Identification

Euphoria monticola is distinguished from the closely related Euphoria fulgida by its coloration: specimens are typically metallic -black rather than the metallic green or green-blue and burgundy coloration seen in E. fulgida. The was formally separated from E. fulgida based on morphological and geographic evidence in a 2012 revision of the .

Habitat

Found in mountainous regions, as suggested by the specific epithet "monticola" (mountain-dweller). In Arizona, it occurs in the mountains of the southeast part of the state. Associated with oak woodlands and mixed evergreen forests with understory shrubs including Gambel's Oak.

Distribution

Neotropical: Mexico (Aguascalientes, Chihuahua, Durango, Jalisco, Nayarit). Nearctic: United States (Arizona, New Mexico).

Seasonality

are active primarily in late spring and early summer. In Arizona, observed flying in June. In Colorado Springs area, adults most common in May and June, persisting into July. In Prescott, Arizona, reported active in mid-July.

Diet

feed on sap exuding from wounds on trees, especially oak (Quercus spp.). Also visit flowers for nectar and pollen, including dogwood, sumac, thistle, and other plants.

Host Associations

Quercus - food source feed on sap from wounds
Cornus - food sourceflowers visited for nectar

Life Cycle

with one-year . develop in soil, feeding on matter including manure and decaying material. Larvae enter quiescent pre-pupal stage in September-October and overwinter. occurs in spring, often under logs in moist . emerge in late spring and early summer.

Behavior

Ecological Role

Taxonomic History

Euphoria monticola was originally described by Bates in 1889. Specimens from the mountains of southeast Arizona were long treated as dark-colored variants of Euphoria fulgida. A 2012 revision by Jesus Orozco formally recognized E. monticola as a distinct based on morphological and geographic evidence. Similarly, Florida formerly assigned to E. fulgida were recognized as E. limbalis.
