Sighting Record 1205207

Observation Notes: 
Warm, sunny afternoon. First noticed butterfly fluttering from leaf to leaf in a shaded patch of stinging nettles along a creek. I waited a few moments and the butterfly landed at my feet to bask in a spot of sunshine on a mud step that allows access to the creek. After a short time basking it returned to fluttering through the nettle patch. Due to lighting and angle of view I could not tell if it was ovipositing.

Specimen Type:

Organism Type: 
butterfly

Sighting Record 1203663

Observation Notes: 
Out of expected range. Phyciodes mylitta flying in same area at same time so I could compare size. This butterfly is 2 to 3 times larger than Phyciodes mylitta in same area. To give an idea of scale/size of this butterfly: plant it is nectaring on is Mahonia Aquifolium. Flower clusters are described as 2 to 3 inches long. Leaves are made up of leaflets that are 1 to 2.5 inches long. If this is actually a Pale Cresent I need to let the folks at the wildlife refuge know. Plenty of small Canadian thistle plants around.
Region:

Location Notes: 
Take the main, year-round, trail from the parking lot into the refuge. As you pass the picnic tables on your right, start looking for butterflies in the weeds to your left until you get to the sharp bend in the trail. Also found Silvery Blue and Mylitta Crescents along this stretch
