POTD: A Use for Pond Scum

A Use for Pond Scum
Bozeman, Montana

We’ve been fighting pond scum in one of our ponds for several years now. It turns out that not everyone thinks it useless and unsightly. I thought this frog was just sunning himself on this patch of scum but it turns out he was just on the job. A bug landed a few inches in front of him and, zap, lunch was served. Good things come to those who wait.
