We’d made promises in the recent past that fell flat. With that in mind, when the Greater Lovell Land Trust’s Nature Explorers, a homeschool group led by Docent Juli, gathered this morning, she was smart and stuck to the life cycles of potential sightings like frogs rather than possibilities.
The group that gathered was large–24 in all with a mix of moms and their children.
Of course, being kids, they were immediately attracted to the water below the mill site at Heald Pond. But after letting them explore for a few minutes, a light whistle pulled them all together again.
At the nearby vernal pool, everyone quickly learned what larval mosquitoes looked like as they watched them somersault through the water column. A few complaints were expressed about future bites, but that was redirected to the fact that mosquitoes feed birds and dragonflies, and in their larval form, other aquatic insects.
Pond dipping became the morning habit and at first, it was only the mosquito larvae that made it into the containers.
But, that led to a quick lesson on the biting insects’ life cycle–one of many teachable moments that snuck into the morning fun.
Oh yes, those larval mosquitoes also feed amphibians and thanks to Juli’s son Aidan for finding a large Green Frog. Notice the ear disc, aka tympanum, that is located behind its eye. Given its size as being bigger than the eye, this was a male. And notice the dorsal lateral ridge or fold that extends from behind the eye down the side of its back (there’s one on either side)–that’s a clue that this is a Green Frog and not a Bull Frog, for the latter’s ridge circles around the tympanum.
As the morning went on, it turned out that today was Aidan’s day to shine for he was also the first to find a Fairy Shrimp.
A what? Yes, a Fairy Shrimp. Do you see that delicate orangish body in the middle of the tray? It’s a mini crustacean that lives only in vernal pools.
The kids all got caught up in the thrill of such a find and within minutes became pros at recognizing them.
And so the dipping continued.
Moms also got caught up in the dipping experience.
And they also found cool stuff, like Kim’s Fishfly. We kept expecting it to eat the mosquito larvae, but it seemed that they preferred to nudge it in a way we didn’t understand.
While Kim focused on her new friend, the kids were also making new friends, testing their balance, getting rather wet and muddy, and having a blast as they sought more Fairy Shrimp.
Their pan began to fill up with one, two, three, four, five and even a few more.
And then other species were discovered, including aquatic beetles and a Phantom Midge.
We’d come in hopes of at least finding Wood Frog and Spotted Salamander egg masses, which the kids quickly recognized. By the time we were ready to leave a few hours later, some of the boys had discovered the best way to spot the masses was from the crow’s nest.
But in the end, our most significant find was the Fairy Shrimp. You see, on a public walk a couple of weeks ago, when we’d promised folks such a sighting, we came up short. But today . . . they made their presence known. And with the find of just one Fairy Shrimp, the vernal pool became a significant one as recognized by the State of Maine.
A hearty thanks to Juli for leading and the moms and their kids for attending. It was such a joy to watch everyone interacting and engaging. I only wish I could have been a Fishfly on the wall at suppertime as they shared their finds of the day with other family members.
