Lady beetles are invaluable in your garden, especially if your are an organic gardener. And on that note if you don't use chemicals and insecticides in your garden you won't kill the Lady Beetles and the Spiders and you'll have less pests naturally.
beetles as well as being beautiful little creatures are natural enemies
of many insect pests, a single lady beetle may consume as many as 5,000
aphids in its lifetime.
Lady beetle's have a
hemispherical to oval body shape. The head is covered by a hood called
the pronotum. They may be white, yellow, pink, orange, red or black,
and usually have spots. These spots are a warning to other animals. 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.
females usually lay their clusters of eggs in the vicinity of aphid,
scale, or mealybug colonies. The alligator-like larvae are also
predators. They are spiny and black with bright spots. Although they
look dangerous, lady beetle larvae are quite harmless to humans. After
feeding on insect prey for several weeks, the larva pupates on leaves.
Adults tend to move on once pests get scarce, while the larvae remain
and search for more prey.
Bad Lady beetles... these are
the yellow ones with black spots. Often called Mexican bean beetle and
the squash beetle, you'll find them on your beans, peas and squash. They
eat plants and not insects... but hey, don't kill them, I just pick
them off and take them off to the bush (forest) or park, after all they
have a right to exist like all life.
