And while we're on the subject of insects, let's talk about the beautiful Ladybug -- another blessing from the insect world. It's considered good luck if the little Ladybug (in New England they're orange with black polka dots) lands on your person. When we were little, we would have to chant the following nursery rhyme before we blew the Ladybug off: Ladybug, Ladybug, Fly away home. Your house is on fire, Your children are gone. We always felt sad that the beautiful Ladybug had such a sorrowful situation to return to, though I don't think we ever really believed the nursery rhyme.
Ladybugs eat aphids, so folks with gardens and orchards (such as we were) welcomed the presence of the beautiful tiny orange beetle with black polka dots. According to the National Geographic, "Ladybugs lay hundreds of eggs in the colonies of aphids and other plant-eating pests. When they hatch, the ladybug larvae immediately begin to feed. By the end of its three-to-six-week life, a ladybug may eat some 5,000 aphids."
That may help us understand why, in a society that was once agrarian, a Ladybug's landing is always considered good luck.
