[Movie File] Japanese Oakblue (Narathura japonica)

Japanese Oakblue (Narathura japonica) is found from northern Honshu to Okinawa. Outside Japan it is confined to Taiwan and Korea. Adult butterfly hibernates and sometimes is seen active even in winter when it is warm. Larva feeds on various oaks (Quercus spp.). Recently this species is found at the center of Tokyo because the foodplants are abundant in parks and streets.

Searching for "Romeo" in Panay, Philippines

Kitamura's collection (Nymphalidae in Philippines)

 

Searching for "Romeo" in Panay, Philippines

   The late Mr. KITAMURA Minoru (1937-2003) is a Japanese butterfly enthusiast who made a great contribution to the study on immature stages of many butterflies in Philippines. He worked as a civil engineer but spent most of his spare time on the study of butterflies.

   Recently small part of his collection was donated to RIEB (Research Institute of Evolutionary Biology) where our secretariat is housed.

   Here the author of this blog would like to introduce his collection to the memory of him. This collection contains chiefly Nymphalidae and Hesperiidae in Philippines. Almost all specimens were collected by himself or his native staffs. So the collecting data is precise.

   Among these precious specimens, Romeo's Assyrian (Terinos romeo) is one of the most remarkable specimens.

   This beautiful species was first described from Panay in 1984 by Schröder and Treadaway who are well-known Lepidopterists specialized in butterflies in Philippines. After the discovery, no additional record had been obtained until Mr. KITAMURA re-discovered this species in northern Panay.

    In 1993, KITAMURA visited Panay to join the baptismal service for his Philipino relative. Then he went into the jungle for searching butterflies as usual. There he found one strange-looking Nymphalid butterfly visiting the tree flower. He got it but could not identify it. After going back home in Manila and checked the book. Soon he shouted "Oh, this is ROMEO!!"

After this discovery, he has visited there many times to unveil the early stages of this butterfly. But he could not make it though he found the female of this species for the first time in the world.

   He suddenly passed away in 2003. He has unveiled the early stages of more than 200 butterfly species in Philippines. His unprecedant achievement greatly contributed to the book, "The Life Histories of Asian Butterflies" (Vol.1-2) by Igarashi and Fukuda.

   KITAMURA's abrupt death was definitely a great loss to the study of butterflies in Philippines.  

2012 Annual Meeting

2012 Annual Meeting

   On December 15, we had the annual meeting at the University of Tokyo. Same as the last time, we had plenty of presentations so it started from the morning time.

   This year Dr. KATO Yoshiomi (Emeritus professor of International Christian University) won HAYASHI Prize. He made a special presentation titled "My life to unravel the mystery of butterflies: How was Japanese population of “Eurema hecabe” diveded into two good species?"

   In the afternoon, the presentations on Zephyrus Hairstreaks are carried out by various speakers. This featured topic contains the latest information on this group from Japan, Korea, Taiwan, China, Bhutan and Myanmar. Among them, the final presentation made by Mr. Shizuya Hideo drew much attention. His presentation was on the newly discovered Zephyrus from W. Myanmar. He himself has been studying the butterfly fauna in Myanmar for almost 20 years. He has discovered many new and interesting species so far. Last June he found another striking new species from western Myanmar.

   This new species was described as Burmaozephyrus kothayaungi (gen. et sp. nov.). Definitely the most remarkable discovery in 2012!!

   After the presentation session, the party was held.
