These are very pale yellow aphids with short, dark ‘tailpipes’ (cornicles). They are capable of very high rates of reproduction and produce copious amounts of honeydew. The sugarcane aphids seen in 2013 were gray to tan or light yellow. Unlike other common aphid species that feed on sorghum, sugarcane aphids have dark, paired, tailpipe-like structures, called cornicles, at the rear, and their tarsi (feet) are dark at high magnification. The dark cornicles and tarsi contrast distinctively with the lighter body color of the sugarcane aphid. Go to Texas A&M Agrilife Extension Publication (#ENTO-035) for more information.
