How do ladybugs reproduce?

Ladybugs mate by the male mounting the female of the species and deposit his sperm. The males are able to hang on to the females' hard wing coverings if the female tries to resist.

Ladybugs mate for several hours at a time without stopping. The female is able to store the sperm of the male for over 2 months. The mother chooses an ideal spot to lay her eggs, typically one that has many aphids to feed on, and lays her eggs on a leaf. Ladybugs are very promiscuous and have several sexual partners. Because of this, ladybugs have one of the highest rates of sexually transmitted diseases noted in a insect species. In London, 9 out of 10 of the ladybug population was seen to have a STD.
