The virus-carrying Asian tiger mosquitoes that have made headlines around the world are moving towards the UK.
According to French media, the tiger mosquitoes, which first appeared in France in the south-eastern city of Nice in 2004, have moved north over the years, sweeping across the country and reaching Paris in 2018.
Now new areas of the country are under threat from the mosquito, which can carry viruses such as dengue, chikungunya and Zika.
Over half of France is now in the red danger zone, which represents areas where the mosquito is "implanted" and "active".
It has now been revealed that 58 French departments are at risk, compared to just 51 last year.
Two maps show the spread of the virus-carrying mosquito (Aedes albopictus) in just the last few years, with the first, by French organisation Vigilance Moustique, showing the current extent of the mosquito's spread in France.
The second map, by the French government agency, the Institut de Veille Sanitaire (Health Watch Institute), shows the spread of the mosquito from 2004 to 2014. Back then, it was limited to the south-eastern corner of France, and the French island of Corsica.
Ibiza has also seen an invasion of Asian tiger mosquitoes which are reportedly four times bigger than normal.
Spain has been hit hard by coronavirus and the mass closure of hotels and holiday villas mean many swimming pools have been left untreated, providing the ideal breeding ground for the insects which thrive in moist air.
The department for environmental management in Ibiza's council has urged residents to purify their pools, saying leaving them untreated could lead to a "real public health problem".
The mosquitoes seem to be spreading north towards the UK. which is particularly worrying given the insects' preference for urban environments.
The dangerous mosquito is easily recognisable thanks to its black and white stripes. It tends to be active during the way and can bite through clothing.
It is not currently known to carry the coronavirus.
It's native to Southeast Asia but has spread to a large number of other countries by smuggling into transported goods.
