Fruit Fly Study Offers Clues to Insect Survival in a Hotter, Drier World
Researchers found the pupa’s barrier is internal and made of hyper-long hydrocarbons, and dehydration nearly doubled without the key enzyme, they said.

Fruit fly study offers clues to insect survival in a hotter, drier world
Researchers at the Francis Crick Institute have identified a specialized lipid barrier in the fruit fly pupa that protects against dehydration in dry and hot environments. Their findings also expose the lipid barrier's limit, suggesting that insects in some regions of the world may struggle to adapt to climate change.
Hidden protection: Fruit fly dolls survive their conversion into an adult animal using a water-repellent layer on the inside of their shell. This consists of unusually long hydrocarbons, which are already produced and stored in the larvae stage. Genetic experiments now show how the molecules protect from drying out and why large heat and drought can nevertheless become life-threatening. London (England).

How heat and drought threaten fruit fly dehydration defences
Research finds that the fruit fly pupa has a specialised lipid barrier that protects against dehydration in dry and hot environments, but the barrier has a limit, suggesting insects in some regions of the world may struggle to adapt to climate change.
