Beneficial garden ladybugs for controlling pests in your garden are the most popular and widely used beneficial insects for commercial and home use. Ladybugs are capable of consuming up to 50 to 60 aphids per day but will also eat a variety of other insects and larvae including scales, mealy bugs, leaf hoppers, mites, and various types of soft-bodied insects. Ladybugs, also called lady beetles or ladybird beetles, are a very beneficial group of insects. Ladybugs are natural enemies of many insect pests and it has been demonstrated that a single ladybug may consume as many as 5,000 aphids in its lifetime. Ladybug adults have a very characteristic convex, hemispherical to oval body shape. The head is covered by a hood called the pronotum. Many species of Ladybugs are present in North America and they are common in most habitats across the commonwealth. They may be white, yellow, pink, orange, red or black, and usually have spots.
Ladybugs are among the most familiar beetles, easily recognized by their round, often spotted bodies, less than 1/16-3/8″ long. Most are shiny red, orange, or yellow with black markings, or black with red or yellow markings. Both adults and larvae are predators, mostly of aphids. They are common on plants and often over-winter as adults in large swarms under fallen leaves or bark. In the West huge swarms of Ladybugs fly into mountain canyons, over-winter under leaves, and return to the valley in the spring. If food supply is good there are many generations a year.In fact, this is a type of warning coloration to other animals that may try to eat lady beetles. Like many of other brightly-colored insects, ladybugs are distasteful to predators. When disturbed, they may secrete an odorous, distasteful fluid out of their joints to discourage enemies. Did you ever see a little red and black beetle crawling along your window sill? It was probably a Lady beetle or just Ladybug as most people call them. Most species of Ladybugs are among our most beneficial insects as they consume huge numbers of plant feeding pest insects, mostly aphids. This fact and their attractive appearance have contributed to the generally good opinion of Ladybugs by most people. For instance, the French call the Ladybugs les betes du bon Dieu or creatures of God. Ladybugs belong to the beetle family Coccinellidae which means Little sphere. There are probably 4,000 species found world-wide and over 350 in North America.
Life Cycle and Habits
The length of the life cycle varies depending upon temperature, humidity, and food supply. Usually the life cycle from egg to adult requires about three to four weeks, or up to six weeks during cooler spring months. In the spring, overwintering adults find food, then lay from fifty to three hundred eggs in her lifetime (tiny, light -yellow eggs are deposited in clusters of 10 to 50 each) in aphid colonies. Eggs hatch in three to five days, and larvae feed on aphids or other insects for two to three weeks, then pupate. Adults emerge in seven to ten days. There may be five to six generations per year. In the autumn, adults hibernate, sometimes in large numbers, in plant refuse and crevices.
