The diagrams illustrate a lady bird’s life cycle from egg to adult stage and the main anatomical features of the adult insect.
Overall, the life cycle of a ladybird involves four distinct stages, lasting from several days to weeks. Meanwhile, the anatomy diagram highlights its key external structures.
The life cycle begins when a female ladybird lays eggs on a leaf. This egg stage typically lasts two to five days. The eggs then hatch into larvae, which remain for about 21 days, feeding and growing rapidly. Following that, the insect enters the pupa stage, which lasts around seven days. During this phase, the ladybird undergoes internal and external transformation before emerging to adult.
The second diagram presents the anatomy of an adult ladybird. At the front is the head, including eyes and a pair of antennae. The pronotum are behind the eyes, meanwhile, the body includes an abdomen, legs, and wings. The most distinctive feature is the pair of red elytra with black dots scattered on them. Together, these anatomical structures enable the ladybird to feed, move and reproduce effectively.
