| [Note Guidelines] Photographer's Note |
It's a lucky shot in so many ways. Firstly, because of it caught my eye and I recognised from a distance what I see. Secondly, I had got enough space to go closer to them. Thirdly, I managed to focus on them (I know it is not perfect but the wind blew so this was the best I could do). Well, I wanted to do a better composition but "thanks" to the wind that's what I got.
Anyway, I hope you like it.
Bark crab spider
Family tree:
Araneae thomisidae xysticus
Spiders of this family have a distinct crab-like appearance. Legs I and II are much longer and stouter than legs III and IV. Legs I and II are held out to the sides and project forward while legs III and lay backward against the body. Body hairs are simple and erect. Lateral eyes are elevated on tuburcles. Xysticus species come in various shades of brown and gray, and frequently bear white or yellow markings. Body is compact, broad, and wider than it is high. There are two claws on each tarsus. Males ( around .10 inch) are smaller than females (around .40 inch) Colors and markings are quite variable within species. Before mating the female is offered a present and secured by some silk threads. These threads are so tiny that it does not fasten her for real but she pretends it does. Crab spiders do not spin webs. They are wandering predators that secure prey by stealth and ambush. They are crab like in motion, moving sideways, backwards, or forward. Females guard egg sacks, but normally die before spiderlings hatch. Some species are capable of changing color to match their surroundings (over a period of days). They tend to be forest dwelling, living on and under loose bark, under leaves and stones on the forest floor, and on low lying vegetation.
