Helophilus trivittatus (Fabricius, 1805) - Citroenpendelvlieg.

            Helophilus trivittatus has a wing length of 10.25–12.25 millimetres (0.404–0.482 in). The eyes are separated in both sexes, in the male a little less than in the female. The antennae are black, Face shows a wide yellow longitudinal stripe, with at most a central reddish-brown stripe. On the thorax four narrow pale yellow stripes alternate with three larger dark brown stripes. The drawing of the flattened abdomen is reminiscent of a wasp.
The drawing of the third and fourth segments of the abdomen is different in the two sexes. In the male, only the third segment carries a pale yellow to gray arc line. In the female, such a curve is found on the fourth and the fifth tergite. Tergites 2 and 3 have pale lemon yellow spots, while tergite 4 has white to grey spots. In the females tergite 3 yellow spots touch the front margin. The larva is illustrated by Hartley (1961)

Deze 12 tot 18 millimeter lange soort lijkt wat op de 'gewone' pendelzweefvlieg (Helophilus pendulus), maar wordt groter, heeft grotere en lichtere gele vlekken op het achterlijf en het achterlijf is ook meer langwerpig van vorm. Ook de vlekken op het achterlijf wijken iets af; die op het derde achterlijfssegment zijn witter en raken elkaar, bij de pendelzweefvlieg zijn er ook twee oranje vlekken op het achterlijf aanwezig en de dwarsstrepen op het derde segment raken elkaar. Beide soorten hebben een in de lengte gestreept borststuk. In Nederland en België is de 'gewone'pendelzweefvlieg algemener. De citroenpendelzweefvlieg lijkt wat op een wesp, maar mist een taille, heeft twee vleugels in plaats van vier en meer ronde ogen in plaats van langwerpige ogen. Bij de meeste zweefvliegen is het geslachtsonderscheid eenvoudig vanwege de ogen die bij mannetjes tegen elkaar liggen, bij vrouwtjes uit elkaar. Bij deze soort is dat echter niet het geval, wel heeft een mannetje een iets smaller achterlijf.
