Oh Bugger :: What's Buggin' Out On Thursdays?



I'm a self-proclaimed naturalist researching the "bugs" in my life.  I use the term "bug" lightly and in very general terms so I include insects, spiders, and other related creatures.  I try to share a new bug every Thursday (but do not always get a chance).

My camera is a Canon Powershot G7.  As an amateur photographer simply pursuing what interests me, I've found that I truly enjoy taking photos of bugs and doing my best to identify them and learn more about their habitat and biology.
My Philosophy: To take photos of Texas wildlife and local insects in their environment without disturbing them or causing them harm.  My goal is to capture their likeness in a photograph, identify the specimen by research using credible internet resources, and share what I've learned with others.
Have you heard?  Buggin' Out On Thursdays has it's own index list including article titles, specimens, and dates published so you can find what interests you easily.

I often contribute my photos to the field guide at BugGuide.net and can be found there as biologie.

Buggin' Out On Thursdays :: Crabby Spider Promises She's Not Shelob's Sister

Peaches The Ground Crab Spider
Xysticus species

"Don't squish me! I look wicked like Tolkien's Shelob but I'm not interested in biting you or Frodo!"

I was sweeping the kitchen floor the other day when I looked down at my little pile of dirt and spied a very creepy looking spider. A little yelp of surprise escaped from my lips and I went into fight or flight mode for a second but the spider just sat there quietly. From my vantage point I thought it might be a Mutant Giant Tick like one you'd see in an old Sci-Fi Flick! Yikes. Then I thought maybe she was Shelob's baby sister. Again, yikes.

Once I figured out the "thing" wasn't going to come skittering after me like a ravenous monster it didn't take long before I had slipped a sheet of paper under her and placed a glass jar carefully over her so I could get a closer look. The spider remained very still. Not long after that and I had removed the jar and started taking macros so I could run to BugGuide.net and see what everyone thought about my new "bug".

Mandy at BugGuide was very helpful - she's Spiderwoman! She mentioned the star of today's blog post is a spider whose species has not yet been identified in the guide. My spider and the rest of her species are a uniform peachy red (in low light she may even look brownish until you get her out in the sun). I learned the only way to truly identify a spider at the species level is to have an entomologist study the adult spiders "private parts". The appropriate term for this on a female spider is the epigynum (to learn more check out this short article at Museum Victoria). I sure wish I had taken some underbelly shots of my buddy, Peaches, so I could help identify her species for the guide. Maybe next time!

Here are four fast facts about ground crab spiders:
  • They are not poisonous to humans
  • They aren't normally found in the home and hunt outdoors
  • Rather than spin a web, they lay in ambush for prey to pass by
  • Crab spiders can walk forwards, backwards, or sideways - just like a crab!
It's Buggin' Out On Thursdays!

What kind of bugs have you seen lately?
