Observation notes: in wet parts of an alpine meadow. I am not sure of this ID. I have very little experience with frittilaries. It was very light orange in flight. photos are of the same individual. saw 2 or 3 of these.

Coordinator notes: Nice job correctly identifying this as the Mormon Fritillary, the only greater fritillary that inhabits the Colorado alpine. Some lesser fritillaries are also found in the alpine (mainly the Arctic Fritillary), but their ventral sides look completely different from the greater fritillaries'. Due to the harsh alpine climate, this species only has one flight in Colorado during the hottest part of the year, usually mid-July through early September. This individual is one of the year's earlier fliers.
