とんぼをおいかけて・・ ～♪～

２年ぶりかな、ヒヌマイトトンボのヤゴ調査に参加しました。For the first time in probably two years, I again took part in a field research on larvae of Mortonagrion hirosei Asahina.



尾鰓はちゃんと３本ありますが、たぶん２本は一回切れて再生したから、短いのだろうとのことでした。かわゆい子です！　It properly has three anal gills but two of them are short probably because they re-grew after being chopped off once. Isn't he (or may be she) cute?
