Spider in the Hole

Early last November, the Carolina Wolf Spider residing at the edge of one of my vegetable garden beds, sealed off the entrance to her burrow in preparation for surviving the cold winter season.  The earthen seal remained undisturbed through the winter.  On March 16 of this year, the seal was removed and the burrow reopened.

Heavy snow flattened Butterflyweed stalks and effectively erased signs of the burrow entrance.  Had I not placed a white marker stone a few inches from the burrow, I would have had a hard time deciding just where I should be watching for the reappearance of the burrow.

On March 21 I caught my first glimpse of the spider.  I was happy to see that she had survived the winter with no noticeable negative effects.  With no nearby standing cover, it’s hard to get close to the burrow without scaring the spider back inside.  The spider is just about dead center in this shot.

Fortunately, the spider was quick to reemerge from its burrow, so I had plenty of photo opportunities. 

This spider is a female who would have been hatched in the summer of 2013.  She attained her adult size last summer and should have mated sometime in the fall.  That means she should be producing eggs this spring that will hatch in early summer.  I’ll be keeping a close eye on her in hopes of witnessing some of the young leaving the burrow later on.

Vegetable Garden Distractions

I’ve been interested in vegetable gardening for most of my life and have had some type of garden every year since I was eight years old.  Maintaining a vegetable garden is an activity that my wife says makes me appear more normal in the eyes of the general public.  It gives me a second topic besides the weather of which I have an interest and which I might discuss with others while creating idle conversation at social events.  I’ve learned that most people can only stand a few minutes of weather talk and generally have no interest in my thoughts about managing land for native ecosystems.  Talking about gardening gives me something to do besides reading a book or standing alone glaring at anyone who comes near.  This pleases my wife and gives the illusion that I’m having a good time.


My garden is located in the lower portion of a field drain where eroded soil was trapped behind an elevated farm lane.  This was the only place I could find with soil deep enough to securely anchor fence posts.  People sometimes question why I carved my garden out of a nice prairie field.  In this situation there was no prairie when I created the garden.  At that time, the field was all oat stubble, remnants of the last grain crop to be grown there.  The garden was long established by the time the prairie came in.


The garden is maintained in raised beds.  Through the summer I fill the trenches between beds with whatever organic matter I have at hand, mostly mower clippings.  Each fall I till the trenches and scoop the half composted organic matter to the top of the beds.  Worms and other organisms work on the organic matter over the winter and the beds are ready to receive seed in the spring.  Onions, peas and potatoes are currently growing.  Row cover was placed over the peas to protect them from some predicted cold temperatures.  They made it through a couple of 20 degree nights with no damage.


But there are other things going on in the garden that easily take my attention away from the vegetables.  Several native prairie species are grown here for seed production.  The natives are not as well behaved as the vegetables.  These Prairie Dock will not stay confined to a bed and are continually increasing their territory.


The organic mix atop the beds seems ideal for germination of Prairie Dock seed.  I’ve decided to limit the Prairie Dock to one bed and they’ve just about taken that.


Clumps of False Gromwell last for three to five years before dieing.  In that time they produce huge quantities of seed.  Some of that seed manages to germinate and initiate growth of another clump.  False Gromwell are always in the garden, but their location is constantly changing.


Butterflyweed has claimed a three by three foot section at the end of one bed.  It came in as a volunteer and I let it stay.  That was about fifteen years ago.  Since then it has attracted swarms of interesting insects to the garden.  For the past three years it has hosted the caterpillars of the Unexpected Tiger Moth, an Ohio rarity.  The garden keeps losing ground to natives, but there’s still plenty of space for vegetables.


The cedar fence posts around the garden continue to expand their collection of interesting lichens.  It doesn’t take much for the lichens to distract me from my gardening chores.  I have yet to take the time for any serious lichen studies, but when I get around to it, there should be plenty of lichens here to get me started.


I am serenaded constantly while in the garden.  This Song Sparrow nests in an ornamental juniper that is kept in the garden just because birds nest in it.  It was planted there as a seedling 28 years ago along with several others that were intended for landscaping in front of the house, but it was not used.  Instead of getting rid of it, I left it there in case one of the junipers in the yard failed to grow.  By the time it became obvious that it wasn’t needed for landscaping, it had become a favorite nesting site of Song Sparrows, Catbirds and Cardinals.


Although not as melodious as the Song Sparrow, Henslow’s Sparrows call out their territorial warnings from perches in the tall Indian Grass surrounding the garden.  Since these birds return here every year and I hear them calling well into summer, I’m assuming that they are nesting.  It’s hard enough to see these birds in the field.  It would just be dumb luck if I ever encountered one of their nests.


A Burrowing Wolf Spider has claimed a territory near the Butterflyweed.  The burrow should be safe from disturbance in this location, so I will have time to coax the spider out for some photographs.


While on my knees looking at the spider hole, I glanced beneath the Song Sparrow’s juniper and saw this garter snake.  I think the garden is an appropriate place for this snake since, as a kid, I used to think their proper name was Gardener Snake.  This one kept doing strange gyrations with its tongue as though trying to convey a message in snake semaphore.  Maybe the message came through, because I suddenly thought of something I should be doing.  That’s how most of my garden forays progress; distracted by the native plants, distracted by the birds, distracted by the bugs and gone.

Burrowing Wolf Spider - 2011

When I have the time, I’ll stop and check every spider burrow I find. These are made by the Burrowing Wolf Spider, a spider that is considered rare in Ohio. It’s a species of Geolycosa, but I still don’t know which one.


The spiders hunt by ambushing prey that wanders past the burrow. They are often near the top of the burrow, but quickly retreat when you approach. Sometimes you can get them to reappear if you use a grass stalk to mimic the disturbance caused by an insect passing by the burrow. This spider is creeping up the burrow in response to that trick.


A little more teasing and he’s almost in full sight. This trick doesn’t always work, so I was pretty excited that he was responding so eagerly.


This is about as far up the burrow as I’ve ever managed to lure a spider. I’m on my knees and elbows almost directly above the burrow and I know that any movement on my part will send the spider back down into darkness.


I guess this spider is really hungry. At this point I’m trying not to move the grass that’s almost touching the spider’s leg. I’ve got sweat running into my eyes, tiny things are biting big chunks out of my legs and for some reason, the camera doesn’t want to focus properly.


The spider must have known that I was having camera trouble. It posed while I took 20 not quite focused shots. Finally I shifted my position and the spider shot back down the hole. The definitive photos will have to wait for another day.

Burrowing Wolf Spider

This is the Burrowing Wolf Spider, one of the species of Geolycosa. It patiently waits at the entrance to its burrow for small insect meals to wander by. The burrow is just over one-half inch wide.

Normally this is all you see. The vibrations made by your foot steps as you approach the hole, send the spider scooting down the hole for safety.

Somewhere between a few minutes and eternity, the spider will sneak back up to the entrance. This spider must have been hungry, because it was coming back up in less than a minute.

Finally, it’s back to its ambush point. There are no web tripwires around the burrow. The spider detects its prey through vibration and sight.

You normally see spider burrows in barren areas such as this. I don’t know if this is the preferred habitat for this spider or if it’s just too difficult to see burrows when there’s a lot of vegetation.
