With the ecological mistakes of man now becoming more apparent, it is reassuring to know that nature can establish certain controls, which prevent some destructive insects from overpopulating the environment.
Man can encourage and prepare the conditions for an increase in insect predator populations.
First we must be able to identify the beneficial insects. The ladybird beetles are small, oval, convex and often brightly colored insects. Most of this family is predaceous both as larvae and adults and feed chiefly on aphids. They are found frequently on vegetation where aphids are numerous. They hibernate as adults, common under leaves and debris in large aggregations.
