Insects and other bugs provide pollination at night – remember the moths – forest duff and other detritus breakdown, along with food for birds and bats, among other ways hat provide services to nature, ourselves included.  It’s long been noted that human use of night lights can disrupt and disorient bird migrations. Now research shows the insect population is also negatively affected.
What to do? Porch lights, yard lights, tall buildings lit up overnight? These are important for safe human functioning, personally, commercially. AND they can be tailored to protect other species with motion censors, automatic timing, Dark Night shades directing the lights downward. Cities such as Charlotte NC have ordinances to mitigate night time commercial usage of light. We can make similar choices in our homes, farms, industrial and commercial areas of towns, whether large or small. Dark night home light shades are available at local stores and online.

Climate change, pesticides and land use changes alone cannot fully explain the decline in insect populations in Germany. Scientists have now discovered that regions that have experienced a sharp decline in flying insects also have high levels of light pollution. Many studies already suggest that artificial light at night has negative impacts on insects, and scientists should pay greater attention to this factor when exploring the causes of insect population declines in the future.
