- Females have a white “mustache” band of hairs below their large anterior eyes, while the adult males have a bright orange one.
- First jumping spider to have been officially recorded as having been seen eating an earthworm, a pretty uncommon meal for a spider that doesn’t spend much time on the ground (Ross 2008).
- Female spins a relatively spacious silken chamber around herself and then deposits her eggs on the floor of it, covering them with a thin layer of silk afterward. The finished “look” is reminiscent of a fried egg. She stands close guard over it until the babies emerge and disperse.
