Trachypepla euryleucota is a moth of the Oecophoridae family. It is found in New Zealand. Adults have been recorded in December. They have been taken when the manuka (Leptospermum) was in blossom. It is thought that when adults sit at rest its white head, thorax, and basal portion of wings are of protective value by reason of their resemblance to an opening manuka-bud. Larvae have been found feeding on bird nest debris.
