Insects

 

We continue to wait and watch for the brown marmorated stink bugs to be resting on the south side of the house or entering to spend the winter.   In the past 2 weeks samples were received from Burlington and Indianola for new county records, bringing us up to 8 counties in Iowa where BMSB has been confirmed.  Please let us know if you spot anything similar to the photos below.  Send reports with attached images to insects@iastate.edu.   Read more about BMSB.

 

As leaves are falling is the time to watch for nests of the baldfaced hornet.  After the first freeze the nest can be collected for show-and-tell with little risk of being stung.  Read more about nest collection and preservation on the Clinic website.

 

Millipedes!  Millions of migrating millipedes continue to annoy some homeowners.  It's hard to explain how there can be so many millipedes after two years of drought, but there they are.  Thousands on the driveway overnight.  Yuck.  Sweep up and discard.
