For the past one week, I have watched an anime series “TERRAFORMARS
.” The story is about cockroach extermination at Mars around 2600CE. In the story, scientists attempted to colonize Mars by spreading a modified algae and cockroaches for purifying the atmosphere and absorbing sunlight.
The most horrible point of it is that cockroaches have evolved from an insect form into a form like a Homo erectus to survive in Mars’s harsh environment. They have the incredible physical strength and are called “Terraformars.” On Mars, humans and cockroaches breaks out the war for survival.
The most attractive point is that heroes have various abilities respectively. To fight horrible cockroaches, they undergo genetic modification to inherit the characteristics of other organisms by having a special organ implanted.
One of the heroes, Hizamaru Akari, who has the skill of bagworm, can combat cockroaches by not only martial arts but also thin incredibly strong and elastic strings.
After watching the anime, I was interested in bagworms. Although we cannot see any bagworms recently, I could see some bagworms on the trees when I was young. I tried to find out the reason why bagworms disappeared.
The result from my netsearch, I can find some interesting facts.
First, the bagworm has specific features. Most common bagworm specie’s zoological name is Eumeta japonica. The larvae construct cases out of environmental materials such as plant materials. These cases are attached to rocks, trees or fences. Japanese call them Minomushi
. The adult males of most species are strong fliers with well-developed wings. On the other hand, the adult females lack wings.
Second, the bagworm has fear of extinction in west Japan because a species of parasitic fly has invaded from China 1990s. The fly’s name is Nealsomyia rufella. According to the file
, the density of the bagworm has extremely decreased because of parasitism by invaded fly.
