The time to fly away with maturity/旅立ちの時

Finally the earliest 3 swallowtail butterflies flied to the sky at this morning.
Its said that generally swallowtails have only 7-10 days remained to live with wings after emergence,when they do their genetic work to maintain their species.
(ついに最も早い3匹のナミアゲハが、今朝飛び立ちました。一般的にアゲハ蝶が羽化後生きるのは7-10日間、その間に次に世代に種を継続するために生きる。)
