Friday 5: Winter Invertebrates

Last weekend I led a public program for work that focused on how people can use nature photos to help scientists by submitting them to a variety of citizen science projects.  I really love doing this program as the people who sign up tend to be REALLY excited about documenting the natural world with their cameras, just like me.  I get people with all sorts of cameras too – really cruddy cell phone cameras all the way up to pro-level photo gear – but somehow the group dynamic just works.  We do a bit of introductory stuff in the classroom and then spend a lot of time practicing our photography and learning about the flora and fauna of North Carolina.  It is a ton of fun!

Last weekend, the morning started off very foggy.  It was supposed to clear off in the afternoon and become a magnificent day, but it was still dark and gloomy only an hour before the program.  Then, all of a sudden, the fog was gone!  The sun came out.  It was 75 degrees!  Toward the end of the program, I was roasting and started stripping layers off and ended up in a tee-shirt.  It was great.  And, not surprisingly, we found several invertebrates active, taking advantage of the most beautifully perfect winter day I could imagine.  Here are some of the spineless creatures we saw!

Ants.  LOTS of ants.

My most recent group of photographers got really into flipping logs!  We found all sorts of things lurking under them, including this colony of ants.  We have a lot of fire ants in the south, so it was nice to flip up a log, see several hundred ants underneath, and NOT have them come after you, stingers a blazin’, for daring to disturb their nest.  These ants seemed pretty docile as close to a dozen photographers snapped shots of them and the guy holding the log didn’t get stung once.  This was one of my better ant experiences actually.  I tend to have mostly bad ant experiences of the stingy, bitey kind…

Snails

There’s something about snails that I love.  I think it’s the eye stalks.  In fact, I’m sure that it’s the eye stalks.  Those things make snails look adorable.  Of course, snails are also important herbivores and detritivores, so they play an important role in the environment that shouldn’t be overlooked.  And, because I can’t think of snails without also thinking about this, I encourage you to watch the snail animated short that Miniscule did a few years back.  You WILL fall absolutely in love with snails after watching it!

Millipedes

Millipedes

Nearly every log I’ve flipped in North Carolina so far has housed at least one millipede under it.  This particular log had a lot of them.  All those little white things…  Those are all millipedes, and there were probably about 100 of them under this one log in a big mass.  Someone’s been getting busy procreating under this log.  :)

Pillbug

Sowbug

Sowbug

Did you know these guys (pill bugs, sow bugs, rolly polys, etc) are actually little land crustaceans?  I’ve always wondered whether they taste like the crustaceans people like to eat, such as lobsters and crabs.  (Don’t suppose any of you out there have tasted one so you can tell me what they taste like?  Because I don’t eat crustaceans.)  Like the millipedes in the previous photo, pillbugs are decomposers and are very important in forested areas like the one where I found this one.  There, they turn dead trees into soils so more trees can grow so more pillbugs can turn them into soil so…

And finally, I present this beetle:

Darkling Beetle

It never fails!  I tell a group of people that, because it’s been rather chilly the last few weeks, we’re unlikely to find many insects out and about.  Then we started flipping logs and found several insects and insect relatives.  One woman in the group was particularly interested in learning how to take better insect photos and was thus highly motivated to find as many as she could.  This was the largest insect we saw active while we were all together, a darkling beetle that was about an inch long.  It sat there and posed for quite some time as several photographers stuck their cameras right in its face to snap some shots of it.  It was even kind enough to sit on a lovely backdrop of dead leaves!  I thought it was rather beautiful, and I was glad we got to see at least one insect that wasn’t hidden under a log.

Turns out there were other things out as well, but I got wrapped up in helping people identify plants and birds and insects and answering questions about Prairie Ridge and I had to stop taking photos myself.  Sigh…  That’s what happens when you’re leading a group program though!  And it was worth it.  It was a gorgeous day and the group I spent it with a lot of fun, so it was a great day overall!

Not sure how many insects I’ll see for the next few weeks.  It finally snowed last night, so they might stay out of sight for a while as they wait out the cold.  Still, I hope I can bring more winter insects to you all soon!

    • Sorry, can’t help you with snail guides as I’ve never tried to ID any snails out of water. If you happen to come across a good source though, I’d love to know about it! Someday I’ll ID all my snails…

  1. “A Guide for Terrestrial Gastropod Identification” from a 2008 American Malacological Society workshop is a free pdf. It’s mosty an overview of diversity, with a lot of references, along with guides to anatomy and collection.

    I covet introducing Pacific Sideband (Monadenia fidelis) snails into my native plant garden, which I hope is now grown up enough to support them. They’re native here, but are now rare or gone from the city. But first I want to learn to keep them in a terrarium–they can live 6 years or more, so should make good pets if they can’t make it in the yard. So when I almost stepped on an adult invasive european Brown Garden Snail, Cornu aspersa, last summer, I kidnapped it and held it prisoner for a few months as practice. I had no idea how much cleaning it would take! I’m more used to the tiny garlic snails who do very well with a pint or so of soil plus duff and no care whatever. I’ll have to find room for a 15-25 gallon terrarium which can hold enough soil critters to help out with the cleanup before I go hunting for my sidebands.

    • Thank you for sending the link to the reference! I look forward to perusing it. Also, good luck with your snail hunt and care! I used to have several aquatic snails, but I found that they were so difficult to keep clean that it wasn’t worth it and gave them to someone else who wanted them. Sounds like your land snails might be similar, but I hope they do well with you!

    • All the little garden snails I’ve seen here have black bodies. I had no idea that it might not be common, but then I moved here from the desert. We didn’t get a whole lot of land snails in that very arid climate!

  2. A just post for the winter up north, Dragonfly Woman! I have also observed spiders in the family Tetragnathidae and Araneidae clinging onto dry inflorescence in the freezing winter of south-eastern Canada. It will be interesting to learn about these from your winter trails!

  3. I was out with an ant researcher one day and we were struck by how carefully he replaced all the pieces of rotten wood as he found them – their homes are so delicate. I have always been more careful since, exposing the underworld!
