HABITAT
Widespread around houses and outbuildings in northern Europe. Sometimes found in rabbit hutches, hence its name.
FOOD AND HABITS
Females found all year, males only in summer–autumn. Males have ridges and teeth under the carapace and abdomen, with which they create sounds to attract females.

Length to 15mm. Brown and rather mouse-like.
HABITAT
Ponds, lakes, dykes and sluggish streams across Europe.
FOOD AND HABITS
Builds a diving bell by trapping air in the middle of a sheet-like web spun among pond plants underwater. Visits the surface and collects air between the hairs on its abdomen, releasing this into the diving bell by stroking the hairs on its back legs. Lives in the bell, leaving it only to hunt for food such as small fish, tadpoles and other pond life. May spend winter sealed inside an old snail’s shell.
