I was checking out the flower border and noticed that nearly every blossom on my white chrysanthesum was hosting a copulating pair of some kind of beetle. It was shaped like a firefly but had some kind of yellowish tan upper wing. There were also some on the yellow blossoms as well as several cucumber beetles. But the rust mums and the autumn joy sedum blossoms seem best free. Any idea what. Should I be trying to get the sprayer working? Internet search didn't turn up a picture that looked like my bug. - Paula -
