New large-sized insect species discovered in tropical forest

Scientists have studied the diversity of tropical parasitoid wasps for years. Parasitoid wasps are among the most species rich animal taxa on Earth, but their tropical diversity is still poorly known. Recently, the research group sampled Afrotropical rhyssine wasps, which are among the largest wasps.

Bumble bee workers sleep less while caring for young

All animals, including insects, need their sleep. Or do they? That's the question researchers are exploring in sleep studies of a surprising group of subjects: brood-tending bumble bee workers. Their studies show that worker bees tending pupae sleep much less than other bees do, even when caring for offspring that aren't their own.

CRISPRed fruit flies mimic monarch butterfly, and could make you vomit

Monarch butterflies and a few other insects evolved essentially the same genetic mutations allowing them to eat toxic milkweed without getting sick. Monarch butterflies and caterpillars store the toxins to deter predators. Scientists have now used CRISPR gene editing to make these same mutations in fruit flies, successfully conferring toxin resistance. This is the first time an animal has been genetically engineered to eat a new food and employ a new type of deterrence.
