They are active predators, hunting invertebrates (including other spiders) among vegetation.

Their body color ranges from pale white to yellow, orange, or green; with a pattern of black, orange, and white longitudinal lines.

[1][2][3] The species was first described in 1878 by the German arachnologist Ludwig Carl Christian Koch.

The specific name is from Latin macilentus ("lean" or "thin"), in reference to the spider's body.
