Warning -- this book contains top-secret information about butterflies! Prepare to be shocked and grossed out by this hilarious and totally true picture book introduction to a fascinating insect.

Butterflies are beautiful and quiet and gentle and sparkly . . . but that's not the whole truth. Butterflies can be GROSS. And one butterfly in particular is here to let everyone know! Talking directly to the reader, a monarch butterfly reveals how its kind is so much more than what we think. Did you know some butterflies enjoy feasting on dead animals, rotten fruit, tears and even poop? Some butterflies are loud, like the Cracker butterfly. Some are stinky -- the smell scares predators away. Butterflies can be sneaky, like the ones who pretend to be ants to get free babysitting.

This hilarious and refreshing book with silly and sweet illustrations explores the science of butterflies and shows that these insects are not the stereotypically cutesy critters we often think they are -- they are fascinating, disgusting, complicated and amazing creatures.
