Photo of the Week – June 29, 2017

Monday night, I spent some time exploring the east bison pasture at the Niobrara Valley Preserve as the sun was going down.  The bison have been concentrating their grazing on the east end of the pasture that was burned in March.  Within that patch, most of the grasses have been grazed, along with the wildflowers they like best.  The sky was pretty spectacular, so I spent time photographing the vibrant green landscape and the bright wispy clouds above it.  When the sun was nearly down, however, I noticed the light illuminating patches of woolly plantain (Plantago patagonica), an annual plant that had just finished its flowering season.  I dropped down to the ground and photographed the backlit plants until the sun finally disappeared.

I ended up with two favorite images from those few minutes.  I like them both for different reasons, so I decided to share them both.

Woolly plantain is not a plant most people would call regal or beautiful, though it certainly has its charm.  Because it’s often overlooked, I like that these photos feature it so prominently.  Woolly plantain is a space-filler, a plant that can’t handle competition.  It grows and flowers only when other plants are weakened enough that it can find spaces between them.  A burned patch of sandy prairie grazed by bison creates perfect habitat for woolly plantain, and these photos celebrate the plantain, the prairie, and all of the processes that link them all together.

…Plus, it was pretty dang cool to be lying on my stomach, watching the sun go down over a huge prairie landscape while a big herd of bison grazed in the distance…

It’s a WHAT??

We are doing an intensive week of data collection at the Niobrara Valley Preserve this week.  Yesterday, while I was leaning over to look at something, an insect landed on my clipboard.  It looked like this (photographed later):

“Interesting,” I thought, “that’s an odd-looking paper wasp…”

Then I peered more closely at it and immediately decided I needed to capture it so I could take it back to the cabin and photograph it.  Unfortunately, I didn’t have any bags or containers to put it in.  All I had was my aluminum clipboard, which has a skinny compartment for storing extra data sheets.  I very carefully nudged the insect inside and carried it back to the truck, where I transferred it to a nice roomy ziplock bag.  When we got back to the cabin, I set the creature on a small sunflower plant and took about 230 (not kidding) photos of it.  Here’s a nice one from the side:

Basically, I was looking at a wasp-looking insect with front legs like a praying mantis.  I’m no entomologist, but I’d never heard of a wasp-mimic praying mantis in Nebraska, so I was confused.  Also, mantids don’t have antennae, and this little critter had two of them, which it waved constantly and rapidly.  What in the world…??

Fortunately, the modern naturalist has Google to fall back on, and once I got on the internet, it didn’t take long to figure out what this was.  As it happens, it’s neither a wasp or a mantid.  It’s actually a wasp mantidfly (Climaciella brunnea) which, by the way, is also not a fly!  I’d heard of mantidflies, but I don’t think I’ve ever seen one in our prairies.  They are fairly closely related to lacewings, and slightly more distantly related to antlions.  Wasp mantidflies can be found throughout much of North America, but either they’re not super abundant on our prairies or I’ve fallen for their mimicry an awful lot.

As I photographed it, the mantidfly didn’t seem at all concerned with me, and started hunting ants – including this one, which it struck at but missed.

One of the constant themes of this blog is my sense of wonder at the kinds of discoveries I get to make just by paying close attention to the natural world around. me.  Mantidflies are certainly no mystery to entomologists, and I’m sure numerous readers saw the first picture and knew immediately what it was.  However, the wasp mantidfly was new to me, and has quickly added itself to the long list of amazing organisms I’ve gotten to know and admire.  Perhaps the greatest joy of being an ecologist/photographer is that I keep finding new species to add to my list on a regular basis, despite having been a professional ecologist for 20 years and a nature enthusiast for my whole life.

What a tremendous world we live in!
