My interest in tadpoles development and metamorphosis has been growing recently since my tadpoles have grown small hind legs. they are both bullfrog tadpoles that I found at Nobscot scout reservation. there is a vernal pool there. I found both my newts, my moss and my tadpoles there. I see collecting there as rescuing them from being dried up later in the year. the vernal pool rises in march and evaporates completely in September. Below is a photo i took of it while it was completely dried up.
in the above image you can see rocks and logs scattered in the middle of the pool. lifting them up results in finding newts, salamanders, large spiders and aquatic insect carcasses. in the spring, when it is filled, it is full of aquatic newts, Aquatic insects, frogs, tadpoles, water snakes, caddisfly larva, dragonflies, and many other really cool creatures. i rescued my 2 tadpoles from a mud puddle while the pond was almost empty. they were skinny, weak and bruised. 2 months later, they are going through metamorphosis, fat and healthy. they also have the entire algae filled 30 gallon aquarium to themselves. i have been exited seeing there changes into froglets.
I also find them to be really cool, yet easy pets. they are not very messy eaters and require minimal care. all they need is an aquarium with algae growth. sometimes, when i stick my arm into my aquarium to rearrange or add something, they will graze on my arm for unknown reasons. maybe they think something about the texture of skin resembles algae.

Last night at about 8:00 pm, I checked on my Eight Eastern Newts that were in a container in the garage to see if they had eaten there Blood worms already. (Blood Worms is a term that means Midge Larva). there were still some remaining. my eye darted over to seeing my largest male courting a female. the male had wrapped his legs around the females throat. (this is called amplexus) about every ten seconds, the male would wag his tail like a snake. his head was also turned around backwards so that he could watch her reaction to his courtship display. he appeared to have 2 types of tail wagging. one where he rubs his own back with his tail, and one where he waves his tail at her Cloaca (genitals). the female was motionless, as if she was in a trance. they continued this for hours until after i had gone up to bed. the male would have dropped his spermatophore (sac of sperm), hoping the female was wooed enough to want to pick it up. i do not know if she did or not but i would assume she would because the male that she mated was was very large, and very healthy. the male had kept alternating the 2 motions. i think that maybe he is gathering a pheromone on his back and then pushing it towards her. all part of the courtship process. the image below shows them engaging in amplexus.
as stated in my nature journal, my winter goal is to get my adult newts to produce offspring. catching them in amplexus is reassuring in the sense that it means that they are trying to reproduce.

Last weekend, I was in Cornish, Maine for a relative's burial. after some time, i realized i was bored, and decided to fidget with acorns, as i was rotating one of the acorns, I noticed a hole about 3 millimeters in diameter.
i knew from past experience what was living inside. i dropped it on the ground and stomped as hard as i could on it.
The ground was cold and hard and the acorn cracked. I then pried it open. normally, acorns are filled with a white-ish, hard, living interior, that is the seed, however, this acorn was filled with a brown, fiber-loaded paste. Feces. I now knew what was inside for sure, I dug with my thumb through the disgusting material and found what i was looking for. an Acorn Weevil Larva. This was a very fat, wrinkly white parasitic caterpillar. Parasitic to the acorn. Not people. Just wanted to clear that up. its head was orange and shiny. I was not able to photograph the larva itself, because the above pictures were from a different time, when there were no larva still inside. just shit.
Acorn Weevil adults tunnel into, and then lay their eggs in an acorn, then, the acorn will seal itself, protecting the larva that will then eat there way out, replacing seed with shit. they then metamorphisize into small brown beetles, which climb out, restarting the life cycle. the orange fluffy material in the picture above is the Testa (Hairs in the seed to insulate and protect the embryo from environmental conditions.)
the Acorn Weevil is native to Europe and, my guess is it came over through acorns, that fell from an oak tree in Europe, ended up in a ship, and then emerged after arriving in america.
whenever you see an acorn with a round hole in it's side, you now know what lives inside.
