Monopis longella
(Walker, 1863)
Pavlovski's Monopis Moth
Monopis longella is a tineid with a broad Palearctic and Oriental distribution, now established as an introduced in eastern North America. Its larvae construct tubular tunnels in bird nests where they feed on keratinous materials. The species is notable for a distinctive mitochondrial arrangement that differs from typical lepidopteran patterns.

More Details
Mitochondrial genome
The complete mitochondrial is 15,541 and exhibits a unique gene arrangement among Lepidoptera, specifically a trnI-trnM-trnQ sequence in the A+T-rich region and at the ND2 junction. Uses ATT as the COI start rather than the typical CGA found in most Lepidoptera.
