Chinese researchers studied adult and larval Loricera specimens trapped in the Cretaceous in three amber fossils unearthed from the Hukawng Valley in northern Myanmar.
66 million years ago, a cataclysmic event shook the Earth. A massive asteroid impact led to the extinction of diverse life forms from the planet, including the mighty dinosaurs. But amidst the chaos, one tiny creature survived: a black beetle. genus, has defied the test of time. Recent studies have revealed a surprising fact that this species has remained largely the same for over 100 million years.
Darwin proposed that individuals within a population exhibit variation in their traits. Those with traits better suited to their environment are more likely to survive, reproduce, and pass on their advantageous traits to the next generation.Loricera beetles, both as adults and larvae, are specifically adapted to prey on springtails in leaf litter. To capture these tiny, agile insects, they have evolved a unique hunting strategy.
Analysis of ancient beetles revealed nearly identical antennal setae arrangements compared to modern species. The findings suggest that the insect’s physical form, overall size, and dietary preferences had not undergone any significant alterations despite experiencing major changes in its habitat and a major extinction event.
