At first glance this spider looks very similar to an ant. Jumping spiders of the genus Myrmarachne may imitate ants in both appearance and behavior. By mimicking an ant the spider might better avoid predators like spider wasps. Some ant mimic spiders may even prey on ants or the homopteran bugs they tend. Ants have three body segments while spiders have just two. Note how this spider's forward body segment has been adapted to give the overall body an appearance of three segments. The spider also waves it's front pair of legs giving the appearance of antenna. The spider's huge forward-facing eyes are a dead giveaway that it is a jumping spider. Jumping spiders (family Salticidae) have remarkable binocular vision which they use to locate, stalk and ambush prey. Though they are "jumping" spiders these spiders may only rarely engage in such non ant-like behavior. Ant-mimic jumping spiders are nevertheless very active and it was pure luck that I encountered this spider as it rested while feeding. In the past six years I have only encountered this type of spider three times in the forests where I walk.

This spider was encountered and filmed at an altitude of roughly 600 feet above sea-level and amidst the dense green forests of Nippondaira in central Japan. The Nippondaira is a small, isolated range of low coastal mountains between the cities of Shizuoka and Shimizu. This area is within Shizuoka prefecture and relatively close to Mt. Fuji. The spider was filmed in late June during the annual rainy season.

The following poem was submitted for this video by YouTube member "reymiland":

"A spider
that looks
like an ant,
Can jump,
like a
little ant..
..can't. "

The Path of Wildness is easy to find
The course of a stream
Leaves blown in the wind
A beast's track through the brush
And the direction of our first inclination

The Path of Wildness is an answer and response to a prescribed way of life which may leave some individuals with a sense that their living is little more than a series of pre-determined, step-like episodes between birth and death. The stages of living between these events: childhood, adolescence, adulthood, parenthood and senior are themselves natural and in accord with the needs of the species and most individuals. Many find their satisfaction in living this course and to these individuals I have little or nothing to say. Others though long for something more; something innate, genetic and seemingly calling. Adventure and change can give a degree of satisfaction and relief yet even these may seem too tame. To those who feel drawn to something beyond the entertainment and stimulation of senses I offer a walk along The Path of Wildness. Don't bother penciling the event in your schedule, preparing a pack with goodies and supplies or even inviting a friend along, for this experience is along the course of your first inclination and you must surely always go alone.
