The Billywig is an insect native to Australia. It is around half an inch long and sapphire blue. It flies at high speeds by very quickly rotating its wings, which are attached at the top of its head. The bottom of its body has a long, thin sting.

While Newt Scamander was visiting New York City in 1926, one of the creatures that escaped from his NewtCase was the Billywig. Newt pretended it was a moth and left the poor defenseless Billywig to live its life in NYC. However, as Newt’s boat was departing from New York, the Billywig flew back to Newt’s care, presumably living happily ever after.

Xenophilius Lovegood was also known to appreciate the Billywig. He believed that Billywig wings “induce an elevated frame of mind” and used them in his recreation of Rowena Ravenclaw’s Diadem.


Those who have been stung by a Billywig suffer giddiness followed by levitation. Generations of young Australian witches and wizards have attempted to catch Billywigs and provoke them into stinging in order to enjoy these side effects, though too many stings may cause the victim to hover uncontrollably for days on end, and where there is a severe allergic reaction, permanent floating may ensue.
