Since about the beginning of this week when the weather suddenly warmed up frogs have been broadcasting their loud cacophonies. A certain species lives in a flooded area near a creek not too far from my house. I have recorded their calls and got a possible identification: spring peepers (Pseudacris crucifer). For confirmation, I figured I needed their pictures. So late this afternoon I took my camera, put on my rubber boots and entered the swamp.
Frogs were everywhere; I knew that because they were deafening me with their calls. For about 40 minutes I searched for them to no avail; not one made itself visible to me. They are supposed to be small, only about 2 to 3 cm long. So I was looking very carefully. But instead of tiny frogs, I kept picking up even tinier snails from among the plant litter in the water. First, there was this succineid, probably a juvenile Oxyloma retusum, a land snail of wet places. Compare it to the size of my thumb.
Then there was this aquatic species. Let my finger be a scale for its length.
It didn't have an operculum. So it was a pulmonate, possibly a Fossaria species. It was actually hard to see it when it was crawling on the debris matching the color of its shell.
All the while the frogs kept up with their shrill. But my eyes, obviously programmed to see snails, could not see them.
I will continue my quest tomorrow afternoon.
