The formula of nature: Rain + pond + warm summer nights = leopard frog eggs!!
A closer peek: In 3 days we should see little tadpoles in this tight little cluster. The eggs are surrounded by a gelatinous sac of clear goo to protect the eggs and young tadpoles and keep them clustered together.
Beautiful and amazing! I would definitely have a macro lens zeroed in on those egg clusters! That is definitely a Rio Grande leopard frog.
