Family Philodromidae

Tibellus oblongus


Genus Philodromus

The spiders of this genus can be recognized by the fact that the second leg pair is longer that the other legs. Their size varies between 3 and 7 mm.
Philodromids are 'quiet' spiders that are well camouflaged but can run very fast to escape or pursuit their prey. When they flee, they run sideways.
The difference between male and female can be great, as the pictures of the Philodromus dispar shows, but in other species, the sexes may be similar.
