Olympia Marble
Euchloe olympia

Observation date: May 06, 2018
Submitted by: A_baldini
Specimen type: Photograph
Observation notes: Time: 9:30 a.m. Temperature: ~Low to mid 60’s. Wind Speed: ~5 mph. Sky: Mostly hazy (thin layer of clouds). Notes: I caught this marble above Dixon Reservoir, on a steep slope between the parking lot and the road. The most prominent vegetation was some large lilac bushes nearby, probably a nectar source. Before I was able to access BAMONA back home, I couldn’t decide if it was a Large or Olympia Marble, but I’m now set on Olympia because of the sparser veining. On the drive home, I saw an enormous yellow butterfly (Papilio multicaudata, possibly rutulus), which I thought was strange because their flight season usually doesn’t begin until late May.

Coordinator notes: You were correct deciding this was the Olympia Marble. I use to catch them commonly up around Horsetooth on the hillsides also (nearly 45 years ago). There are some really good hills and ravines on the west side (one road goes up into a housing area....something Canyon Estates I think if the name isn't changed or is now gated). Got lots of good things there and on the hilltops above. Mike
