A new study has mounted perhaps the most intricate, detailed look ever at the diversity in structure and form of bees, offering new insights in a long-standing debate over how complex social behaviors arose in certain branches of bees’ evolutionary tree. The report offers strong evidence that complex social behavior developed just once in pollen-carrying bees, rather than twice or more, separately, in different evolutionary branches—but researchers say the case is far from closed.
Researchers at the University of Florida and the USDA-ARS have created a mobile app for bark beetle identification, allowing users to either play a beetle ID game or browse through the bewildering diversity of morphologies in the world of bark beetles.
Though studied for decades as a model organism, the tobacco hornworm's lack of silk production has never been thoroughly researched, until now. A team of researchers combining high-tech microscopic imaging with genomic techniques have captured in new detail the caterpillar's first instar silk-producing anatomy and subsequent loss of that capability as it molts to later instars.
A new collection of research spotlights emerging new technologies and research methods revolutionizing the study of morphology.
The fat lower legs that dangle below flying wasps in the family Gasteruptiidae turn out to be filled with insect fat body, and they may play key roles in flight dynamics, detecting vibrations from prey, and even detoxification.
