Life Cycle of Cottonwood Leaf Beetle
Egg The egg stage marks the beginning of the cottonwood Leaf Beetle's life cycle. Usually laid in clusters, these eggs are small and may be colored to camouflage with the environment. Growth at this stage is minimal, but essential embryonic development occurs within.
Larva Upon hatching, the larva of the cottonwood Leaf Beetle emerges. At this stage, it is notably different in form from the adult, lacking wings and reproductive structures. The larva focuses primarily on feeding and growing, molting several times as it increases in size.
Pupal After reaching sufficient size, the larva transitions to the pupal stage. Enclosed within a protective casing, dramatic transformations occur. The cottonwood Leaf Beetle will reorganize its body structure, developing wings and adult appendages. Color and shape can change significantly during this stage.
Adult Emerging from the pupa, the adult cottonwood Leaf Beetle's development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction. Coloration and size are typically final at this stage.

Agricultural Pests

Cottonwood Leaf Beetle larvae feed voraciously on the leaves of aspen, willow, and poplar, causing defoliation. Initial damage may be mild, but severe infestations can lead to significant leaf loss, stunted growth, and increased susceptibility to diseases, affecting ecosystem balance and potentially impacting forestry industries.
