The Carpenter Bee gets its common name from its habit of boring into wood to make galleries for rearing its young. You may find a little pile of sawdust where this insect has been at work. The adult is about 1/2 to 1 inch in length and the top surface of its abdomen is bare and shiny. This insect is found throughout the world, with seven species found in the United States.

You can read more about carpenter bees in Entfact 611 -- Carpenter Bees.


The Common House Centipede (centipede = "hundred feet") gets its name from its many pairs of legs. It is normally found in moist areas under mulch, rotting logs, stones, or piles of leaves, but it also frequently enters houses, where it may be found around sinks and drains. Although it looks fearsome, it is harmless to people.

It is a predator and feeds on small insects and spiders. In fact, if it eliminates a few household pests, you might consider it a beneficial visitor! It can inject venom with its poison jaws to kill its prey. Most have very small jaws that can not break human skin.

Have you heard this one?

One centipede to another: "I just hate it when I start the day off on the wrong foot."
