This is included as part of the admission to the Jardin de Botanique. It is quite a small building filled with lots of information on everything that happens to insects with a few live ones to look at, and lots of dead ones. It is a bit interesting especially seeing some of the insects you would never get to see in real life but its not something I would race out to visit again unless I was bug obsessed. Kids seem to enjoy looking at all the bugs and the Ant Farm is pretty neat to watch but take the kids to a park and let them find some live bugs.
