Eggs are laid in the early spring by adults that have overwintered. After larvae emerge and then pupate, like other Coccinellidae, adults live for a few weeks in the summer until the weather cools. The final generation overwinters as diapause occurs. Adults of cannot mate and reproduce until after emerging from diapause in the spring. Development of is temperature dependent, with beetles that develop at lower temperatures reaching a greater size. The time of development from egg to adult is also temperature dependent, taking about 14 days at 30 degrees Celsius, while taking up to 115 days at lower temperatures (10 degrees Celsius).

There is little information available on this topic for. The cream-spotted lady beetle can fly, and is mainly a solitary species.
There is no information available on this topic for, but other lady beetles are known to use visual and chemical cues for location of prey and mates.
psyllids and aphids. Feeding on psyllids seems to promote faster larval development, especially Cacopsylla mali. Six Aphididae species have been identified as essential food for : Chaitophorus tremulae, Cavariella konoi, Aphis farinosa, Eucalipterus tiliae, Euceraphis betulae, and Macrosiphoniella artemisiae. (Gordon, 1985; Kalushkov and Hodek, 2001)are insectivores and thrive on
Intraspecific and interspecific predation of the eggs of Harmonia axyridis is an invasive coccinellid that is known to eat the eggs of many other coccinellids. is well protected against the attack of Harmonia axyridis due to a compound that coats the outer surface of its eggs. The effect of this compound may be due to the abundance of hydrocarbons on the coating of the egg as well as the presence of alkenes. There are also patches of a red substance that coat the eggs, which is believed to be a type of acid. As a coccinellid, can likely reflex bleed, emitting toxins from joints in the exoskeleton when threatened. The different colorations and elytral patterns function as a warning sign to predators. (Gordon, 1985; Ware, et al., 2008)is common.

It can be prey to other species of Coccinellidae, including Harmonia axyridis. can also serve as host to Coccipolipus hippodamiae, a sexually transmitted mite.

having coloration that serves a protective function for the animal, usually used to refer to animals with colors that warn predators of their toxicity. For example: animals with bright red or yellow coloration are often toxic or distasteful.
having body symmetry such that the animal can be divided in one plane into two mirror-image halves. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria.

a period of time when growth or development is suspended in insects and other invertebrates, it can usually only be ended the appropriate environmental stimulus.
animals which must use heat acquired from the environment and behavioral adaptations to regulate body temperature

forest biomes are dominated by trees, otherwise forest biomes can vary widely in amount of precipitation and seasonality.
having a body temperature that fluctuates with that of the immediate environment; having no mechanism or a poorly developed mechanism for regulating internal body temperature.
the state that some animals enter during winter in which normal physiological processes are significantly reduced, thus lowering the animal's energy requirements. The act or condition of passing winter in a torpid or resting state, typically involving the abandonment of homoiothermy in mammals.
a distribution that more or less circles the Arctic, so occurring in both the Nearctic and Palearctic biogeographic regions.
Found in northern North America and northern Europe or Asia.
An animal that eats mainly insects or spiders.
fertilization takes place within the female's body
A large change in the shape or structure of an animal that happens as the animal grows. In insects, "incomplete metamorphosis" is when young animals are similar to adults and change gradually into the adult form, and "complete metamorphosis" is when there is a profound change between larval and adult forms. Butterflies have complete metamorphosis, grasshoppers have incomplete metamorphosis.
the area in which the animal is naturally found, the region in which it is endemic.
reproduction in which eggs are released by the female; development of offspring occurs outside the mother's body.
an animal which has a substance capable of killing, injuring, or impairing other animals through its chemical action (for example, the skin of poison dart frogs).
the kind of polygamy in which a female pairs with several males, each of which also pairs with several different females.
"many forms." A species is polymorphic if its individuals can be divided into two or more easily recognized groups, based on structure, color, or other similar characteristics. The term only applies when the distinct groups can be found in the same area; graded or clinal variation throughout the range of a species (e.g. a north-to-south decrease in size) is not polymorphism. Polymorphic characteristics may be inherited because the differences have a genetic basis, or they may be the result of environmental influences. We do not consider sexual differences (i.e. sexual dimorphism), seasonal changes (e.g. change in fur color), or age-related changes to be polymorphic. Polymorphism in a local population can be an adaptation to prevent density-dependent predation, where predators preferentially prey on the most common morph.

A terrestrial biome. Savannas are grasslands with scattered individual trees that do not form a closed canopy. Extensive savannas are found in parts of subtropical and tropical Africa and South America, and in Australia.
A grassland with scattered trees or scattered clumps of trees, a type of community intermediate between grassland and forest. See also Tropical savanna and grassland biome.
A terrestrial biome found in temperate latitudes (>23.5° N or S latitude). Vegetation is made up mostly of grasses, the height and species diversity of which depend largely on the amount of moisture available. Fire and grazing are important in the long-term maintenance of grasslands.
