One-year-old larvae hatch from eggs, feed on decaying leaves, molt repeatedly, and become terminal instar
larvae ten times their size or more, which survive the winter. The life span of a beetle is about one year,
with about 9 to 10 months being the larval period. The beetle's newly laid eggs are white and soft, and
after a few days they turn brown and grow hard and large.
Beetle larvae have also been found to possess an antimicrobial protein called “kabutom defensin,” and
research into its application in the medical field is underway.
Overall, there is little difference in contrast, but material with particularly high CT values is found
around the anus. This is the same trend observed with other organisms such as newts and cicadas, and is
expected to be excretory material. Also, from the nine pairs of respiratory organs on the sides of the body,
we can observe branching tubes extending out from the respiratory organs.
