The violet patches on the three petals of the mariposa lily serve as nectar guides to its many pollinators, especially beetles. Photo by Gene Yates.

After the leaves are dead you can cut them back and just leave the bulbs until next year when many will bloom again. High quality bulbs should come back for about 3 years, but they do get weaker year after year. I would like to receive my spring bloomers (like tulips, daffodils, etc) in spring/summer.
Wait for the tulips to grow and bloom this spring and then do the major cleanup. You may want to dig the bulbs after the foliage has died back and replant the bulbs. You can put some gravel or chicken wire around the bulbs in the soil to discourage voles and squirrels to dig and eat the bulbs.
