Pacific Tree Frogs

We are fortunate to have a couple of wetland ponds between our house and the river. The provide habitat to Pacific Tree Frogs which we hear in the spring. The other evening we spotted one on the wall of our house. Not too unusual a place until you realize that he is positioned near the black light which is used to attract moths. Was he being opportunistic? We didn't notice him catching any moths while we observed him. He was gone by the morning. I have noticed Black-capped Chickadees come searching for dead moths that get trapped in spider webs. The black light is actually an ultra violet light or 'party' light that makes your white clothes very bright at night.
