New York City residents were taken aback by an unexpected phenomenon in recent days as swarms of flying insects invaded various neighborhoods. The city, already grappling with smoke and haze from Canadian wildfires, now faced an additional nuisance in the form of these tiny critters. As residents wondered about their origin and potential impact, experts identified them as winged aphids, dispelling initial assumptions that they were gnats. While the swarms remain a fascination for some and an annoyance for others, bug experts reassure the public that there is no cause for alarm.

The Invasion and Reactions:

Martin DuPain, a Queens resident, discovered the flying critters after returning home from a walk. Covered in insects, he realized they were not wind-driven ash but actual bugs. Numerous reports and videos circulated on social media, capturing the scenes of people waving away the insects or taking precautions by covering their mouths and noses. While some neighborhoods experienced these swarms, others remained unaffected.

Understanding the Aphid Invasion:

According to Professor David Lohman, an entomologist at the City University of New York, the insects were identified as aphids based on visual evidence shared on social media. Aphids, small pear-shaped insects found throughout the United States, typically emerge after summer in New York City. However, the current swarms are unusual, likely triggered by warm winter temperatures disrupting the aphids’ biological clock. Experts theorize that the wildfires in Canada and extreme temperatures could also be influencing their behavior and abundance.

Insights from Aphid Experts:

Aphid specialists Natalie Hernandez and Andy Jensen supported the theory that the swarms may be a result of aphids producing winged morphs to disperse when their colonies become too large or dense. Additionally, the presence of smoke might be enabling the aphids to persist longer into the summer season than usual. While the exact cause of this phenomenon remains uncertain, it is clear that multiple factors may be contributing to the increased aphid activity.

Reassurances from Public Health Authorities:

The New York City Public Health Department issued a statement to alleviate concerns, stating that although the insect swarms may be annoying, they do not pose a known public health risk. The department is actively investigating the situation and will share any important health information with the public.

The Swarms’ Duration and Environmental Significance:

Bug experts anticipate that the swarms will likely dissipate soon, providing relief to residents. Despite the inconvenience they cause, the presence of numerous aphids is seen as a positive sign by entomologist David Lohman, who views it as an indication of New York City’s organic nature. He suggests that the abundance of aphids demonstrates a lack of widespread pesticide use in the city.


New York City’s recent invasion of swarms consisting of winged aphids has generated curiosity and annoyance among residents. While the cause of this unusual phenomenon is still being investigated, experts attribute it to factors such as warm winter temperatures and environmental disturbances caused by Canadian wildfires. Public health authorities assure the public that the swarms do not pose any known health risks. As the aphid populations naturally disperse, New Yorkers can look forward to the end of this intriguing yet bothersome encounter with these tiny flying insects.
