My 2 and 5 year bug-loving girls really enjoy this book! I love the facts inside and the real photographs of the bugs. I even learned some interesting facts about bugs that I did not know previously. My 5 year old was very excited about the activities at the end. Some of the activities were good for her age and some were simpler and probably geared toward 3-4 year olds but she still had fun. I highly recommend this book for any bug-loving kid!
