The sow bug killer has large, strong fangs, which enable it to bite through the hard shell of pill bugs and sow bugs. It is generally beneficial, but may bite people.
You just never know what you will find when you turn a rock over. These two sow bug killers were among the many animals which were under this rock in my garden.
This little silk bag apparently was
the remains of the nest of this sow bug killer. It kept trying to
squeeze into the bag.
