There are 4.000 species of ladybugs in the world and up to 150 varieties in the United States alone. They were first introduced into the Unites States from Australia.
They are categorized as insects because they have three main portions of their body: head, thorax, and abdomen.They have poor eyesight and rely on their antennae for touch and smell. In the winter they go dormant and in the spring mating occurs. The male and female are attracted to each other by smell. The female can lay from 2 to 50 eggs in a day!
Ladybugs: A Natural Pesticide
Many farmers and gardeners consider ladybugs a natural pesticide. They eat tiny insects called aphids which feed on the sap in plants. Aphids are common garden insect pests that feed in colonies. An infestation usually causes mold and plant leaves to curl and dry out.
Female ladybugs are larger than male ladybugs and can eat up to 75 aphids a day while a male can eat around 40 per day.Ladybugs in both the larval and adult stages feast on these insects. During its lifetime, a lady big will eat over 5,000 aphids!
The best time to release ladybugs in your garden is typically early during the growing season on a cool evening. A great place to release the ladybugs is an area where they can find food and water. Planting plants close together helps to maintain a humid environment. Ladybugs are attracted to plants with umbrella shaped flowers or leaves, such as angelica, caraway, cilantro, dill, fennel, tansy, wild carrot and yarrow. Ladybugs also are drawn to cosmos, coreopsis, dandelions and scented geraniums.
