Busck, 1900
Metriochroa psychotriella is a minute in the Gracillariidae. The is known only from Florida, United States. Its larvae are leaf miners that develop inside the foliage of Psychotria species.

Identification
are small, nondescript typical of the Metriochroa. The is most readily recognized by its association with Psychotria plants and the distinctive serpentine or blotch mines produced by its larvae. Definitive identification requires examination of genitalia or molecular analysis.
Habitat
Occurs in subtropical and tropical in Florida where plants Psychotria nervosa and Psychotria undata grow. These plants are typically found in hammocks, coastal strands, and disturbed sites with sufficient moisture.
Distribution
to Florida, United States. Records are concentrated in peninsular Florida.
Diet
Larvae feed on Psychotria nervosa and Psychotria undata (Rubiaceae). They mine the mesophyll of leaves, creating internal feeding tunnels.
Host Associations
- Psychotria nervosa - larval food plant
- Psychotria undata - larval food plant
Life Cycle
Complete with , larva, pupa, and stages. Larvae develop as leaf miners inside plant foliage. likely occurs within the mine or in a silken cocoon on the leaf surface, though this has not been explicitly documented.
Behavior
Larvae are endophagous leaf miners. are presumably and attracted to light, as is typical for Gracillariidae.
Ecological Role
As a , the contributes to herbivore pressure on Psychotria . It may serve as prey for and other natural enemies, though specific relationships are undocumented.
Human Relevance
No known economic or medical significance. Occasionally encountered by botanists and entomologists studying Florida's native flora and fauna.
Similar Taxa
- Other Metriochroa speciesSeveral occur in Florida and elsewhere; distinguished by plant association and subtle morphological differences in genitalia.
- Phyllocnistis speciesAlso Gracillariidae leaf miners with similar habits; Phyllocnistis typically produce more linear, epidermal mines and often have different preferences.
