Metzneria aestivella is a moth of the Gelechiidae family. It is found in most of Europe, except Iceland, Norway, Lithuania, Slovakia and Ukraine. The habitat consists of dry, sunny areas with low-growing herbaceous plants. The wingspan is 11–15 mm. Adults are similar to Metzneria lappella and Metzneria metzneriella but lack the black discal spot on the forewing. Adults are on wing from June to July.
