Diet and breeding
Apolinar's wren forages by climbing up vegetation stems and then dropping to near ground or water level. The nominate appears to feed primarily on Chironomus midges but also spiders and other adult and larval insects.
C. A. Hernandezi appears to also feed on insects but details have not been published. The nominate Apolinar's wren appears to breed between February or March and October and might double-brood.
