Last week when I was at a local garden I came across several pairs of ladybugs mating and several things really stood out to me.

First, the male ladybug is a lot smaller than the female. An article at ladybuglady.com (a great name for a website) points out that females are “usually” larger than males, but essentially it’s almost impossible for the average person to tell them apart until they are mating. If you really want to know how to tell male ladybugs from females the referenced article has photos from an electron microscope with detailed explanations.

The other thing that was obvious was the difference in color and spots between the two. The male is a medium orange with a few small light black spots and the female is a deeper shade of red with larger, darker spots. Wikipedia notes that there are more than 5,000 species of ladybugs (which technically are beetles and not bugs), with more than 450 native to North America. According to that article, the number, shape, and size of the spots is dependent on the species of ladybug. Does that mean these two ladybugs are different species?

Bugguide has some interesting factoids about names used elsewhere in the world for the ladybug. For example, “Ladybird” was first used in medieval England, perhaps because these beneficial predators of agricultural pests were believed to be a gift from the Virgin Mary—the “Lady.” Other European names have similar associations, such as the German Marienkäfer, “Marybeetle.” (Thanks to Gary for pointing out the correct spelling in German—I inserted the Umlaut to make it correct.)

So I am left wondering, will the little ladybugs that result from this coupling look more like mom or like dad?
