Despite having lady in their name, not all lady bugs are ladies. Lady bugs are beetles. Their bright red color keeps predators away, warning them that they will be poisonous to ingest. In the lifetime of a lady bug they have been known to eat over 5,000 aphids. This is very helpful to farmers as aphids can destroy crops. Lady bugs are called Lady Birds in Europe and their “common” name is thought to be from the middle ages when farmers would pray to the Blessed “Lady” or the Virgin Mary to help their crops not be destroyed. It was the “lady bugs” who would always come to the rescue!
