Minute Pirate Bugs are Biting - ARGH!

The nicest, sunniest, warmest days of autumn are when most of us first notice the minute pirate bugs (also called the insidious flower bug).  While we're enjoying the sunshine the pirate bugs are casting about looking for just-one-more meal before winter sets in and shuts them down until next spring.  The distinguishing characteristic of oval-shaped, black-and-white minute pirate bugs is that when they land on your bare skin they bite with a pain that is way out of proportion to their minute size (1/5th inch).

Asian Jumping Worms

Recent requests for information from Master Gardeners and others have prompted us to share what we know about "jumping worms," another in a long list of invasive species that could have a negative impact on our landscapes and natural areas.  In the words of Gilda Radner, "It's always something. If it isn't one thing – it's another."

European Paper Wasps Are Widespread

Four, short years ago we announced we were watching the spread of another invasive into the state of Iowa.  The European paper wasp, Polistes dominula, was first reported in the US in 1978 near Boston, but it was slow to gain our attention until this decade.  In August, 2012 we reported it as relatively new to the state.  Now, in July, 2016, it seems to be everywhere and in some areas it is the only wasp seen around the house.
