Finding of Spiky-Looking Orange and Black Bug (Get Rid)
The larvae of Multi-Colored Asian Lady Beetles look spiky orange and black.
Definition
Larvae: The immature free-living form of most invertebrates.Spiky Looking Orange and Black Bug
Look like
- The Asian lady beetle larva resembles a small spiny alligator with an orange-black body. It has two small rows and the back side has orange-to-reddish spots.
- The bug is very black with an orange square on its back.
- It has small spikes and looks like a mini scorpion without the tail, and has no wings.
- Lady beetle larvae are dark and alligator-like. They have six legs. They are spiny and black with bright spots.
Shape
The larvae are small, alligator-shaped, spiny black, orange, and yellow insects that feed voraciously on aphids and other insects too slow to get out of the way.
Size
Newly hatched It is approximately 0.125 (1/8) inches or 3.175 millimeters long and grows to about 0.5 (1/2) inches or 1.27 centimeters.
Found
Some people have reported – it is approximately 1 centimeter or 10 millimeters in length, found on vegetation in an open area within a woodland.
Grow Up
The Asian Lady Beetle larva undergoes molting before transitioning into a pupa. This pupa, typically found near an aphid colony, attaches itself to a leaf or another surface. Resembling the adult beetle in size and shape, the pupa features an orange color with distinctive black spots.
Lady Beetles
The Multi-Colored Asian Lady Beetle is also known as Harmonia axyridis. It is a common insect in the landscape and also in urban areas. It is a native and mostly found in Asia and relatively new to Michigan.
It’s often confused with plant pests. Like other many exotic species, it has adapted to climates and habitats in the US.
It is a highly beneficial predator of a variety of insect pests, especially aphids, in food crops, trees, and landscape plantings.
When Lady Beetles Introduced
This species was introduced by USDA scientists in the late 1970s and early 1980s to control insects.
This Asian species was introduced into California in 1916 and into the rest of the United States and parts of Canada from 1978 to 1982. They are also found in Georgia, Louisiana, Mississippi, Maryland, Connecticut, and Delaware.
Where Lady Beetles Lives
Ladybug’s beetle is originally from Asia such mostly found in Japan, China, and Siberia. The Ladybug is found throughout the US. They can be found in open habitats including gardens, and fields, and even at home.
Did you know?
- Only one lady beetle may eat as many as 5,000 aphids in its lifetime
- It has 0 to 20+ black spots
- More than 450 species of lady beetles are found in North America
- Each larva eats 200 to 300 aphids
- Ladybeetles may eat 1000+ aphids in its lifetimeLady Beetles Also Known As
Lady Beetles are also called by different names:
- Harmonia Axyridis
- Lady Beetles (Ladybeetles)
- Multi-Colored Asian Lady Beetles
- Asian Lady Beetles
- Ladybugs
- Ladybird
- Ladybird Beetles
- Coccinellidae
- Harmonia Bug
Definition
Coccinellidae: Coccinellidae is a widespread family of small beetles.
Multicolored
The term “multicolored” describes the varying colors exhibited by this species, which include shades of black, red, and orange.
Number of Colore Spots
- Red: Two red spots
- Black: Zero to 19 or 20 or more black spots
- Typically, these insects possess 10 black spots on their forewings, although variations exist with fewer spots, faded spots, or even an absence of spots.
Forewing and Body Color
- Ranges from yellow – to orange – to red
- Some have yellowish or orange forewings
- Some wings have entirely black with red spots
- There are some bright reddish-orange ladybeetles
- Lady beetles are usually red or orange with black markings
- Some ladybeetles are black, often with red markings
- Coccinellids display vibrant colors as a defense mechanism against potential predators. This strategy is effective because many predators associate the bright combination of orange and black with toxicity and an unpleasant taste.
- The most common pattern is the black “M” on a white plate just above the wings
- The color of its back elytra generally ranges from mustard yellow to bright red-orange. Black forms are found in some parts of the world
Definition
Elytra: Either of the front wings in beetles that cover and protect the hind wings.
