The Cabbage White is perhaps our most familiar butterfly after the Monarch. What is not generally known, however, is this medium-sized ubiquitous butterfly is an invasive species, accidentally introduced onto North America at Quebec in 1860. There is no other butterfly that is so successful over such a large variety of landscapes and climates. Here in the Midwest, this butterfly is everywhere, usually in large numbers. Farmers and gardeners consider the Cabbage White a pest species; its caterpillars have a ravenous appetite for radishes, cabbage, and nasturtiums.
The sex of cabbage butterflies can be readily determined. In addition to the dark spot at the outer “corner” of the forewing, upper (dorsal) side, females have two dark spots mid-wing, one above the other; males have only one. So right away you can study the proportion of females versus males over the season.
The one captured here leaving my garden today is a male. We will be on the lookout for any caterpillars that might want to enjoy our tasty garden!
