The June Bug was an American "pioneer era" biplane built by the Aerial Experiment Association (A.E.A) in 1908 and flown by Glenn Hammond Curtiss.

In 1907, Glenn Curtiss and the Aerial Experiment Association began building the June Bug with hopes of winning the Scientific American Cup.

The original varnish sealing the wing fabric cracked in the heat, so a mixture of turpentine, paraffin, and gasoline was used on the aircraft instead.

The aircraft was named by Alexander Graham Bell after the common Phyllophaga,[1] a beetle known colloquially in North America as the "June bug".

Orville wrote to decline the opportunity on June 30, as the Wrights were busy completing their deal with the United States government.

The Kalem Company's film crew covered the event, making the June Bug the first airplane in the United States to perform in a movie.

's aircraft used a wing-warping system like the Wrights' for control, relying instead on triangular ailerons designed by Alexander Graham Bell, which he successfully patented in December 1911.
