Niewiarowski et al., PLoS ONE 3, e2192 (2008) This tiny and colourful beetle is a natural predator of soft-bodied pests such as aphids, fruit flies, white flies and, less commonly, silverfish, and so is welcomed by most gardeners. Beutel, Naturwissenschaften 88, 530 (2001). The homeopathic remedy, Coccinella septempunctata (or, just Coccinella for short), is prepared from the ladybug or ladybird beetle. Gorb, Attachment Devices of Insect Cuticle (Kluwer Academic Publishers, Dordrecht, 2001) These findings demonstrate that humidity similarly affects the function of both dry and wet adhesive pads, although both types of adhesive systems (wet and dry) are supposed to be based on different physical interactions (capillarity versus van der Waals forces). This relationship was found both in female and male beetles, despite of a deviating structure of adhesive setae and a significant difference in forces between sexes. At 60% humidity, the highest attachment forces were revealed. At both low (15%) and high (99%) relative humidity a decrease of attachment ability was found. Thousands of new, high-quality pictures added every day. Our results indicate an optimal range of relative humidity with maximal traction forces.

In the present study, we therefore studied the attachment ability of the seven-spotted ladybird beetle ( Coccinella septempunctata) at different humidities by traction force experiments. For insects, however, the influence of the environment on attachment ability is lacking. Show algorithmically generated translations. Coccinella septempunctata est une espèce multivoltine en Grèce. Young larvae of the seven-spot ladybird usually also consume smaller prey by biting them and then sucking them dry. The freshly hatched Coccinella septempunctata larvae are very hungry and, depending on the aphid species, eat up to 1200 aphids during their development period, while adult seven-spot ladybirds only eat up to 150 aphids per day. Conditions such as ambient temperature and humidity have been shown to influence the attachment ability of the dry adhesive foot pads in spiders and geckos. Coccinella septempunctata (Coleoptera: Coccinellidae) in Greece is a multivoltine species. Seven-spot ladybirds purposefully lay their eggs on plants that are already infested with aphids. Many insects possess hairy adhesive foot pads, supplemented with a tarsal secretion, which allow them to securely and reversibly attach to various kinds of natural substrates, also under complex environmental conditions.
