Greetings hulabullu, Thanks so much for writing your review! Some of our guests find the free-flying butterflies a little bit startling but there really is nothing to be scared about - they can't bite or sting or hurt you in any way. Our staff are always available to help our guests that might be feeling a little frightened - sometimes it's easier to adjust when a staff member is there to answer your questions. We're thrilled to hear that you found our exhibits to be educational. We've just introduced twelve new terrariums that feature our tropical insect collection, we're very excited to be able to show them off! Thanks again for leaving your review, and we hope to have you back again soon!
