Thanks all good information! I will for sure plant that insectary! Meant to plant flowers for beneficials but didn't get around to it.
Ironically, there was a huge bug at the American Legion lodge where my band played tonight -- over an inch long, crazy looking thing. I let it crawl on a paper and took it outside -- took another look, it was a wheelbug! If I remember correctly they are a type of assassin bug and really good for gardens, I was tempted to take it home!
