Asian Ladybug
As their name implies, these ladybugs originally hail from Asia, but now take wing throughout the Americas. They comprise one of the larger species of ladybugs, often growing beyond the common ladybug size of ¼ inch. Asian ladybugs display a variety of red and orange shades, which gives them the nickname "multicolored ladybug." Their black spots often form a pattern over their wings, in either two lines, or even fusing together into a larger black shape. Sometimes these ladybugs appear to have no spots.
Convergent Ladybug
Convergent ladybugs are the kind most often found for sale in gardening shops. They are sold to control garden pests, such as aphids. These ladybugs are more oval shaped, as opposed to round or dome shaped. They are also a truer orange color, and their black spots vary in number and pattern.
Seven-spotted Ladybug
These ladybugs, which are very common in the Americas, originally came from Europe. They are the traditional red color normally associated with ladybugs and, as their name implies, they have seven black spots over the red part of their round bodies, which is their wings. Seven-spotted ladybugs are often the first ladybugs to come out in the spring.
Two-spotted Ladybug
Two-spotted ladybugs are native to North America but also live in Europe. Like their convergent cousins, they are often sold to gardeners. The two-spotted ladybug is bright red with two parallel black spots on its back, one spot on either wing.
Pink Spotted Ladybug
Pink spotted ladybugs are among the smallest -- often less than ¼ inch long -- and therefore quickest ladybug types. Because they are so quick, they are effective pest reducers, able to catch a large amount of prey in a short period of time. As opposed to being traditionally red in color, these ladybugs are a lighter pink, and have an elongated shape.
