On April 10, the ice had started to melt on the little vernal pool behind our house. And I got excited.

Suddenly it was time to start paying attention on a daily basis.

Within a few days, following a long winter of being frozen under the leaf litter, male Wood Frogs arrived at the pool. I heard their “Wruck, wruck” quacks as I approached and recognized that love was in the air. But the moment I stepped to the edge, all went silent and the frogs dove to the bottom. Standing as still as possible, I watched as they slowly began to resurface.

A few days later, it was in the pool. Love that is. The females had arrived, their abdomens swollen with eggs. And tada, the Wood Frogs were in business. A male, and it could be more than one, jockeyed for a chance to grasp a female around her waist in a long embrace and fertilized her eggs externally as she laid them.

A week or so later, and all was quiet again on the vernal pool front, for momma and papa had exited the water and returned to the forest floor in search of food, and the nursery was left to develop on its own in the form of a lumpy mass of eggs with a single embryo elongating within each.

About a week later, Spotted Salamanders crossed the road with a little help from some human friends, and they (the salamanders) also sought out their natal vernal pools in which to breed.

To do this, the salamanders performed a dance in which he stimulated her rather than participate in amplexus like the frogs. Then he deposited little packets of spermatophores consisting of mucus and a sperm capsule, and enticed her to crawl over such. According to Mary Holland’s blog, Naturally Curious, the female “positions her vent, or cloaca, so as to allow the lips of her cloaca to detach the sperm capsule . . . she collects his sperm into her body and internal fertilization takes place.”

If you look closely at the two plugs attached to the leaf, you’ll notice that the one to the right still had a sperm capsule attached.

I always think of them as little bundles of cauliflower.

And another tada, the eggs were laid and began to swell up, surrounded as they were by a gelatinous mass (and this one momentarily lifted into a container at the surface of the water for educational purposes), and the parents returned to the their mole-like life below the leaf litter, to be spotted rarely until next year’s Big Night.

In yet a different wetland locale, I found Painted Turtles basking together on a log. Being ectothermic, or cold-blooded, their body temperature depends upon the environment and in the spring they need the sun’s rays to warm them up to an internal temperature of 63˚ – 73˚.

Because the spot where I saw the turtles was not a vernal pool, but rather a bog, I didn’t spy any Wood Frog or Spotted Salamander egg masses, but there were tadpoles of another type upon which to dine, like this Bullfrog, which takes two years to mature.

And leeches. A plethora of leeches floated past the rock upon which I stood. Not all leeches suck human blood. Many prefer that of amphibians and reptiles.

Visiting several other vernal pools, Predacious Diving Beetles soon made themselves known in several forms, from this, the larva, aka Water Tiger, with its strong mandibles, ready to grasp prey at any second . . .

to an adult.

The body of a Predacious Diving Beetle is oval with oar-shaped hind legs that feature fringed hairs to increase stroke power. So here’s a thing I learned last week and now try to pay attention to: when swimming, Predacious Diving Beetles kick both hind legs simultaneously, whereas Water Scavenger Beetles, which look similar, kick their hind legs alternately.

Oh, and do you see the Mosquitoes wriggling behind the beetle?

Speaking of behind, look at the beetle’s behind–it’s an air bubble. They trap oxygen-filled air between their wings and body, prolonging their time under water. and thus can stay under for long periods of time, returning to the surface when it runs out.

So back to the Mosquitoes. Meet the third stage in their life cycle (egg, larva, pupa) known as a tumbler. Tumblers lack mouth parts because they don’t eat while undergoing the magical transformation into an adult. Spying this means that very soon biting female Black Flies and Mosquitoes will be part of the landscape. They’ll annoy us, but we need to remember that they are food for others, like tadpoles and birds and dragonflies.

As for the biting insects, I’ll try to practice mind over matter because I can’t resist the opportunity to learn more and be present as I hone my focus above and below the water’s surface.
