White Micrathena - A Spider Wearing a Hat

(Reposted on 10/20/2008 as it is time for the fall spiders again!)
This past Sunday evening, I decided to take a stroll along a trail that winds through the woods near my house. My mission- to boldly walk into as many spider webs as I possibly could. It didn't take long. First I came across a Barn Spider. This hairy, steroided appearing arachnid had just began setting up shop- that is, building her web for a nice evening of insect dining. I decided to bypass her. I don't mess with scary looking spiders. (Clicking on the Barn Spider link above will take you to a photo of the VERY spider that I almost bumped into.)

So, I continued walking- and it wasn't long (less than five minutes) before I walked into another spider web. This web belonged to the tiny White Micrathena. Comparing the diminuitive size of the White Microthena to the large, bulky size of the Barn Spider is like comparing a Chihuahua with an English Mastiff. The White Micrathena is smaller than my pinkie fingernail. These spiders aren't scary.

As with the Spined Micrathena, the White Micrathena specializes in creating "face level" spider webs. If you suffer from arachnophobia- then walking through the woods in the Fall isn't a good idea- you WILL get plastered with spider silk. (One method to help prevent spider web plasterings: have a person or two walk in front of you to clear the path- just a tip. Another free, albeit unrelated tip- if a bear begins chasing you- don't try to out run the bear- just try out running your hiking partners.)

The scientific name for this spider is Micrathena mitrata described by Nicholas Marcellus Hentz in 1850. For those of you who have been reading my blog entries- all 4 of you, you may remember that Mr. Hentz had also described a couple of other spiders already listed on this site: The Bowl and Doily Spider and the Green Lynx Spider. I discovered from bugguide.net that the English translation for Micrathena mitrata is "turban wearer." I had to laugh. If there is one thing that I like- it is a scientist with a sense of humor. (I began performing research on Nicholas Hentz because of his sense of humor in naming this spider. He was a fascinating man who had emmigrated to the United States from France. I am working on an article regarding his life- I plan on posting it within the next few days. This scientist once lived in Florence, Alabama. I was raised in a suburb of Florence.)

The following is an excerpt from Hentz's observations, in which he describes the spider- but instead of describing the spider's abdomen as a "turban" he describes it as a a "bishop's mitre" (he was raised Catholic.) Looking at the photo of the spider above- I believe Mr. Hentz was right- it does look like a Bishop's hat!

Cool spiders. Occasionally a Lynx spider will take up residence in my lantana - I think that's what they're called. They're scary looking, too, but not as large as the Barn Spider. Spiders are fun, but I hate it when they catch butterflies and hummingbird moths, which are passions of mine.
