Just wanted to know if this is something normal I should expect and should the caterpillar be removed. plant has done really well since I got it back in March. We got it as a mature /adult plant site said 5 years old. First pitchers are starting to turn brown now and this week I noticed a caterpillar had been eating some of the flowers leaves and now it's made it's way to one of the plants eating part of the lid and then at into the pitcher about halfway down. Is this a parasitic relationship or it it ok since the pitches had already started developing brown spots(I presume it's the pitcher being at the end of it's life). Any ideas from y'all?
