Photos of the Week – April 8, 2025

Across much of the Midwest and Great Plains of North America, the blooming of eastern pasqueflower is a pleasing indicator that a new growing season has begun. For photographers like me, it also helps break a long fast from showy wildflowers that typically runs from late October through early April each year.

Pasqueflower at The Nature Conservancy’s Niobrara Valley Preserve this week.

Pasqueflower isn’t always the first plant to bloom in a prairie, but it’s right there, and there aren’t many other early spring blossoms with more curb appeal. Actually, saying “it’s right there” is misleading because pasqueflower is not actually present in most of Nebraska’s prairies. Its range extends across the state (or the northern 2/3 of the state, at least) but it’s found very sporadically within that range.

Most of the prairies I know best don’t have pasqueflower, but there’s a really nice population at the Niobrara Valley Preserve. Since first discovering it there nine or ten years ago, I’ve tried hard to find an excuse to travel to NVP each April and then find another excuse to climb the ridge to check on the flowers. This year, the excuse was that the Hubbard Fellows and I were asked to drive up to NVP to help with some prescribed fires. I was happy to oblige!

Because it’s one of the first blossoms available, pasqueflower attracts a lot of invertebrates looking for a meal. A rich diversity of flies visit pasqueflowers at the Niobrara Valley Preserve, along with some of the earliest of the native bees. This year, I didn’t spend a lot of time trying to photograph those little pollinators, but I did manage to capture a shot of one tiny fly before it flew off.

Flies and bees are great, but the pasqueflower-related insect I really look forward to each year is the oil beetle (Meloe sp.). The very first time I photographed pasqueflower at the Niobrara Valley Preserve, I spotted some of these big bulbous beetles crawling around. I was immediately intrigued, and later found out what they were. That led to some investigation into what was known about their lives and that led to one of my favorite insect ecology stories ever.

As a result, I was excited when Noelle (one of our two Hubbard Fellows this year) found a little cluster of oil beetles when we visited the pasqueflowers this week. I’d told the Fellows about the little creatures as we got close to the flower patch and had asked them to keep an eye out for them. I then proceeded to walk right past the group of beetles Noelle spotted after immediately after I passed them. So much for my reputation as someone with a good eye for finding small creatures.

I’ve posted pasqueflower and/or oil beetle photos quite a few times on this blog now. In fact, probably six times, since that’s the number of times I’ve had a successful trip to NVP during the pasqueflower blooming season since I first discovered them. I don’t always find oil beetles on the flowers, but I find them more often than I don’t. It’s also the only time and place I’ve ever seen oil beetles.

Each year, I think I say the same thing, which is that I’ve found no evidence that oil beetles focus particularly on pasqueflowers as a food source, at least relative to other options. So why don’t I see them elsewhere? Despite this year’s failure, I really am pretty good at spotting insects, and oil beetles are pretty large and obvious. It’s odd that I’ve never seen oil beetles in other prairies or on other plant species.

The fellows and I enjoyed some quality time with the flowers and beetles on Tuesday morning, before heading back south toward home. Much of that time was spent with heads close to flowers, watching the slow, methodical munching of petals. It was peacefully mesmerizing.

In fact, here’s a short video to show you what I mean. (If the video doesn’t work for you, click on the title of this post to open it online and make the link active.)

If you’re tired of seeing pasqueflower and oil beetle photos here each spring, I guess I apologize for putting you through that particular trauma. On the other hand, no one is forcing you to be here.

For those of you who haven’t left, here are two more!

I’d love to hear if other people see oil beetles on pasqueflower as predictably as I do. I think I’ve only heard from one other person who has seen that. I’ve found no references to an oil beetle/pasqueflower interaction online, but that doesn’t mean it doesn’t exist. Help!

If you live near a pasqueflower population, I hope you get a chance to see them this spring. Even without the oil beetles, they’re sure a great way to kick off the spring.

Celebrating Seeds

I’ve been seeing a lot of brand new plants germinating from seeds during the last couple weeks. Looking at all those cotyledons (first leaves) poking out of the ground makes me reflect on the massive amount of good fortune it takes for any seed to actually turn into a new prairie plant.

Prairie dandelion seeds (Nothocalais cuspidata).

