Ethmia heliomela is a moth in the Depressariidae family. It is found in Australia in southern Queensland and northern New South Wales. The wingspan is about 30 mm. The forewings are grey, with a satin sheen and two black dots. The hindwings are yellow with black tips. The larvae feed on Ehretia acuminata. They live in webs amongst the flowers of the host plant. Initially they feed on the flowers, but may also eat the leaves when they mature. They are dark green and black. Pupation takes pace under the bark.
