Here is illustrated picture of Lily Beetle (Lilioceris lilii) life cycle with brave explanation.

1. Eggs Stage. The eggs of red Lily Beetle are lain in rows of about 2-15 eggs on underside of leaves. The size of these eggs are about 1.0 x 0.5 mm and orange in coloration with a sticky orange-red secretion, which help the eggs stick to leaves. This stage usually occur in late spring-summer.
2. Larval Stage.  Red Lily Beetle larvae consist of four larval instars, developmental stages between each moult within larval stage.  Larva are deep orange. The stage last about 10-11 days.  This stage usually occur summer.
3. Pupal Stage. After changing colour from yellow to orange, the pre-pupal larvae bury themselves in the soil and construct well camouflaged cocoon from which the beetle emerges as young adult after 20-22 days of pupation. This stage usually occur in summer-autumn.
4. Adult Stage. The adult over winter in the litter, reemerging in the spring from their hibernation sites and feeds on lilies and fritillaria. This stage usually occur in winter-spring.
