Speciation Mechanisms in Insects: Beetles in Japan and its Distributions
Because of the upcoming summer and fall, I started to meet many Japanese children (mostly boys) who spend hours catching and playing with insects, or mushi. So when I observed the Organisms of Japanese Islands floor in National Museum of Science and Technology, I expect to figure out what are the famous beetles in Japan.
Two of the most popular beetles in Japan are Prosopocoilus inclinatus and Allomyrina dichotoma. They are so popular that anyone would find them in every large discount store, pet shop (except for those dedicated to cats and dogs), or often in souvenir shops along the streets of sightseeing spots in the country during summer until fall.
There is definitely a kind of atmosphere in favor of insects in general compared to Occidental countries. In Japan it is nice and natural to enjoy the songs of crickets just like the chirps of birds. Suzumushi (Comoeogryllus japonicus) is another kind of insect often sold as pet. Collection (not breeding) of butterflies, long horn beetles, etc. is quite popular among entomologists and amateurs, too as in Occidental countries. Because of the climate, Japan is very rich in any kinds of insects in the first place.
Prosopocoilus inclinatus
Allomyrina dichotoma
Beetle species originated from Japan islands and its neighboring islands are:
l Prosopocoilus inclinatus inclinatus (distributed over 4 main islands of Japan)
l Prosopocoilus inclinatus kuchinoerabuensis (belongs to Kumage islands, Kagoshima prefecture)
l Prosopocoilus inclinatus mishimaiwoensis (belongs to Kumage islands, Kagoshima prefecture)
l Prosopocoilus dissimilis dissimilis (in Amami-Oshima and Kakerome-jima islands)
l Prosopocoilus dissimilis elegans (from Tokara islands, Kagoshima prefecture)
l Prosopocoilus dissimilis kumejimaensis (from Kumejima island of the Okinawa islands)
l Prosopocoilus dissimilis makinoi (from Tokuno-shima, Kagoshima prefecture)
l Prosopocoilus dissimilis okinawaensis (distributed in Okinawa-jima)
l Prosopocoilus dissimilis okinoerabuanus (from Okinoerabu-jima, Kagoshima prefecture)
l and many others.
Species originated from islands in Japan
And some examples of insects which are imported from outer islands are:
Ø Prosopocoilus motschulsky (fromTaiwan)
Ø Dynastes hercules (originated from central and south America)
Ø Chalcosoma atlas (distributed in Southeast Asia)
Ø Cheirotonus jansei ( from southern China and Vietnam)
Ø Cheirotonus peranacus (originated from Malaysia)
Ø Cheirotonus formosanus (from Taiwan)
Ø Euchirs longimanus (from Ambon island, Indonesia)
