We saw this up the old Fish Creek road (in the Clackamas area). They seemed to all be coming out of rotting alders We saw quite a few instances of them. I don't ever recall seeing them before, but since they require a very specific set of circumstances, I can understand why.
The purpose of this forum is to help people identify things they've seen while out hiking: wildflowers, trees, birds, insects, small animals, animal tracks, even geographical features like buttes or streams
Life is not a journey to the grave with the intention to arrive safely in a pretty and well-preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming: WOW-What a ride!
