formerly placed in subfamily Amphipyrinae (which currently contains a single genus: Amphipyra)
Explanation of Names
Amphipoea interoceanica (Smith, 1899)
Hydroecia interoceanica Smith, 1899
wingspan: 28-31 mm (Smith, 1899)
slightly smaller than American Ear Moth, which has a wingspan of 28-36 mm
virtually identical to American Ear Moth (A. americana) but slightly smaller with a stouter body, and the white filling in the reniform spot is limited to the distal two-thirds
mostly inland or "between the oceans" - in Canada from QC west to AB but not coastal provinces of NB or BC (occurs in Nova Scotia however), and adjacent parts of United States
commercial strawberry farms; fields, meadows
adults fly in July and August
larvae feed on leaves, stems, and fruit stalks of strawberry (Fragaria spp.) plus grasses and sedges
Life Cycle
eggs are laid in July on dead strawberry leaves; overwinters as an egg, which hatches in spring; larvae feed from May to July; one generation per year
See Also
American Ear Moth (Amphipoea americana) is very similar but slightly larger with a more slender body, and usually an orange-filled reniform spot (compare images of both species)
