I live in NE TN and about this time each year we have ladybugs. As an organic gardener they are great for cleaning up before up take out my plants plus they are a joy to watch. We have see 0 ladybugs…lots of stink bugs though. Do you know if they have been killed off by the extremely wet weather or is it something more nefarious like Monsanto crops killing them like they do the honeybees. Thanks.
We aren't sure why your populations are down but there seems to be a study going on thorughout the US on that very subject. Hopefully, this can be of some help to you. Also, you might consider sending in your findings for TN.