Seed production is a high risk, high reward strategy for plants, and even that’s a huge understatement. It takes a tremendous amount of energy for a plant to produce a flower – especially if you’re trying to make one that’s attractive to an animal pollinator. There’s all the colorful petals or other structures, nectar (in many cases), and, of course the pollen itself. After pollination, even more energy can go into loading up the developing seeds with the nutrition and energy needed to give the embedded embryo a chance of success.

Once the seeds are released from the plant, they often travel away from their parent – at least far enough that they aren’t trying to grow directly beneath them. The varied tactics used by plants to disperse their seeds is a huge, fascinating topic, which I’ve written about before. Regardless of whether a seed travels by wind, water, attached to the fur or feathers of an animal, or by being eaten and then pooped out, there are myriad dangers along the way.

Prairie violet (Viola pedatifida) seeds can travel in two ways. First, they are ballistically launched into the air as their pods dry and constrict. Second, many are picked up and carried home by ants because of the little fatty packet of nutrition (elaiosomes) violet seeds have attached to themselves for that very purpose.

Seeds packed with nutrients to feed their embryo are also a great food source for many other organisms. Countless vertebrate and invertebrate animals seek out and eat seeds, especially during the dormant season when most other food sources are scarce. Fungi and lots of microorganisms can also destroy and consume seeds.

If, by some minor miracle, a seed survives its short or long journey intact, it may still be a long way from ultimate success. For most plants, germination only happens if a seed is in good contact with soil. Think for a moment about the world a seed is launched into and how many obstacles there are between that seed and the soil!

When you walk through most prairies, if you look straight down, you’re not seeing a lot of bare soil. Instead, there are a lot of living and dead plant parts (leave, stems, etc.) between your feet and the ground. A recently-burned prairie, of course, has lots of bare ground. That’s a great opportunity, but only for any seeds who weren’t consumed by the fire itself.

Most seeds land on something besides soil. Often, that’s the end of their journey and they sit there until they die (e.g., the embryo runs out of stored food) or they’re found and consumed by another organism. If they’re lucky, they might get dislodged from their original landing spot by wind or rain, for example, and slip downward toward the soil.

Let’s say a seed has led a lucky life and manages to reach soil. It might even get pushed into that soil slightly by rain or a passing animal’s foot. Hooray! Now it can grow and reward its parent’s huge investment.

Well, maybe.

Most seeds need water to germinate. During drought periods, a seed might sit in the dusty earth for weeks, months, or years, waiting for sufficient moisture to help break its seed coat open. As it sits there, it’s vulnerable to any passing animal, fungal hyphae, or tiny microorganism looking for a meal. Plus, as we discussed earlier, the embryo might simply run out of food.

Even if rain or snow provides sufficient moisture for germination, some prairie seeds also need a certain amount of sunlight to trigger germination. (This is why it’s important not to plant prairie seeds like you plant pumpkin or green bean seeds. Just scattering them on top of the ground is often best.) If a seed that requires light lands on bare soil that happens to be in the shade of other plants, it might still be stuck in limbo.

Illinois bundleflower seeds have such a strong seed coat they can survive a trip through the digestive system of an animal. That’s great for the seed, but doesn’t provide any reward for the poor hungry animal!

As a result of all the challenges they face, only a tiny percentage of seeds released into the world by their parents actually end up germinating. Those that do have a chance to perpetuate the family line. However, simply reaching the germination stage isn’t the end of the race.

A tiny seedling still has to compete with any nearby plants for food, water, and sunlight. Only a small minority of prairie plant seedlings make it to maturity and create their own flowers and seeds. They either wither and die in the face of more competitive neighbors or get eaten by herbivores looking for fresh new growth to nibble on.

Despite the odds, of course, some seeds do manage to germinate and then become parents themselves. We’ve got abundant evidence of those successes all around us. It’s easy, though, to take those winners for granted. Spare a thought for all those who didn’t make it!I’m cheering on all the little germinating plants in the prairie right now. They’ve already survived a ton of obstacles, but they still have a lot to overcome.

I often wish seeds good luck when I see them, too (usually silently, especially if other people are around). While most seeds fail to become plants, each one of them plays a vital role in the prairie ecosystem. Animals and other organisms have to eat, after all, and seeds help keep lots of other community members alive.

Apart from everything else, seeds and the structures that help carry them into the world are simply beautiful. I’m incredibly appreciative of the diversity and aesthetic elegance of prairie seeds and I’ve spent a lot of joyful hours photographing them. I just try not to dwell too much on their individual survival chances…
