Coordinator notes: You have taken numerous photos of Petrophila moths, and they have been most instructive. Most have been difficult to place comfortably into species due to variation within species and the paucity of moth data from Wyoming. This photo fits comfortably into P. avernalis. Thank you for patiently submitting many photos. Your photos are typically high quality it is just the limited documentation of the Wyoming moth fauna that causes many to end up not being identified. Thank you again for your persistence.
