Similar species

  • Erynnis brizo shows an overall darker appearance and is larger (wingspan 32 to 45 millimeters).
  • Erynnis marloyi and the red pea butterflies ( Erynnis day ) occur only in Europe and Asia and therefore have no geographical overlap with Erynnis icelus .

Distribution and occurrence

The range of the species stretches from the Northwest Territories eastward through southern Canada to Nova Scotia . Further south it was also detected as far as Arizona , New Mexico , Arkansas , Alabama and Georgia . Erynnis icelus prefers to colonize open forest landscapes and moist stream valleys.

Way of life

The moths fly in one generation a year, mostly in May and June. They suck on flowers to absorb nectar and absorb liquid and minerals from damp places in the earth. The caterpillars feed on the leaves of various willow ( Salix ), poplar ( Populus ) and birch species ( Betula ). They live in nests made of rolled and spun leaves. The adult caterpillars overwinter.
