Quick Summary

The term "mandibulate moth" refers to a specific group of primitive moths belonging to the family Micropterigidae. Unlike most adult moths, these possess functional mandibles, which are chewing mouthparts. This characteristic is retained from their larval stage, where chewing mouthparts are standard for consuming plant material.12

Adult mandibulate moths primarily feed on pollen, while their larvae consume mosses and liverworts. This primitive trait of having chewing mouthparts in adults is a key feature that distinguishes them from more advanced moths, where mandibles are typically reduced or absent, and adults feed on liquids via a proboscis. Mandibulate moths are found in both the Northern Hemisphere and Australia and New Zealand.3145
