New Beetle Species Found Right Outside University Lab
Researchers at Kyushu University made an unexpected discovery. They found a new ladybird beetle species just steps from their lab. The beetle lives on Japanese black pine trees. It is called Parastethorus pinicola. Despite decades of insect research in Japan, no one had noticed it before. As a result, this finding highlights how much biodiversity remains hidden.
Tiny but Important
The beetle measures only one millimeter long. That is smaller than a grain of sand. For this reason, most insect collectors ignore pine trees. However, PhD student Ryōta Seki decided to take a closer look. “That is where I found the new species,” he explains. The discovery led to the first major update in Japanese ladybird classification in 50 years. In addition, the team analyzed 1,700 specimens.
Why It Was Overlooked
Small black ladybirds are very hard to identify. They all look identical from the outside. Therefore, scientists must dissect them and examine reproductive organs under a microscope. Many past records contained misidentifications. The study also corrected a long-standing error. A species previously called Stethorus japonicus is actually the same as Stethorus siphonulus, found across Asia.
Hidden Biodiversity Everywhere
The team named another new species Stethorus takakoae after Seki’s grandmother. She encouraged his love for insects.“Even in a city or on a campus, unknown species live right beside us,” says Associate Professor Munetoshi Maruyama. These tiny insects support our ecosystems. His hope is that this discovery makes people curious about the fascinating world at their feet.
