Coccinella novemnotata, the nine-spotted ladybug or nine-spotted lady beetle or C9, is a species of ladybug in the family Coccinellidae native to North America. This beetle was once ubiquitous across the continent but it experienced a sharp and drastic decline around the 1960’s. As a rare species, the nine-spotted ladybug has received much attention from researchers who wish to understand the causes of its decline and restore the population of this charismatic beetle to benefit from their aphidophagous nature as biocontrol agents in agriculture.
Pine and fir trees, grown purposely for use as Christmas trees, are vulnerable to a wide variety of pests, weeds and diseases. Many of the conifer species cultivated face infestations and death from such pests as the balsam woolly adelgid and other adelgids. Aphids are another common insect pest. Christmas trees are also vulnerable to fungal pathogens and their resultant illnesses such as root rot, and, in the U.S. state of California, sudden oak death. Douglas-fir trees in particular are vulnerable to infections from plant pathogens such as R. pseudotsugae.
Coccinellidae is a widespread family of small beetles. They are commonly known as ladybugs in North America and ladybirds in the United Kingdom; "lady" refers to mother Mary. Entomologists use the names ladybird beetles or lady beetles to avoid confusion with true bugs. The more than 6,000 described species have a global distribution and are found in a variety of habitats. They are oval beetles with a domed back and flat underside. Many of the species have conspicuous aposematic (warning) colours and patterns, such as red with black spots, that warn potential predators that they taste bad.
Coleomegilla maculata, commonly known as the spotted lady beetle, pink spotted lady beetle or twelve-spotted lady beetle, is a large coccinellid beetle native to North America. The adults and larvae feed primarily on aphids and the species has been used as a biological control agent. Based on name connotation and to avoid confusion with other species also called "spotted ladybeetle", spotted pink ladybeetle is probably the most appropriate common name for this species.
Exochomus quadripustulatus, common name pine ladybird or pine lady beetle, is a species of beetle of the family Coccinellidae. The distribution range of E. quadripustulatus includes Europe, Northern Asia, and North America.

The distribution range of Olla v-nigrum includes Central America, North America, and Oceania. It is usually gray or pale tan with small black spots on its elytra and thorax. However, a variation can resemble Chilocorus orbus, another species of lady beetle. This form is black with two red spots on the wing covers and has white on the edge of the prothorax.
