Dichomeris acuminatus
(Staudinger, 1876)
Alfalfa Leaf Tier, Alfalfa Leaftier Moth
Dichomeris acuminatus is a small in the Gelechiidae, commonly known as the alfalfa leaf tier. It has an exceptionally broad distribution spanning multiple continents including Africa, Asia, Australia, Europe, and the Americas. The was first described by Otto Staudinger in 1876. Despite its suggesting association with alfalfa, the species appears to be a with a wide ecological given its range.
Distribution

Host Associations
- Alfalfa - implied by 'Alfalfa Leaf Tier' suggests larval feeding on Medicago sativa, though specific records in source material are limited

Taxonomic Note
The was originally described as Mesophleps acuminatus by Staudinger in 1876 and later transferred to the Dichomeris. The basionym Mesophleps acuminatus is still recognized in some databases.
Distribution Complexity
The extremely broad distribution of this , spanning Africa, Asia, Australia, Europe, and the Americas, suggests either exceptional capability, human-mediated transport, or possible cryptic requiring further taxonomic investigation.
