OK, I think it was a spider, at least an arachnid, but here goes the description:
Color: the prosoma was black. The opisthosoma, orange * and was sometimes carried up at a 90º angle*. The terminal segments/joints of the front legs were a light, light orangish color. The rest were all black.
Body: Prosoma and opisthosoma were longish and roughly the same size. About as thick as a match and as long as my thumbnail ('bout ½ inch). The pedipalps looked really long. It seemed to walk like a *daddy-longlegs; i.e., with the joints of the legs higher than the body.
It was just ambling around on a vine. There was no evidence of a web.
Anyone??? I’m not an entymologist, and at times like this it really bugs me.
*Or like the mechanical spider on Jonny Quest that was operated by the evil Dr. Zin.
