Butterflies are insects mentioned briefly in the How to Train Your Dragon Book series.


Butterflies are a specialized group of insects belonging to the Order Lepidoptera. Like all insects, they have a three-pairs of legs and wings. Their wings, however, come in two pair and are generally quite large and wide compared to the body and also delicate and often intricately patterned. Butterfly wings may be colored to help with camouflage, mimcry - such as 'eye' spots, or to warn of being poisonous. Most butterflies are completely harmless to humans, however.

Butterflies are almost exclusively nectar drinkers and pollinators, playing a very important role in ecology. Conversely, butterfly larvae - called caterpillars - are often detrimental to plants, as they may eat the leaves.


In both the Book series and in real life, butterflies are the subject of art, literature, and folklore, due to their delicate beauty.

How to Twist a Dragon's Tale

Butterflies are mentioned as insects that live on Berk, especially around the Heather. However, they are gone in Book 5 due to an excessively hot summer and dragon-produced fires.

Where once heather grew and swayed in the wind, covered with butterflies and grasshoppers and buzzing nanodragons, now there was only ashy stubble, scarred across with white, stretching out across the whole of the slope.
