Reducing light pollution is a straightforward yet effective strategy to safeguard the lives of nocturnal insects when Matariki brings longer nights.
According to Janice Lord and Connal McLean's research, approximately one-third of insects drawn to artificial lights perish by morning, frequently due to weariness.
The substantial effects of light pollution on insect populations-which are essential for pollination and biocontrol-are highlighted by this concerning statistic.

According to research, light pollution now affects around 23% of the planet's surface area, which is causing an insect population drop on a global scale.
Moths and beetles, among other nocturnal insects, are especially at risk. Artificial lights pique their interest, but before they can mate and deposit eggs, they may become exhausted and even die.
Their population survival, as well as the ecosystems they sustain through pollination and biocontrol, are severely impacted by this.
The Powers of Nighttime Insects
Even with these difficulties, nocturnal insects have amazing adaptations that help them survive and travel in low light.
With only the light from the stars and moon, their compound eyes, which are composed of millions of microscopic lenses, can capture the maximum amount of light and discern color and movement.
For example, moths' eyes are trained to detect motion, which aids in their ability to navigate and sense changes in their surroundings, though not as precisely as that of their daytime flying counterparts.
A Request for Action: Preserving Our Priceless Nighttime Insects
During Matariki, the Māori New Year celebrated by the Pleiades star cluster rising, it is a good idea to consider how our actions affect these nocturnal creatures.
We may contribute to the preservation of the delicate balance of nature and guarantee the survival of these priceless bugs by turning off our lights during the longer evenings of Matariki.
For instance, it interferes with many species' growth and reproductive cycles, which rely on natural light cues for reproduction. Mistimed breeding brought on by artificial lighting can alter population dynamics.
Excessive night lighting disturbs the sleep habits of animals whose circadian rhythms are linked to the day-night cycle, such as some bird species. This can hurt the animals' daily activities and health.
Furthermore, artificial lights have the potential to confuse nocturnal creatures that rely on natural light sources, such as the moon and stars, for navigation. This is especially dangerous for migratory birds since they can run into lights-out buildings and other structures while traveling.
Artificial lights also attract insects, which can wear them out and keep them from mating and laying eggs, which can lead to population decreases.
Light pollution has an impact on interactions between predators and prey as well. Local ecosystems may become unbalanced as a result of predators taking advantage of lit regions to target light-attracted prey species.
Furthermore, impacted species may see a decline in overall survival and reproduction rates, endangering biodiversity.
Sea turtles are one example in particular; their high death rate is caused by coastal illumination luring their hatchlings away from the protection of the ocean.
Artificial lights disrupt the evening breeding rituals of amphibians, including frogs and toads, which can lower the likelihood of successful reproduction. It is crucial to implement responsible lighting techniques to lessen these negative consequences.
To lessen the skyglow, this entails turning down outdoor lighting, utilizing motion sensors, and pointing lights downward.
The delicate balance of ecosystems and the variety of animals that live there can be preserved with the use of such efforts.
Nocturnal insects that dart around in the dark are an important part of our ecosystems, even if we might not give them much thought.
It's time to acknowledge their superpowers and take action to lessen light pollution's negative consequences. By doing this, we save not just these animals but also our planet's natural legacy for future generations.
