Explanation of Names
Eupeodes americanus (Wiedemann 1830)
It can be grossly differentiated from Syrphus rectus by a dark stripe down the front of the face. The egg is ~0.96x0.26 mm, with broken longitudinal ridges. The larva is blackish with orange markings, looks somewhat spiky. The puparia is grayish-orange and appears mottled, much like the larva. First instars are difficult to separate if they were not seen emerging from an egg. (Short & Bergh 2003)(2)

Adults found in forests, fields, plantations, open areas, gardens, and sand dunes(1)
Larvae: wide variety of aphids, such as woolly apple aphid, rosy apple aphid and spirea aphid
