Habitat

Found in open woodlands, forest edges, and prairies. are frequently observed on flowers of woody shrubs and trees, particularly Prunus and Amelanchier .

Distribution

Records from Europe (Denmark, Norway, Sweden) and North America (United States, including Vermont and Missouri).

Seasonality

are active in spring, with observations in April documented in Missouri.

Diet

feed on pollen of flowering plants. Specific plants include Prunus mexicana (Mexican plum) and Amelanchier arborea (downy serviceberry). Larval diet is unknown but presumed to involve decaying wood or plant material based on -level traits.

Host Associations

  • Prunus mexicana - pollen source observed feeding on flowers
  • Amelanchier arborea - pollen source observed feeding on flowers

Behavior

are and frequently found mating on flowers. They are active fliers and readily move between flowering plants.

Ecological Role

function as pollen feeders and likely contribute to pollination of early spring-blooming woody plants. Their role as larvae remains undocumented.
