Flowers that are insect-pollinated are called ''entomophilous''; literally "insect-loving" in Latin. They can be highly modified along with the pollinating insects by [[co-evolution]]. Flowers commonly have glands called ''nectaries'' on various parts that attract animals looking for nutritious [[nectar]]. [[Bird]]s and [[bee]]s have color vision, enabling them to seek out "colorful" flowers. Some flowers have patterns, called [[nectar guide]]s, that show pollinators where to look for nectar; they may be visible only under [[ultraviolet]] light, which is visible to bees and some other insects. Flowers also attract pollinators by [[odor|scent]] and some of those scents are pleasant to our sense of smell. Not all flower scents are appealing to humans, a number of flowers are pollinated by insects that are attracted to rotten flesh and have flowers that smell like dead animals, often called [[Carrion flower]]s including ''[[Rafflesia]]'', the [[titan arum]], and the North American [[pawpaw]] (''Asimina triloba''). Flowers pollinated by night visitors, including bats and moths, are likely to concentrate on scent to attract pollinators and most such flowers are white.
Still other flowers use mimicry to attract pollinators. Some species of orchids, for example, produce flowers resembling female bees in color, shape, and scent. Male bees move from one such flower to another in search of a mate.
