The reason why rhinoceros beetles are active at night ”It may be because there are bees during the day”
山口大学の小島渉先生は今年8月、山口市の林でカブトムシを調べました
Professor Wataru Kojima of Yamaguchi University examined beetles in the forests of Yamaguchi City in August this year.
However, later a bee called a giant hornet came and bit the beetle’s leg.
The bee sucked the sap after dropping the beetle from the tree.
When the bees disappeared, more than half of the beetles sucked the sap until noon.
Professor Kojima said, ”I thought it was the nature of rhinoceros beetles to be active at night.
However, there are bees during the day, so the time they are active may have changed.
