Tibellus oblongus is a spider from the family of running spiders (Philodromidae).

features

Tibellus oblongus reaches a body length of 8 to 10 millimeters. The species is very reminiscent of an extensor spider due to the elongated abdomen and the legs, which are snuggled close to the body in the resting position , the third pair of legs is also strongly kinked here. However, Tibellus oblongus can be distinguished from an extensor spider due to its somewhat scaly, clear hair. The basic color of the female is light yellow-brown, in the middle of the front and back of the body there is a dark brown longitudinal band, the sides of the abdomen are also darkened, between the dark longitudinal stripes there are lighter, narrower longitudinal stripes and in the rear part of the abdomen two or less often four black dots. The male is drawn much darker and more contrasting. The basic color of the male is more light gray with almost black longitudinal bands.

Occurrence

Tibellus oblongus occurs in Europe. It can be found in both damp and dry places. However, it always prefers well-sunlit areas, such as wet meadows, waterfronts or heather areas, especially on sandy ground.

Danger

The species is widespread, common in suitable habitats , and is classified as “not endangered” in Germany on the Red List.

Way of life

The spider is difficult to find in the vegetation with its stretched legs and narrow body shape. However, in contrast to the similarly built extensor spiders, it does not create webs, but overpowers prey, like all running spiders, with quick access.

When mating, the male sits almost at right angles to the female when the tarsus is inserted. The male's front body points downwards. In midsummer the females sit protectively over their egg cocoons . This is narrow and elongated on thin stalks, but disc-shaped on a flat surface. In the course of time, the coloring of the nesting female becomes gray and less contrasting, and finally the black points are also lost.