Distinguishing Characteristics
Definition
Pronotum: The segment located on the insect's back, directly behind the head, is referred to as the pronotum. On Asian Lady Beetles, it is straw colored with 4 black spots that form a W-shape when viewed from the front or an M-shape when viewed from behind.
Is This Beetle A Pest?
Definition
Reflex Bleeding: Adults are aposematically colored and when attacked, will secrete alkaloid-laden blood from their leg joints. This behavior is known as reflex bleeding.
Aposematically Colored: meaning their color serves as a warning.The blood is bitter to the taste and can make your hands reek from handling
However,
If you live in a house, you probably appreciate the nuisance factor of these little beetles during October when they defy all our efforts to keep them out and off our walls.
Beneficial Insects
Lady beetles are the best-known beneficial insects. More than 450 species are found in North America. Some are native to the US and some are found in other countries.
Moreover, it’s a good thing to see them around because the adults and larvae are predatory, and eat insects like aphids.
What Does Ladybeetle Eat?
- They eat other insects. Every Lady Beetle requires to eat many aphids. So that they can lay eggs
- To grow the Lady beetle larvae may eat their weight in aphids every day
- Ladybeetles may eat 1000+ aphids in their lifetime
- Each larva eats 200 to 300 aphids as it grows
- If they don’t find prey, they eat each other or other beetle species
- The total number of aphids consumed through the larval stages varied from 90 to 370 aphids, and across all larval stages averaged 23.3 aphids consumed per day
- An adult Lady Beetle consumption typically ranges from 15 to 65 aphids each day
How Big Ladybeetles Are?
- Size is approximately 0.25 (1/4) inches or 6.35 millimeters long. Adult Lady Beetles size is about 0.39 inches or 1 centimeter long
- The adult is oval-shaped and about 0.25(¼) inches or 6.35 millimeters long and about 0.1875 (3/16) inches or 4.7625 millimeters wide
Habitat
Feed: During the spring and summer, Lady Beetles feed on aphids or scale insects which are pests in gardens, meadows, fields, orchards, and trees.
In the fall season, they sometimes gather on the sunny sides of houses and in garages or on porches. As the afternoons when cool off, some of these beetles make their way indoors. If squashed the beetles may stain fabric and painted surfaces.
Confuse with Lady Beetles vs Ladybugs vs Ladybird
Lady Beetle is more scientifically accurate. That’s because, in reality, Ladybugs aren’t bugs at all, they are Beetles.
Actually, all ladybugs are actually lady beetles, because ladybugs aren’t bugs at all.
Life Cycle
Life History
Life: Typically, adults live 30 to 90 days, but they can live up to three years.
Eggs: Females lay over 1600 eggs in the whole. Eggs are laid in small masses and kind of look similar to pale footballs.
Pupating: After hatch, the larvae go through four instars before pupating.
Larvae: Larvae are usually black or grey and have orange-red markings on the abdomen. Plus they usually have cool-looking spikes on their backs.
Impact on Human Body
Some people have reported receiving a mild nip/bite from beetles that have landed on them. There have been concerns that large numbers of beetles may possibly cause air quality problems indoors that could occur allergies or asthmatic reactions or both.
Suggestions and Recommendations for Residential
People show low tolerance to lady beetles inside the house. Humans like them in the garden but hate them inside.
Trouble occurs when populations increase, and large numbers of beetles enter buildings in the fall to hibernate. During unusually warm winter days and in early spring, the beetles wake up and crawl into areas of buildings inhabited by people.
We Don’t Recommend
Spraying Harmonia lady beetles.
Our Recommendations
- It is better to gently sweep them up and return them outdoors.
- If huge numbers of Ledybugs continue to invade a house, the possibility it means that the weatherstripping around the doors and windows needs repair.
- One encouraging aspect of multicolored Asian lady beetle biology is that they are victims of various predators and parasites so that a population may be locally abundant, but after a year or two, the number of Harmonia lady beetles drops off dramatically. Because it eats each other when they don’t get any other food.2
