The aphid Sipha maydis (Passerini, 1860) was observed on a volunteer wheat plant next to a wheat field in the Swartland area (S33.322239° E18.626311°) (Fig. 1) of the Western Cape, South Africa on 25 July 2018. Sipha maydis is a grass-feeding aphid distributed within its native range in Europe, Asia and parts of Africa (Bonnemaison 1980). It is widespread in eastern Europe, in the former Soviet Union, northwest India, Near East (Israel, Lebanon) and North Africa (Morocco) and southern Africa (Mozambique and South Africa) (El-Yamani & Hill 1991). Sipha maydis was first reported in Argentina in 2002 (Delfino 2002) and was found in the main cereal-producing region of Argentina in Bahia Blanca during 2004 (Ricci & Kahan 2004). Sipha maydis was discovered on wild rice in North America in California in 2007 (Sorensen 2007) and was reported on wheat in a greenhouse in Georgia in 2012 (Halbert et al. 2013). This aphid was also reported on an oat cover crop, along the edge of a winter wheat field, in New Mexico (Hammon 2015), on winter annual grasses in Colorado (Hammon 2015), on Johnsongrass in Alabama (Chambliss 2015), and on a rye cover crop in South Carolina (Villanueva 2016).
