The l= arge aeschnas have been especially effected as they have large territories u= p and down the lake. They used to be very abundant just a few years ago but n= ow I seldom see them. Other insects up at Angevine have also declined marked= ly. For example I used to have a terrible time with wasps at the hummingbird= feeders. Now none!!
