|This spider occasionally is seen on walls
or ceilings of houses (unlike
spiders and tarantulas that do not climb). The giant crab spider walks
around in search of insect prey at night, but usually hides during the
day. Despite its appearance, the giant crab spider is not dangerous to
humans (though the bite can be painful).
Crab spiders get their name by
their ability to rapidly move sideways, like a "crab".
Giant crab spiders are found throughout Arizona and
Sonora in a variety of habitats including: in dead saguaros, under rocks
and in homes.
