Cteniza moggridgei

Cteniza moggridgei is a species of trapdoor spider found in France and Italy.^[1][2] On the Ionian Islands, their nests are often found among the roots of olive trees. These nests are sometimes found clustered together, but their proximity is not necessarily a sign of their sociality.^[3]

Its nests are rarely on flat ground, more often found on sloping to vertical banks so that gravity naturally pulls the door closed.^[3] 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.^[3]
