We've had many reports in the last two weeks from people asking what those big green, buzzing, beetles are. Green fruit beetles (Cotinis mutabilis) are members of the scarab beetle family and are sometimes known as fig beetles or figeater beetles.

These beetles may also occasionally be found feeding on other plants with light-colored petals.
Some people believe they have the rose chafer or Japanese beetle in their landscape, however...
Spring is a good time to begin monitoring for any lawn insect pests. Pest examples include various root, crown and leaf-feeding caterpillars, grubs like masked chafers, billbugs and chinch bugs.
Although insects can be serious pests of lawns, lawn damage is more frequently due to lack of proper cultural care and/or improper grass species selection for your area. An unhealthy lawn is more easily attacked by insects, weeds and diseases.
Insects are sometimes are blamed for lawn damage when the culprit may actually be disease-causing pathogens, dog urine, or abiotic causes such as leaving an item on the lawn for some time and inappropriate use of garden chemicals such as fertilizers and herbicides.
