 | Most modern-day groups of beetles have been around since the time of the dinosaurs and have been diversifying ever since. ...> Full Article |
 | A type of beetle that lives its entire life burrowing through stored grain has been found to lack full colour vision, and what's more the vision it does have breaks the rules. Most other insects have trichromatic vision -- they are sensitive to ultraviolet, blue and long wavelength light. Scientists now reveal that this beetle has lost photoreceptors that are sensitive to blue wavelengths. ...> Full Article |
 | It appears that chemical warfare has been around a lot longer than poison arrows, mustard gas or nerve weapons -- about 100 million years, give or take a little. ...> Full Article |
 | Female beetles mate to quench their thirst according to new research by a scientist from the University of Exeter's School of Biosciences. The males of some insect species, including certain types of beetles, moths and crickets, produce unusually large ejaculates, which in some cases can account for around 10% of their body weight. The study shows that dehydrated females can accept sexual invitations simply to get hold of the water in the seminal fluid. ...> Full Article |
 | With the aid of a $530,000, three-year National Science Foundation grant, Indiana University Bloomington biologist Armin Moczek will continue his research into the origin and diversification of beetle horns. Horned beetles are increasingly being recognized as a new model system in evolutionary and developmental biology, and this is the second NSF grant given to Moczek to further develop his study system. ...> Full Article |
 | Large jaws are efficient in crushing hard prey, whereas small jaws are functional in capturing elusive prey. Researchers have suggested that such trade-offs between "force" and "velocity" could cause evolutionary diversification of morphology in animals such as birds, fish, and salamanders. Junji Konuma and Satoshi Chiba of Tohoku University found that a new trade-off exists in animal feeding behavior. The team suggests that diversification of carabid beetles could be caused by a "force" and "fit" trade-off. ...> Full Article |
