I see they offer tickets for the museum and planetarium combined but do they offer a ticket with those and the butterflies?

Yes. They are all correct! And it is one of the coolest things I have ever seen! I've only ever been to one other butterfly exhibit thingy when I was little for school in Canada.... The one here at the strong tho is breathtaking, and they have all of the cacoon things as well as turtles and small ground birds! I'm sorry for babbling on and on, I sound like I work there. Lol its just such an amazing thing that we are so blessed to be able to go there and see these amazing creatures!

Yes
