Blue-Green Weevil (Pachnaeus litus).
These little bugs get a bad reputation, but such is the life of a weevil—the adults, such as this one, munch on plant leaves. The larvae fall to the ground and will munch on roots. This can be quite annoying in agriculture, especially citrus. For most plants, they aren’t much of a problem, but if they seem to get overwhelming, the USDA recommends the Trichogrammatidae family of wasps can help by preying on their eggs.
