Harvestman

I passed this lovely long legged creature while I was walking in Boundary Creek Park in Moorestown, New Jersey. Click on the photo to enlarge it. Years ago I would have thought it was a tremendously big spider; it was about 4 or 5 inches from leg tip to leg tip. But it's not a spider. It is a member of the large arachnid order Opiliones, usually called by the common names of harvestman or harvester, daddy-longlegs or granddaddy-longlegs. The opilionids don't spin silk and don't make webs. They don't make venom. Their bodies are not divided into 2 segments with a "waist" like spiders. Many but not all of the thousands of described species of harvestmen have these extremely long slender legs. I always find them like this, sitting motionless upon leaves, possibly waiting for unsuspecting prey like an aphid, mite, caterpillar, or whatnot to stroll past, but maybe just taking in the summer day.
