Ladybugs are a form of beetle. They are mostly 1/4"
long with a domed back. Commonly the wing covers can be red or orange coved with
black spots. Depending on the species though,
many varieties have no spots or can be other colors. The head and legs
in most are black. There are over 450 species of ladybugs in North America.
Ladybugs lay their eggs primarily under the leaves of plants
that have a source of food. In most cases, they are looking for aphids. The
larvae will hatch a few days after being layed. Ladybug larvae look like
miniature alligators. Most are black with reddish marking and can look spiky or
bumpy. The larvae are usually about 1/4" long. The larvae will grow fast
and shed their skin several times for about 2 weeks. The larvae are voracious and can eat 40 to 80 aphids an day. When they are full
grown, they will attach themselves to a leaf and form a pupa. In about 2 weeks,
they will become an adult ladybug.
A ladybug can live
one to two years and lay over 1000 eggs. If it is under stress, it will release
a bad smelling chemical to deter predators. Its bright colors are a warning
that it will not make a good meal. Ladybugs will also play dead and drop
lifelessly to the ground if attacked.
Most species of adult ladybugs are considered beneficial
insects for gardeners and farmers. An adult
ladybug and larvae will remove aphids, whiteflies, lace bugs, mealybugs, scale,
spider mites, grape root worms and the
larvae of most other insects. Over its life, a ladybug can consume up to 5,000 aphids
or soft bodied insects. Ladybugs will also consume pollen and nectar.
Legend has it, that the "lady" in ladybug came
from farmers in the Middle Ages praying to the Blessed Lady to save their crops
plagued by pests. Soon after many prayer meetings, farmers stared seeing
ladybugs in their fields and began calling the them lady beetles.
You can attract ladybugs into your garden by providing small
flowering plants like bugleweed, butterfly weed, cilantro, dandelion, dill,
fennel, oregano and thyme.
You can also purchase ladybugs to release into the garden or
your farm. If you purchase ladybugs, you need to release them immediately, or
store them in a refrigerator for 1 to 3 weeks. Purchase ladybugs from companies
that ship next day with food and water in the packaging.
Before releasing the ladybugs into your garden, mist the
plants to provide a source of water. You can also mix a few tablespoons of
sugar into a spray bottle filled with warm water. This will dramatically
increase the amount of ladybugs that will stay in the area and start to
reproduce.
Release the ladybugs at sundown, because they rest and don't
fly at night. You can spread out the release over the leaves of the plants. If
ladybugs fall to the ground, they will climb up the plants.
The ladybug is considered good luck in almost every culture
around the world.
