The Taj Mahal in India is turning green due to insect poo.
Swarms of small insects are using India’s top tourist attraction as a toilet.
The problem’s been caused by insects breeding in a nearby polluted river – and there’s been a rise in the numbers of them.
Cleaners have been hired to scrub the Taj Mahal’s walls every day, but there are worries that their elbow grease could ruin the beautiful marble and mosaics.
The insects are a type of fly that look like a mosquito.
The Taj Mahal is actually a huge tomb built by Mughal Emperor Shah Jahan for his wife in the 1600s.
It is visited by millions of people every year.
