Spring Ephemeral Series #1

Towards the end of May (roughly) is when all the spring ephemerals in the woods flower each year. It is an impressive display, but it is fairly brief. (You could say it lives up to the name ephemeral, I suppose.) I wanted to make a post about it, but with multiple years worth of photos, it was turning out fairly long, so I decided to make it a little series instead, and just spotlight one or two of the different species I’ve observed per post.

Wild Geranium

Wild geraniums are the most numerous of the spring ephemerals in our woods, which is part of their charm; it would be hard not to be impressed by the way they quite literally carpet large areas of the woods. I’ve tried many times over the years to capture a good sense of this in my photos, but although I’ve made some improvements and gotten some good photos, I’ve come to the conclusion that nothing will quite compare to seeing it in person. But that doesn’t stop me from trying to do the best I can with it.

Like quite a few native wildflowers, wild geraniums have at least one specialist pollinator: the cranesbill miner bee (cranesbill is another name for the wild geranium). Being specialist pollinators means that these bees will only use wild geranium pollen for feeding their offspring, though the adults may visit other flowers for nectar.

This is probably a cranesbill miner bee (I am at least certain that this is some type of miner bee), but miner bees can be very difficult to identify to the species.
Of course wild geraniums also provide nectar and pollen to a variety of other non-specialized pollinators too, like this agapostemon (sweat) bee.

This certainly won’t be the last you see of the wild geraniums in this series; they show up alongside the other ephemerals in many of their photos, too.

Ice Formations in the Mountains

Although it mostly wasn’t super cold while I was in New Mexico, there were still some interesting ice formations to be found in the mountains, particularly around streams. This was partly because it was colder the higher in the mountains you got, but also because the temperature differences between day and night were more extreme there.

This is what happens when a waterfall freezes (partially, anyway). Though you can’t really see it in a still photo, there was water flowing a bit behind this wall of ice.
This is the center of the waterfall in the previous photo. It was still flowing through the center, but there was a chunk of ice in the middle of the flowing part that looked a bit like an explosion of ice, which was causing the liquid water to splash around pretty wildly. It’s kind of hard to tell in this photo what water is frozen and what water is just in active motion.
This one’s a close up of the wall of ice in the first photo.
I think this picture has interesting contrast with the smooth, rounded ice and frothy bubbles.
More ice and bubbles.
These icicle-like formations were on the underside of a log over a churned up bit of river. I’m guessing they formed from the spray of the river running to the bottom of the log and freezing before they could drip back down.
I found these tiny ice formations on twigs after climbing up the same rock where I also found some of the lichens in my lichen post. I was pretty excited to find these, since I haven’t seen any ice formations quite like this at home. When I found these, and for quite a while afterwards, I wondered what the conditions were that made it possible for these to form. Recently, I stumbled across something that may be an explanation.
Certain ice formations occur due to specific interactions with plants or fungi. I recently learned that there are a few different plant species that create ice formations when their sap freezes and bursts out of the sides of the stem, which is actually sort of what appears to be happening in this picture in particular… But on the other hand I wasn’t able to find information about any of these plants being in New Mexico. It would help if I could see this spot during the summer.
