Rare weevil with markedly long snout pictured on Yakushima Island+

(Japan Economic Newswire Via Thomson Dialog NewsEdge)NAZE, Japan, March 3_(Kyodo) _ The camellia weevil, a very rare type of weevil known for its markedly long snout, has been successfully photographed on Japan's southwestern Yakushima Island, according to a pair of experts.



Takaaki Nakata, 51, a resident park ranger on the Kagoshima Prefecture island, and his associate have photographed a camellia weevil actually perched on a camellia tree, which is a very rare sight, he said.

The weevil is known as "tsubakishigi zomushi" (camellia snipe weevil) in Japanese as it punctures the fruits of a camellia tree using a long snout, which resembles a snipe's beak, to lay eggs.



Last year, Nakata spotted a female camellia weevil on the island's western mountains when he visited the area with Isao Matoba, a curator at the Wakayama prefectural museum on natural history known for his study on weevils.

Nakata said the snout of the camellia weevil was more than twice as long as its body, which was shorter than 1 centimeter. He says the camellia weevil's snout is markedly long among about 800-900 types of weevils believed to exist in Japan.

The fruits of apple and camellia trees on the island are known for their large size, with some measuring 10 cm in diameter. Nakata and Matoba say the camellia weevil's snout may have grown longer as it adapted to the need to puncture thick-skinned fruits.

"There are reports that the size of fruits and the length of weevil's snout grow in tandem to each other," Matoba said.

"Weevils are still full of mysteries. I want to use the latest findings for the future study," he said.
