Agonopterix propinquella is a species of moth of the family Depressariidae. It is found in Europe. The wingspan is 16–19 mm. Adults are on wing from September to July depending on the location. The larvae feed on Arctium, Carduus, Centaurea, Cirsium arvense, Cirsium vulgare, Cynara, Mycelis muralis and Serratula. They initially mine the leaves of their host plant. The mine has the form of a short, full depth corridor. After mining, the larva vacates the mine and continues window feeding from within a spinning along the midrib at the leaf underside. Larvae can be found from July to early August. They are apple green with a black head.
