The Coconut Moth (Batrachedra arenosella) is a species of moth of the Batrachedridae family. It is found in India, Indonesia and Malaya as well as New Zealand and Australia, from the Northern Territory and northern Queensland to New South Wales and South Australia.

The wingspan is about 10 mm. Adults have forewings that are speckled brown, and that have fringes along the inner margin that are longer than the width of the rest of the wing. The hindwings are narrower, and have fringes along the costa and even longer ones along the inner margin. The antennae are longer than the forewings.

The larvae have been reported damaging flowers of coconut palms, but other records suggest the larvae feed on seeds of Juncus species or are predatory. Larvae have been found living in a webbing on a trunk of an Eucalyptus species and feeding on small scale insects living there.
