Lady beetles, ladybugs, ladybird beetles, or whatever you can them, are one of the most beneficial insects in the garden. The process of getting to be an adult ladybug is somewhat convoluted and requires a four-stage life cycle process known as complete metamorphosis. Since you want to encourage ladybugs in the garden, it’s good to know what ladybug eggs look like as well as familiarize yourself with ladybug larvae identification so you don’t accidently do away with one.
Ladybug Egg Information
The first stage in becoming a ladybug is the egg stage, so let’s absorb a little ladybug egg information. Once the female has mated, she lays between 10 and 50 eggs on a plant that has plenty of food for her children to eat once hatched, usually a plant infested with aphids, scale, or mealybugs. Over the course of the spring and early summer, one female ladybug can lay up to 1,000 eggs.
Some scientists think that ladybugs lay both fertile and infertile eggs within the cluster. The supposition is that if food (aphids) is in limited supply, the young larvae can feed on the infertile eggs.
What do ladybug eggs look like? There are many different species of ladybug, and their eggs look slightly different. They may be pale yellow to almost white, to a bright orange red in color. They are always taller than they are wide and clustered tightly together. Some are so tiny you can barely make them out, but most are around 1 millimeter in height. They may be found on the undersides of leaves or even on flowerpots.
Ladybug Larvae Identification
You may have seen the larvae of ladybugs and either wondered what they were or assumed (incorrectly) that anything that looks like that has got to be a bad guy. It’s true that the larvae of ladybugs look rather fearsome. The best description is that they look like tiny alligators with elongated bodies and armored exoskeletons.
While they are completely harmless to you and your garden, ladybug larvae are voracious predators. A single larva can eat dozens of aphids per day and eat other soft-bodied garden pests as well such as scale, adelgids, mites, and other insect eggs. In an eating frenzy, they might even eat other ladybug eggs too.
When first hatched, the larva is in its first instar and feeds until it is too big for its exoskeleton, at which time it molts – and will usually molt a total of four times before pupating. When the larva is ready to pupate, it attaches itself to a leaf or other surface.
The larvae pupate and emerge as adults in between 3 and 12 days (depending upon the species and environmental variables) and thus, begins another cycle of ladybugs in the garden.
