chilenocaecilius ornatipennis (Blanchard, 1851)
Chilenocaecilius ornatipennis is a medium-sized barkfly, with a body length ranging from 3.5–4 mm (0.14–0.16 in). Its general body color varies from yellowish-white to medium brown. A band of reddish-brown hypodermal pigment on the head stretches from the inner side of the antennal socket to the compound eye, and a relatively small, dark brown ocellar tubercle is also present. The thoracic pleura have a broad longitudinal band of red-brown hypodermal pigment. This species is always macropterous, meaning it has long, fully developed wings. It has a distinctive wing pattern with dark smudges at the points where wing veins meet the wing edge. Vein Cu2 (the posterior cubitus vein CuP in the forewing) lacks setae and is bare. This species is native to South America; it is widespread across Chile, and has two known localities in Argentina. It has also been introduced outside its native range to the United Kingdom, Ireland, and France. It inhabits the foliage of a wide variety of vegetation, and recorded populations occur at altitudes up to 1,000 m (3,300 ft) above sea level. While Chilenocaecilius ornatipennis can reproduce sexually, most populations lack males and reproduce via parthenogenesis.
