以前亀岡で見つけた、アカネツボミフクレフシを京都でも見ることができました。毎年アカネが咲く河川敷を観察していたところ、いくつかのつぼみが虫えい化していることがわかりました。この中にはアカネツボミタマバエの小さな幼虫が部屋を作って住んでおり、住まいのまま地上に落ちてサナギとなり、来年成虫が誕生します。
This day I saw the Akane tsubomi fukurefushi on Katsura River, which I had previously found in Kameoka area several years ago. It is a kind of gall (abnormal plant growth formed by insects) , very small and unconspicuous. When I was observing the riverbed where Akane blooms every year, I found that some of the buds had been transformed into galls. In these buds, tiny larvae of the fly make room and live. When it is mature enough, the galls fall to the ground with larvae in them. They emerge as adult flies when time comes next year.
