Description/ Field Marks: See Powell (1969) and Davis & Medeiros (2003). Similar Species: Adela eldorada Powell, 1969 is best distinguished by habitat: forests and chaparral for eldorada; meadows and grassy hillsides, frequently on flowers, for trigrapha. DNA barcode cannot at present be used to separate the two species. At present, they form a complex which includes six BIN groups narrowly separated by DNA barcoded, suggesting the possibility of undescribed species or alternatively a single species with several subspecies (Steve Nanz, pers. comm., 2024). Pinned specimens of related species. (Hint: select View by Region on the related species page.) Synonymy: trigrapha Zeller, 1876 (Adela) - MONA 1983: 0225 fasciella Chambers, 1876 (Adela) flammeusella of authors; not Chambers, 1876 (Adela) misappl. trifasciella Chambers, 1876 (Adela)
