Calochortus amabilis,commonly known as Diogenes Lantern, grows only in 
California. I wish to learn the pollinators of this plant and why the flower 
turns red/orange after pollination occurs (Does this coloration discourage 
pollinators from visiting an already pollinated flower? The red color of 
autumn Maple leaves is the result of stored sugars. Is the red I see in the 
Calochortus amabilis flower also the result of stored sugars? Does this red 
color discourage insects, animals, or birds from eating the ripening ovary?) 
Why are there “hairs” on the petals of members of the Calochortus family? Do 
these hairs brush pollen grains off visiting insects and thus increase the 
chances of successful pollination?  Is being a “Generalist” as opposed to 
attracting “specific pollinator” actually a good thing? In years when one 
population of pollinators suffers ( such as the honey bee being attacked by 
parasitic mites) is the Calochortus amabilis population able to maintain as it 
still attracts other pollinators (such as beetles)?
