A York University doctoral student has identified 19 new species of sweat bees in Canada, including one found in downtown Toronto. The study provides valuable insights into bee diversity and the evolution of social behavior in insects.
Scientists at the Phyletic Museum of Jena University are using MicroCT imaging to analyze insect genital morphology. The research aims to shed light on the key-lock principle, which explains how male and female reproductive organs fit together, and instead reveals that it's a result of sexual selection.
A study found that insect feeding by a spruce gall adelgid caused large galls to form, inversely correlated with distance from buds. Chemical stimuli were determined to be the cause of gall formation.
