''Hippodamia convergens'', commonly known as the convergent lady beetle, is one of the most common lady beetles in North America and is found throughout the continent. Aphids form their main diet and they are used for the biological control of these pests. == Life cycle == The female lady beetle lays 200 to 300 eggs over several months during spring and early summer. 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.〔(Cornell University )〕 Once the larvae begin feeding, they grow quickly and moult four times over a period of up to a month. The pupal stage lasts about a week and mating takes place soon afterwards. If there is an abundant supply of aphids the female may start laying within about a week of mating, but if the supply is scanty, she may wait for up to nine months.
