Life Cycle of Water ladybird
Egg The eggs are laid in clusters, typically on the underside of leaves. They are oval and can vary in color depending on the species, often pale yellow or orange.
Larva The larvae emerge from the eggs, resembling small caterpillars. They're voracious eaters, growing rapidly; their size, color, and patterns change with each molt.
Pupal After reaching a certain size, the larvae anchor to a substrate and form a pupa. The pupa may be attached to the underside of a leaf and will undergo significant transformation inside.
Adult Emerging from the pupa, the adult water ladybird'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.

Aphids, Scale Insects, Whiteflies
Water ladybird functions as a natural regulator of aphids, scale insects, and whiteflies. It uses its sharp mandibles to catch and eat pests during both its larval and adult stages. The predation primarily serves to satisfy its hunger and to nourish its offspring. An interesting fact about water ladybird is its voracious appetite during the larval stage, which helps significantly reduce the population of garden pests.
