Document Summary
Insects, birds, mammals, wind, water: trends in flower traits for specific pollinators. Beetles: white flowers, various odor, no nectar guides, nectar often absent, mangolias. Bees: bright cool colours, uv patterns present, mild pleasant odor, nectar guides, landing platform, nectar or pollen reward. Moths: white or pale, strong sweet odor, no nectar guides, nectar reward, open at night, no landing platform. Butterfly: bright warm colours, pleasant odor, tubular with landing strip. Hummingbird: no odor, bring red or orange, no landing platform, lots of nectar. Wind: dull colours, small petals reduced, no nectar, tons of pollen. Wasp: highly specialized, odors often mimic wasp scent. Plants with small flowers group together to attract pollinators. Nectaries hidden inside: located close to the receptacle so when pollinators get nectar, more pollen is brought close to stigmatic surface, nectar guides used to help pollinators locate nectar. Bees use uv light to see nectar guides.
