Monochroa fragariae
(Busck, 1919)
strawberry crown miner moth
Monochroa fragariae is a small gelechiid described by August Busck in 1919. The is known from the Pacific Northwest of North America, specifically Oregon and British Columbia. Its derives from its association with strawberry plants, where the larvae mine the root crowns. The species is one of relatively few in the Monochroa with documented plant relationships.

Identification
The combination of small size (12 mm wingspan), dark fuscous forewings with yellowish overlay, and the characteristic spot pattern on the forewing distinguishes this . The more defined black spot at the end of the cell and the yellowish costal streak are key features. Similar Monochroa species may lack the distinct terminal cell spot or show different forewing maculation patterns; examination of genitalia may be required for definitive identification.
Habitat
Associated with strawberry and wild Fragaria . Specific microhabitat details are poorly documented, but the occurs in areas supporting its plants.
Distribution
Recorded from Oregon and British Columbia in western North America. Distribution records suggest a Pacific Northwest range centered on the Cascadian biogeographic region.
Diet
Larvae feed on root crowns of Fragaria (strawberries).
Host Associations
- Fragaria - larval food plantRoot crowns specifically
Human Relevance
Potential pest of cultivated strawberries due to larval mining of root crowns, though economic significance is not well documented.
