新手求教, 我媽買了棵蝴蝶蘭...但.....

大家好, 昨天我媽買了棵蝴蝶蘭, 其實那花真的很漂亮的~~~


但我發現葉片有黃


而且是不是不夠水?好像不太光滑...


而且3片葉子裡一片斷掉, 一片裂開了


還有剛剛幫她抹葉子的時候, 看見有隻小昆蟲, 黑黑小小會飛的, 藏在那些泥土裡, 但我抓不到它, 有問題嗎?

請各位大大幫忙給些意見好嗎? 我還是第一次養蝴蝶蘭呢......

It doesn't matter. They are very strong, when they change environment the leaves grow yellow or a bit different, but they are ok when they get use to it.
stay dry and don't water too much.
