Developmental cost of leg-regenerated Coccinella septempunctata (Coleoptera: Coccinellidae). [PDF]
PLoS One, 2019 As larval cannibalism is common under intensive rearing conditions, leg regeneration can help ladybugs adapt to the competitive environment, but whether the leg regeneration leads to side effects on development remains unclear. To analyze the potentially developmental cost of leg regeneration, the developmental period and weight of leg-regenerated ...

Long term changes in abundance of Coccinella septempunctata (Coleoptera: Coccinellidae) in the Czech Republic [PDF]
European Journal of Entomology, 2005 Since 1978, the abundance of Coccinella septempunctata L. has been recorded at a hibernation site in the western Czech Republic. Over the years, abundance varied by two orders of magnitude and a long-term trend for decrease in C. septempunctata abundance

Olfactory orientation of the seven-spot ladybird beetle, Coccinella septempunctata (Coleoptera: Coccinellidae): Attraction of adults to plants and conspecific females [PDF]
European Journal of Entomology, 2000 The olfactory orientation of the aphidophagous ladybird Coccinella septempunctata L. was assessed in a Y-tube olfactometer and a choice arena. The response of the predator to 22 plants, aphid prey and conspecifics was tested.

Nutritive cost of intraguild predation on eggs of Coccinella septempunctata and Adalia bipunctata (Coleoptera: Coccinellidae) [PDF]
European Journal of Entomology, 2000 Coccinella septempunctata was approximately 20% more reluctant to eat the eggs of Adalia bipunctata than the reverse. In addition, fourth instar larvae of C. septempunctata failed to complete their development on a diet of A. bipunctata eggs and only 30%

Egg Predation by the Introduced Lady Beetle, Coccinella septempunctata (Coleoptera: Coccinellidae), Lowers Mortality but Raises Relative Risk for the Native Lady Beetle, Coccinella novemnotata. [PDF]
PLoS ONE, 2015 Populations of the native ninespotted lady beetle, Coccinella novemnotata Herbst, have undergone precipitous declines in North America following the establishment of the exotic sevenspotted lady beetle, Coccinella septempunctata L.

Sexual Dimorphism of Tarsal Attachment Devices and Their Relation to Mating in Coccinellidae. [PDF]
J MorpholWe explore the coevolution of male attachment devices and female elytral morphology in coccinellids. Specifically: (1) Disco‐setae are present in males of some species, located on the hairy pad which during mating hold on female elytra. (2) The area of male disco‐setae is extended when females have smooth elytra, and reduced when females have hairy ...
