You have a leafhopper of some type. Being an inch long is not normal for the US or Canada. Since you found it in bananas, I would suggest you keep it in a glass jar so it can not get out to contaminate North America. Not that we grow many bananas in the northern regions, it is best not to let a forgein pest get established...as it may also like some of our local plants.
Leafhoppers feed on plant juices and can cause economic damage.
You might send it to one of your local agricultural offices (in the States we would send them to the extension service for an entomologist to check )...they could perhaps identify it and put it in a collection for educational purposes. I love to show children large insects and the larger ones come from the tropics.
Thanks for asking and keeping it contained!
