Nocturnal Pollinators and Artificial Light at Night

The journal article Lost in the Glow: How Light Pollution Disrupts Pollinator Behavior is a structured literature review of the behavioral, ecological, and pollination-related impacts of artificial light at night on nocturnal pollinators, published in the Asian Journal of Environment and Ecology.

"Artificial lighting acts simultaneously as both a trap and a barrier for these insects attracting them toward illuminated zones while simultaneously fragmenting their natural habitats. This behavioural disorientation leads to decreased foraging efficiency, energy depletion, and elevated mortality, as individuals are often captured by predators or perish from exhaustion after circling lights for prolonged periods."

"White and green lights are most disruptive, leading to up to 62% declines in nocturnal visits" (Das et al., 2025)

"Red light proved to be least disruptive to pollinator behavior." (Das et al., 2025)

"The reduction in nocturnal insect abundance and diversity weakens the foundational level of food webs, as these insects serve as a critical food source for higher trophic groups such as bats, night-active birds, spiders, and amphibians. Consequently, diminished insect populations translate into reduced prey availability, forcing predators to alter their feeding behaviour or shift their foraging ranges, which can in turn lead to further ecological imbalances and energetic inefficiencies within the ecosystem." (Das et al., 2025)

This article gave me a broader perspective on how vital the nighttime ecosystem is to human survival. Reducing light at night is a small price to pay for a healthy ecosystem.
