General Information: Pincher bug, or odontotaenius disjunctus, is also known as ‘twice-stabbed’ beetles and their common name comes from the defensive position they take when they’ve been disturbed. These little guys will turn around with their abdomen and pinchers raised in the air to defend themselves. They can be found hiding under rocks, logs and other damp, dark places in your yard.
Description: Pincher bug are black and about 1/4 of an inch long. They have a red spot on each wing cover that’s visible when the wing covers are closed. As you can see below, they look kind of like earwigs except for their wings and size.
Life Cycle: The pincher bug is a beetle that lays its eggs in rotting wood where they hatch into larvae. These larvae then go through four stages before maturing into an adult beetle.
Diet: Pincher bugs feed mainly on decaying plant matter and fungi but will eat living plants if there’s nothing else around for them to eat.”
