Anoecia corni

Common dogwood-grass aphid

Description

Anoecia corni, commonly known as the Common dogwood-grass aphid, is a widespread aphid species found across Europe, Asia, North Africa, and both North and South America. These aphids exhibit distinct seasonal variations in their appearance and host plants. In the spring, the apterous fundatrices, which are dark brown or blackish, lay their eggs on dogwood trees (Cornus). Subsequent generations emerge and they migrate onto grasses. During migration, winged forms display a striking black pterostigmal spot on their forewings. While native to Europe, this aphid has also been introduced to North America. Its life cycle involves laying eggs on dogwood trees, followed by alate aphids flying onto grasses during the summer.
