Study finds most female rhinoceros beetles mate once in lifetime

A study has found that most female Japanese rhinoceros beetles mate only once in their lifetime. This behavior is linked to their adult lifespan of a maximum of about two to three weeks in the wild, making mating a programmed once-in-a-lifetime event.

According to The Japan Times, a study by Yamaguchi University researchers has determined that most female rhinoceros beetles mate only once in their lifetime. The adult Japanese rhinoceros beetle has a maximum lifespan of about two to three weeks in the wild, leading to the belief that mating is programmed as a once-in-a-lifetime event. Keywords associated with the article include beetles, Yamaguchi University, INSECTS, and ANIMALS. The report was published on March 17, 2026, shedding light on insect reproductive strategies.

A parasitic ant species from Japan, Temnothorax kinomurai, has been confirmed to produce exclusively queens, with no males or workers. Researchers found that these queens reproduce asexually and invade colonies of related species to raise their offspring. This discovery reveals a novel form of social organization in ants.

An international study of mammals in zoos shows that limiting reproduction through contraception or sterilization increases average lifespan by about 10 percent. The effects differ between sexes, with males benefiting from reduced testosterone and females from avoiding pregnancy's physical toll. These findings highlight a key evolutionary trade-off between breeding and survival.

Scientists have confirmed that Belgica antarctica, the southernmost insect on Earth, is ingesting microplastics in the wild. Lab experiments reveal that while the insect's larvae survive short-term exposure, higher plastic levels lead to reduced fat reserves. The findings highlight the global reach of plastic pollution, even in isolated Antarctica.

A University of Cambridge study ranks humans among the most monogamous mammals, closer to beavers and meerkats than to chimpanzees. By analyzing sibling ratios across species and human societies, researchers found that long-term pair bonding is unusually prevalent in our species. Even in cultures allowing polygamy, human monogamy exceeds that of most other mammals.
