This small jumping spider can often be seen on the walls of buildings. It is 5-7 mm in length and can be recognised by its hairy body with black and white stripes on it (for which reason it is sometimes referred to as the "zebra spider"). In the Salticidae the eight eyes are distributed around the carapace in a single row, unlike those of most other species. Prey is normally first detected by the lateral eyes, and the spider will then jump round to face the prey and localise its position using its large frontal eyes. The eyesight of the Salticidae is among the best of any spider. The adult males have enlarged, projecting chelicerae, which are used to spar with other competing males.These can just be made out in the photo, which is of an adult male. |
