Depending on the pollinators they hope to attract, different kinds of cacti generate different flowers. While bees are the most frequent pollinators of cacti, other insects such as butterflies, moths, hummingbirds, and bats may also be drawn to the flowers of cacti in desert regions. Bat pollination of flowering plants is not very frequent. However, a large percentage of cacti species are focused on luring bats, who may travel great distances between scarce communities of cacti in semi-desert and desert habitats.These cacti produce flowers that often bloom at dusk and in the evening, are less vividly coloured than conventional cactus flowers, have a musty odour and yield a lot of sugary nectar.
