Females who are not yet ready to mate, have recently mated, or are about to lay eggs, will reject the male. They first approach a female, watch, then examine, mount and attempt to mate. Males of Coccinella septempunctata do a five step courtship display. There is no information about the mating systems of Coccinella novemnotata, but there is research that describes the mating systems of the very similar Coccinella septempunctata. After one day, the elytra on the adult Coccinella novemnotata harden. After approximately seven more days, the larvae spend one day in a pre-pupal stage where they stop eating and seem very slow and inactive. It takes an average of four to five days for Coccinella novemnotata to reach its third-instar. The larvae undergo four stages called instars. Larvae hatch from eggs after approximately four days. These animals are found in the following types of habitatĬoccinella novemnotata has complete metamorphosis and goes through egg, larva, pupa, and adult life stages. novemnotata is highly likely to be living in national parks, though the reason for this is unknown. These beetles can also be found on a variety of other plants in wooded habitats, grasslands and suburban areas. ( Gordon, 1985 Harmon, et al., 2007 Hesler, et al., 2009)Ĭoccinella novemnotata is found on agricultural land and lives on crops such as alfalfa, clover, corn, cotton, potatoes and soybeans. Another survey in 1993 found no Coccinella novemnotata in thirteen Northeastern states, though a single beetle was found in 2006 in Virginia, the first to be spotted in 14 years in the eastern states. A survey in 2009 found only a few of these ladybird beetles in western and central United States. However, its range has significantly decreased in recent years, especially in the United States. It was found throughout the Nearctic region in the United States and southern Canada. Range length 4.7 to 7.0 mm 0.19 to 0.28 inĬoccinella novemnotata, the nine-spotted lady beetle, used to be one of the most common ladybird beetle species in its range.Eggs that will not hatch shrivel and become dark brown or black within 2 to 3 days. Coccinella novemnotata eggs are usually orange to bright yellow in color. The elytra have black spots that get smaller in size and in number until the back of the beetle. The front part of the pronotum (the section between the head and elytra) is also pale. Coccinella novemnotata has a broad head with a pale band between its eyes. They range in size (area of their elytra, which cover their wings) from 24.36 to 37.66 sq. They are red, oval-shaped and range from 4.7 to 7.0 mm. Coccinella novemnotata usually has nine spots, which gives it its name (novem- means nine in Latin), although there are spotless forms which may be confused with Coccinella johnsi.
