The female lady beetle lays 200 to 1000 eggs over several months during spring and early summer. [3] The eggs are small and spindle-shaped and are laid near the prey in upright batches of fifteen to thirty eggs. The larvae are dark and somewhat alligator-shaped. [3]
After hatching, the larvae will begin eating, including the other eggs in their clutch. [7] Certain species lay extra infertile trophic eggs with the fertile eggs, providing a backup food source for the larvae when they hatch. The ratio of infertile to fertile eggs increases with scarcity of food at the time of egg laying. [41]
The family Coccinellidae ("ladybirds", "lady beetles", or "lady bugs") is divided into seven subfamilies, many tribes, and about 360 genera: Subfamily Chilocorinae
In the few days leading up to the eggs hatching they begin to darken to a greyish colour. [14] Up to 30 eggs can be laid by a female per day, and as many as 1600 to 3800 in a lifetime. [ 4 ] Larvae hatch from the eggs by breaking the shell with sharp, circular structures on the back of their head called egg-busters. [ 13 ]
The eggs of the Phalacrotophhora quadrimaculata have been observed to be laid on the pupa of Olla v-nigrum and are usually placed in groups of up to 8 on their victims. Eggs are usually stuck on the host's cuticle either laterally or ventrally. Following the hatching of the eggs, the larva will penetrate and enter the host immediately.

Larva hatch from their eggs 4-6 weeks after being laid and develop into adults over the course of 3-4 years. Immediately after hatching, larvae will gnaw on small roots. It will continue feeding on roots, particularly grasses, cereals, and other crops, during its three larval stages, only pausing to burrow deep into the soil for winter hibernation.
