Asian Lady Beetle vs. Ladybug: What's the Difference?
Asian lady beetles and the insects commonly called ladybugs can look very similar, which makes it easy to confuse them. Technically, Asian lady beetles are members of the lady beetle family. When people compare Asian lady beetles with ladybugs, they are usually referring to the differences between the multicolored Asian lady beetle and other familiar lady beetle species.
The biggest concern for property owners is behavior. Many lady beetles spend their time outdoors feeding on aphids and other small insects. Asian lady beetles can also provide this benefit outdoors, but they frequently become nuisance pests in Wisconsin during fall because large numbers may gather on buildings and move indoors for the winter.
What Does an Asian Lady Beetle Look Like?
Asian lady beetles can vary significantly in appearance. They may be yellow, orange, or red, and some have numerous black spots while others have few or no visible spots. Adults are generally oval and dome-shaped.
One feature commonly associated with Asian lady beetles is a dark marking behind the head that can resemble an "M" or "W." Their wide range of colors and spot patterns means that counting spots alone is not always a dependable way to recognize them.
Do All Ladybugs Look the Same?
No. Wisconsin has several species of lady beetles, and each species can have its own pattern, size, and coloration. Some species have two spots, while others have seven, ten, thirteen, or different markings altogether.
Because appearance varies, homeowners may assume every orange or red beetle with spots is the same insect. Behavior can often provide another clue, particularly when dozens or hundreds of beetles begin gathering around a building during fall.
Why Are Asian Lady Beetles on My House?
Asian lady beetles begin looking for protected winter shelter when temperatures cool. In Wisconsin, this activity is especially noticeable during warm autumn days following periods of colder weather.
The beetles frequently gather on sunny exterior surfaces, particularly areas receiving afternoon sunlight. Windows, siding, rooflines, eaves, soffits, and other structural features may attract large groups before insects begin moving into small openings.
Why Are Asian Lady Beetles Getting Inside?
Small gaps around windows, doors, siding joints, vents, utility openings, and other exterior areas can provide access to concealed indoor spaces. Once beetles enter, they may remain behind walls or in attics during cold weather.
Warm indoor temperatures or sunlight can cause some beetles to become active during winter. Homeowners may then notice them crawling near windows or appearing in rooms even though outdoor temperatures are very cold.
Do Asian Lady Beetles Bite?
Asian lady beetles can occasionally nip or pinch exposed skin. They do not feed on people, but their behavior can make them more bothersome than many other lady beetle species when populations become large.
They can also release a yellow defensive liquid when disturbed. This substance has an unpleasant odor and may leave marks on walls, curtains, furniture, and other surfaces.
