Sheep Creek in the Cascades of Oregon

Here’s a lovely creek in the Cascades of Oregon.   This part of Sheep Creek is at 795m elevation.  It has a rich bembidiine fauna living in the gravel patches along the shoreline.  In addition to two species of Lionepha (L. casta and L. sequoiae), there are six species of Bembidion.  Five of the species belonging to the Plataphus Complex of Bembidion: B. turbatum, B. curtulatum, B. haruspex, B. nigrocoeruleum, and an undescribed species related to B. sierricolaB. iridescens, a widespread species in the Pacific Northwest, also lives here.
