The lily leaf beetle lays eggs and completes its life cycle exclusively on true lilies and fritillaria (daylilies are not affected). The cotyledons, or initial leaves ,will poke up from the soil and become green as the initial chlorophyll pigments are formed and photosynthesis begins.The juvenile plant will continue to grow, forming more leaves and roots as more food is produced during photosynthesis and the roots continue to absorb water and nutrients.

Surrounding the pistil is a ring of six male-gendered stamens, each with a thread-like stem called a filament and topped by the pollen-shedding sacs in the anther.The six petals attract visual attention to pollinating insects who frequent the stamens for pollen and the sweet nectar of the style.
