Spiders are one of the few good guys that can capture and destroy flying meanies. They can even snare grasshoppers three times their size. A web or two near the garden means the good guy spiders are on patrol guarding the vegetables, so leave them alone. There are also some wasps that parasitize various caterpillars and other insects, he adds. These wasps are tiny and black, with big eyes.
Most people never see parasitic wasps, but they are out there trying to control the bad guys.
Be on the lookout for them, and leave them to their duty. If you are not sure if the insect you are seeing is good or bad, don't assume it's one of the evil members of that group. Get it identified before doing anything rash. A current exhibit in the Chase Fine Arts Center Tippetts Exhibition Hall honors Edwards' career and marks his retirement. The exhibit, which features work by former Edwards' students, has been on display for several weeks.
