Simosyrphus grandicornis, commonly known as the yellow-shouldered stout hoverfly, is an Australasian species of hoverfly, and is one of the two most common hoverflies in Australia, alongside Melangyna viridiceps . [1] It has been introduced to a number of Polynesian Islands as well as Hawaii. [2]

Eggs are laid near aphid colonies, as the prey of this species' larvae is mainly aphids. [3]

Description

S. grandicornis has a body length of 10 mm. It has yellow edges on the sides of the thorax and yellow antennae. It is named for its stout body shape. [3] The easiest way to differentiate the sexes is that females have their eyes separated at the top, whilst males have them touching. Females also have a slightly wider and rounder abdomen. [4]
