Despite their abundance, the best advice is to hold on until the lady beetles and flower flies move in to kill them. Three weeks from now most of the aphids will be under control. If you have to do something, homeowners should squirt them with a hose and knock them off. The end of the euonymus scale crawler period is rapidly approaching. No one yet has reported any singing - it has been cool weather.
Gene maintains a website on the cicadas.
Brood X is apparently what is appearing now. It was last seen in 1987. It began to emerge this weekend in NE Marion County and maybe in other areas also. Gene said that many were emerging in the Cincinnati area. If any of you are aware of local emergences of the periodical cicadas, it would be useful to hear from you reporting the county, the time when they began to emerge, and how heavy the emergence is - a few, or thousands, or whatever.
