フィールド日記

タブノキにタブノキハウラウスフシが見られました。名前の通り、タブノキの葉の裏面につくられる虫こぶで、中にはタブウスフシタマバエの幼虫が入っています。虫こぶの中で越冬した幼虫は、春に成虫となり、新しい葉に産卵します。


I found the insect galls called "Tabunoki-Haura-Usu-Fushi (タブノキハウラウスフシ)" on the leaves of the "Tabunoki (タブノキ)" tree. The name comes from the shape of the insect galls, reminding us of Japanese 'Usu (ウス)', and the place which the insect galls cling to. ("Haura (ハウラ)" means the back of leaves in Japanese.) The larva of the gall midge called "Tabu-Usu-Fushi-Tamabae (タブウスフシタマバエ)" live there. The larvae stay in the insect galls through the winter and become adults in the spring and lay the eggs on the new leaves.
