Record-breaking discovery of 99-million-year-old fossil
Larva of new species (Gondwana Research (2026))
The world's oldest known mosquito larva, dating back 99 million years to the Cretaceous era, has been discovered preserved in amber from Myanmar.
Named Cretosabethes primaevus, this fossil is the first mosquito larva found in amber from this period, offering new insights into insect evolution.
Unlike previously found mosquito fossils from the same era, this larva closely resembles modern species, suggesting that extinct and contemporary forms coexisted.
Scientists described its preservation as a "rare stroke of luck," as it required tree resin to fall precisely into a small body of water to encase the aquatic larva.
The discovery indicates that mosquitoes had already diversified by the Jurassic period, with their larval morphology remaining remarkably consistent for almost 100 million years.
