We demonstrated that the Z. maha population in the Fukushima area is deteriorating physiologically and genetically.
[We] conclude that the present outbreak of abnormal individuals in the Fukushima area was caused by random genetic mutations in addition to physiological effects due to the artificial radionuclides from the Fukushima Dai-ich NPP.
Our demonstration of heritable germ-line genetic damage caused by low-dose exposure due to radioactive contamination in a species of butterfly has invaluable implications for the possible future effects of radiation on animals. In view of the detection of plutonium released from the Fukushima Dai-ichi NPP44, the possible risk of internal exposure from ingestion should be investigated more accurately in the near future.
- Japan Researcher on Mutated Worms: “Almost all eggs of the container died maybe because of damage by alpha ray, however, the damage happened not to be fatal, so that there were some larvas still alive”

- Japan Times: Study finds 'abnormalities' in 52% of second generation offspring from butterflies collected May 2011 -- Unusually small wings, premature death
- Biologist on Mutated Butterflies: Study is overwhelming in its implications for humans -- Japan Researcher: Insects were believed to be very resistant to radiation -- Irregularly developed eyes, malformed antennae, much smaller wings (PHOTO)
- The Australian: The devastating physical & genetic effects of Japan's nuclear disaster are revealed -- All mutant butterflies were caught far outside Fukushima evacuation zone
