Fruit flies medicate their larvae with alcohol
(Phys.org)—A new study in the U.S. shows that fruit flies lay their eggs on a food source with a high alcohol content if they see parasitic wasps in the area, instead of a non-alcohol food.

Even embryos can become embroiled in an evolutionary arms race with another species. Leiden biologists demonstrate this with larvae of the rosy bitterling that parasitize the gills of freshwater mussels. They published their ...
