New York City is invaded by hordes of insects. After being hit three weeks ago by the smoke from forest fires in Canada, since last week swarms of aphids have been moving in Manhattan and Brooklyn and fueling psychosis.
For a week, the images have been surging on social networks. You can see impressive videos of thousands of white or green insects clinging to skin, hair and clothing.

Internet users do not hesitate to share their theories, sometimes a little eccentric, ranging from midges attracted by the smoke of Canadian fires, to divine punishment.
These hypotheses have been refuted by several scientists in the American press. The smoke would have no connection with the arrival of these insects.

According to the professor of entomology at Cornell University Corrie Moreau, it would be aphids which proliferated thanks to the mild and humid temperatures which have persisted since this winter.
Indeed, more flowers and plants have grown this year thanks to a mild winter and a rainy spring, which would have attracted insects, she explained in the New York Times.
If the researchers have so far failed to formally identify the species that is spreading, they want to be reassuring. Supported by the New York City Department of Health, they claim that these insects are not dangerous and that they could leave as quickly as they appeared.
