A swarm of moths has invaded a small town in France, leaving its residents fed up with their uninvited guests.
The city of Oyonnax, in the department of Ain in eastern France, has hosted thousands of boxwood moths in recent weeks, according to a local.
In a shocking recording filmed on September 9, you can see a cloud of insects glued to a window and moving around a lampost.
Gaelle Lecompte recorded the swarm around 9:30 pm and says he was greeted by sight when he and his partner arrived at the village late at night.
Dozens of moths can be seen in the windowpane while swarms of thousands more fly under a lighthouse.
In the video surprised voices are heard, clearly surprised by the view from the outside.
Lecompte believes that the presence of insects is partly explained by streetlights.
He said: "Moths are particularly concentrated in our town, especially at night because of these streetlights."
A theory of why creatures can be attracted to light is because they use it to help migrate.

Some experts have argued that moonlight can give moths navigation clues and that artificial light could throw the moth's internal navigation system.
However, other experts do not believe in this theory and instead argue that moths are attracted to the infrared spectrum emitted by candlelight.
This is the same as the spectrum emitted by pheromones of the female moth that causes male moths to fly towards it.
The boxwood moth is native to Asia, but now it is found in Europe. It has been spreading in France since 2008.
