Rose lovers have a special affinity for these dainty little insects since they eat aphids, which are the scourge of rose growers. These small beetles are not hermaphrodites as some people believe due to the gender-specific nature of their name. The males are slightly smaller than the females but their coloration and behavior are almost identical. They were named for the Virgin Mary, who was often referred to as the Blessed Lady after the farmers saw the beetles saving their crops from pests. In Germany, their name is Marienkafer, which translates to Mary beetle.
