Life Cycle: Females lay curved rows of whitish eggs (20 to 70) on the underside edge of Pondweed leaves. They do not lay on lilies. Eggs hatch in about 10 days. 1st instar larvae create a moveable case made of 2 pieces of leaf; larvae remain on the underside of the leaf. Larvae are translucent whitish to grayish with a dark head and shield. New cases are made as larvae grow, and pupation takes place inside a case lined with silk and attached to a submerged stem. Adults attracted to lights, also day-flying.
