P. Wasps: The enemy of my enemy

A Parasitic Wasp   (Public Domain)
There’s an old saying:  The enemy of my enemy is my friend.

The average person doesn’t think of wasps as friends.  In fact, humans often reach for bug spray when wasps appear.

Scientists, however, are reminding folks that there are creatures even more to be shunned than wasps:  emerald ash borers.  These are “invasive beetles whose larvae have destroyed trees across vast swaths of northern and eastern America in just a few decades.”

Not a tree hugger?  Consider this:  These timber hosts are worth approximately $280 billion, and to replace them would cost an additional $25 billion.

Since parasitic wasps do away with emerald ash borers, the former are looking a whole lot friendlier to lumberjacks and such.  The U. S. Department of Agriculture is therefore “releasing millions of wasps into 24 states.”

So if a parasitic wasp flies by, tip your hat.  Don’t worry, you won’t get stung:  This new buddy has smaller fish to fry.
