Cteniza moggridgei is a species of trapdoor spider found in France and Italy.
[2][3] On the Ionian Islands, their nests are often found among the roots of olive trees.
[4] Its nests are rarely on flat ground, more often found on sloping to vertical banks so that gravity naturally pulls the door closed.
[4] The trapdoors have a cork-like lid that is not flush with the surrounding surface when shut, as is normal of this type of trap.
Instead, it has short spur-like protrusions above and behind the hinge that serve as a lever to make raising and lowering the lid easier.
