Submitted by: harleyrhoads
Specimen type: Photograph
Observation notes: Sitting under my old cottonwood tree. Acted like we weren't even there. Impressive how the male makes it seem as if they are one and very large as if too scare away predators. It has been a super wet year here in Moab, Utah. The last week has been hit and dry with cool nights 101° during the day down to 69° last night.
