I have spotted a bug, what is this bug? Will it eat my plant? Is there more? If this is an issue how do I fix it?

Please may I have some help?

Hello, is this outfit too much? Have I gone too far with the yellow?

Yellow’s my favourite colour but I’m not sure if I went too far with this outfit.

Hello is anyone able to tell me of there’s something wrong with my plant.

The first picture is from 5 days ago and all though his leaf had a giant blemish it seemed to be doing alright. But I just looked at him a second ago and I can see that the previous almost alright looking leaf has shrivelled and died. Is this natural or is there something wrong?
