Why are ladybugs considered a "beneficial" insect? Ladybugs feed on aphids and other soft bodied insects that feed on plants. The ladybug feeds on these pests as the adult ladybug and as the larva. One ladybug can eat as many as 50 aphids a day.
Our good and lucky bugs, the ones we learned to treat like gems and recite poetry to. "Ladybug, ladybug, fly away gone. Your house is on fire and your children are home." Did a ladybug ever land on you?
