Flying insects become disorientated and trapped by artificial light

Flying insects are often seen gathering around artificial light sources, and slow-motion videos collected and analysed by researchers from Imperial College London have provided new insights into this behavior. The videos reveal that nocturnal insects become disorientated and trapped by the light, leading to their gathering in large numbers. This phenomenon has been observed for decades, but the reasons behind it have remained unclear until now.

The research conducted by Imperial College London sheds light on why insects are attracted to artificial light sources. The slow-motion videos show that the insects are disoriented by the light, causing them to fly in circles or hover around the source. This behavior makes them vulnerable to predators and increases their chances of getting trapped. The researchers believe that the insects mistake the artificial light for the moon or stars, which they use for navigation.

This new understanding of the behavior of nocturnal insects around artificial light sources could have important implications for both conservation and pest control. By better understanding why insects are attracted to light, scientists can develop strategies to minimize their exposure and reduce the negative impact on ecosystems. Additionally, this research could help in the development of more effective methods for pest control, as it provides insights into the behavior of insects that are attracted to light traps.
