Swallowtail butterfly from the other butterfly families are: Swallowtail butterflies practice Batesian mimicry, a behavior in which the butterflies' appearance closely resemble that of distasteful species that prevents predation. Swallowtails differ from many animals that practice mimicry. The tiger swallowtail butterfly ("Papilio glaucus"), exhibits a female-limited polymorphism for Batesian mimicry and others, such as the Canadian tiger swallowtail ("Papilio canadensis") do not display any form of mimicry. Predators include the red-winged blackbird, Pennsylvania firefly, five-lined skink, green darner, goldenrod spider, Chinese mantis, fiery searcher, and striped skunk. Not all individuals in some species are identical in appearance. For example, "Papilio glaucus" (eastern
Comma (music) to the syntonic temperament continuum, including meantone temperaments. In quarter-comma meantone, and any kind of meantone temperament tuning system that tempers the fifth to a size smaller than 700 cents, the comma is a diminished second, which can be equivalently defined as the difference between: In Pythagorean tuning, and any kind of meantone temperament tuning system that tempers the fifth to a size larger than 700 cents (such as 1/12-comma meantone), the comma is the opposite of a diminished second, and therefore the opposite of the above-listed differences. More exactly, in these tuning systems the diminished second is a descending
