They identified a specialised internal lipid barrier composed of hyper-long hydrocarbons synthesised in advance by larval cells.&nbsp;
This hydrophobic shield prevents lethal water loss in arid environments. However, testing revealed strict thermal thresholds where lacking the key synthesising enzyme doubles dehydration rates.&nbsp;
This discovery offers important clues regarding insect survival and climate change adaptation in a warming world.
