Ladybugs leave a ton of eggs on garden plants, and the larvae hatch when the time comes right. You would want to know how to recognize ladybug larva if you are expecting some to hatch soon. This article will tell you all about them.
Ladybugs are beneficial insects that eat up plant pests and help farmers and gardeners grow their crops.
While they eat up tree bark, fungi, mildew, leaves, and other parts of plants, they only lay eggs on the leaves.
The eggs develop into larvae. These tiny critters have black bodies with bright markings and are easy to recognize if you know where to look.
This article focuses on the story of these little creatures – what they look like and the life stages they go through before becoming the adult ladybugs we all know and love.
What Do Ladybug Larvae Look Like?
A ladybug larva is about ½ inch long with an elongated and spiky body.
The newly hatched larva looks like a tiny alligator with its black body covered in red, yellow, and orange markings.
From a distance, most people might get intimidated seeing them. While the spikes on their back may scare some people, they are also the highlight of its body.
However, there is nothing to be afraid of since ladybugs in the larval stage are entirely harmless to humans.
They do not bite people or harm us in any way. They consume pests for several weeks until they reach the pupal stage.
A larva can eat dozens of aphids in a single day and is even more powerful in pest control than adults.
The larvae have six legs attached to both sides of the thorax. The abdomen has nine parts, the last being its tale.
Their heads are well-developed, and mandibles are strong enough to eat up garden pests and plants.
The larvae start eating the minute they come out of their egg. However, it takes a few weeks for the larvae to grow into adults after getting out of their cocoons.
How Long Do They Live as Larvae?
A typical ladybug lays thousands of eggs in the three-month time they have during spring.
The larval stage starts about four days after the eggs are laid, but factors like temperature and environment may increase or decrease the hatching period.
Sometimes it may go from seven days to even a month.
The larval stage starts the minute the organism comes out of the egg.
What Do Ladybug Eggs Look Like?
There are different species of ladybugs worldwide, so their eggs may look different. Most eggs are oval-shaped and about 0.04 inches in height but can be tinier.
They can be found in different colors, including pale yellow, orange-red, white, and more.
They are usually tightly clustered together on the undersides of leaves or flower pots. Most insect eggs are taller than they are wide, and ladybugs are no different.
A typical ladybug lays at least 10 to 50 eggs in a single plant and ensures that it is infested with soft-bodied insects like aphids or scale insects.
She also guards the plant and steers away predatory insects that may want to steal the larva’s food during this time.
Female ladybugs lay both fertilized and unfertilized eggs in the cluster. Even if the larvae cannot find aphids, they can easily feed on the infertile eggs to survive for a few days.
Four Stages of Larva Life Cycle
Ladybug larvae go through four main instar stages before they develop into an adult.
Once the larva is out, it is in its first instar. At this point, the nymph is restricted in its movements and spends most of its time acclimatizing and looking for food.
The next task of the larva is to find food. Thankfully, female ladybugs always lay their eggs on leaves where food is already abundant.
If by some accident, there is no food source – the larvae will die in one or two days.
If they get a good start, they might keep growing for three to four weeks before they reach the next stage.
In this first developmental stage, larvae need to grow in size and therefore have to eat a lot. This is why the larvae are such voracious predators.
In the second to the fourth stage, the larvae continue eating aphids, helping them metamorphose into pupae.
Remaining Life Cycle
The larval stage lasts for about 20 to 30 days, during which the larvae acclimatize to the environment, consume aphids, molts, and shed their skin to reach the next stage.
During this stage, the larvae eat up to 400 aphids, but if the food sources are scarce, they may eat infertile eggs or even each other.
After the 20-30 day period, larvae start to change. Their outer shell starts to become harder, and their movements become slower.
Pupal stage
If the larva has stopped moving and eating anything at all it has achieved the pupal stage.
It is quite a transformational stage that lasts for 3 to 12 days. At the end of this stage, the pupae shed their black and orange skin and what comes out is the adult ladybug.
Adult stage
At the end of the pupal stage, the ladybug’s shell is soft. But it takes only a few hours to harden before it gains its typical bright colors.
Once the shell is set and pigmented, the ladybird leaves the shell and moves out.
Frequently Asked Questions
What looks similar to ladybug larvae?
The larvae look like orange and black miniature alligators with spiky exoskeletons and an elongated abdomen.
There may be many caterpillars that might look similar to ladybug larvae, such as the Malacosoma disstria or the yellow-striped army moth.
What color are ladybug larvae?
Ladybug larvae have elongated bodies covered in black color. You can also find bright markings on the abdomen’s lateral side, like red, orange, or yellow.
From afar, they look like tiny black alligators against the green backdrop of their host plants and are quite easy to pick out.
Do ladybug larvae bite?
Ladybug larvae do not bite; they don’t have teeth or mouthparts to do it. They can easily eat lots of aphids during this time.
Asian ladybeetles that look like adult ladybugs can bite people. They are an invasive species that enter people’s homes during winter to seek warmth and shelter.
How do I get rid of bugs that look like ladybugs?
You can get rid of bugs by vacuuming, spraying white vinegar on the insects, setting up light traps since bugs are attracted to light, drowning them in soapy water, or using insecticides to kill them.
Wrap Up
Ladybug larvae are uniquely distinctive insects. They can be easily spotted against the green backdrop of the leaves they are sitting on, because of their black color.
They look like tiny alligators and have striking colors on their back such as white, pink and yellow. There are a few caterpillars that might look like them, but mostly they are very easy to identify.
