Ladybugs tend to lay their eggs where food is abundant. It's almost impossible for the average person to tell them apart. But here are some clues that might help. First, females are usually larger than males. Second, if you observe one ladybug riding atop another ladybug, they are in the process of mating. In a three-month period that commences in spring or early summer, a single female ladybug can produce more than 1, eggs.
Scientists believe ladybugs lay both fertile and infertile eggs in the cluster. When aphids are in limited supply, the newly hatched larvae will feed on the infertile eggs. In two to 10 days, ladybug larvae emerge from their eggs. Ladybug larvae look somewhat like tiny alligators, with elongated bodies and bumpy exoskeletons. In many species, the ladybug larvae are black with brightly colored spots or bands.
In the larval stage, ladybugs feed voraciously. In the two weeks it takes to become fully grown, a single larva can consume to aphids. Ladybug larvae don't discriminate when feeding and will sometimes eat ladybug eggs, too. The newly hatched larva is in its first instar, a developmental stage that occurs between molts. It feeds until it grows too big for its cuticle, or soft shell, and then it molts.
After molting, the larva is in the second instar. Ladybug larvae usually molt through four instars, or larval stages, before preparing to pupate. The larva attaches itself to a leaf or other surface when it is ready to pupate, or metamorphose, into its adult form. In its pupal stage, the ladybug is usually yellow or orange with black markings. The pupa remains still, attached to a leaf, throughout this stage.

A single ladybug can lay up to eggs. After a female lays her eggs, they hatch in two to 10 days. The eggs are yellow, oblong, and laid in clusters in an aphid colony so the larvae will have a food source as they emerge from their eggs.. The larvae look like tiny alligators, and are about one-quarter of an inch long and blackish with orange stripes.
Larvae eat and grow for another days before entering the pupal stage, which lasts seven to 15 days. Once it emerges from the pupal stage an adult ladybug will live for approximately one year. Adult ladybugs are four to seven millimeters long around one-quarter of an inch.
The ladybug anatomy consists of a head, two antenna, two eyes, a pronotum covering the thorax, an elytra the hard shell that covers their wings , six jointed legs, abdomen and wings these are so thin you can actually see through them. Interestingly, ladybugs beat their wings 85 times per second in order to fly.
When threatened a ladybug can draw its heads into its pronotum, like a turtle does, to protect itself. Ladybugs hibernate in the winter months and will not fly when temperatures fall below 55 0 F.
