I guess this trap caught a bug that was a little too big again.
It’s the second time that an ulcer has formed on one of this plant’s traps after it caught a bug that was a little on the big side. I saw a TikTok video explaining that sometimes the trap will survive and it will just have a hole in the side, but I’m not holding out any hope for that. The last one just died. Fortunately,the rest of the plant seems healthy.
I think this isn’t great but it isn’t that bad. The plant still got to digest the bug for a while, so it got some energy back.
