SNAKE-BACK SPIDER - SEGESTRIA SENOCULATA


Body length : 9-10 mm – Body + Legs : 19-21 mm

This spider builds a tubular web in small holes in walls or crevices in bark.
It darts abruptly from the nest to catch the preys which touch the trip lines fanning out from the entrance.

Male and female are almost similar. The male is smaller with shorter and slender body.

This species can bite, involving some pain during several hours.
These pictures show two spiders, one slightly larger than the other. The largest was present one day before the second arrives.
Both remain motionless at some distance from the web.

Longueur du corps : 9-10mm – Longueur totale : 19/21 mm

Cette araignée construit une toile tubulaire dans des petits trous de murs ou dans une crevasse dans l’écorce des arbres.
Elle se précipite hors du trou pour capturer les proies qui touchent les fils de soie étalés en éventail à l’extérieur de l’entrée.

Mâle et femelle sont presque semblables. Le mâle est plus petit avec le corps plus court et plus mince.

Cette espèce peut mordre, entraînant des douleurs pendant plusieurs heures.
Ces photos montrent deux araignées, l’une légèrement plus grande que l’autre.
La plus grande était présente un jour avant l’arrivée de la seconde.
Les deux restent immobiles à une certaine distance du nid.
