When you think of pollination, you often think of butterflies or bees flying around your garden. While these insects are important to flowers and our food supplies, new research shows just how much plants and crops rely on insects that fly at night for pollination.

Most flowering plants count on pollinators for reproduction. Recent years have seen a dramatic drop in pollinator populations. The factors behind the loss have been linked to habitat loss, pesticides and climate change. Research estimates 3-5% of fruit; nut and vegetable crop production is lost globally due to inadequate pollination.

A recent study at the University of Sussex, UK, discovered moths are more efficient pollinators than bees. The team studied both daytime and nocturnal pollinator visits. They discovered that 83% of all pollinator visits occur during the day.  Although only 17% of pollinator visits occur at night, the study also noted that moths were able to pollinate flowers more quickly than daytime insects.

The reason nocturnal moths are more efficient pollinators is that moths collect so much static electricity while in flight that pollen is pulled through the air to them. The researchers noted that moths do not need to touch flowers in order to pollinate them. The pollen is pulled across the air gaps as the moths fly several millimeters or even centimeters above.

The researchers concluded nocturnal pollination is understudied. As moths have been shown to transport pollen from a wide variety of plant species, further research is needed to fully appreciate the role they and other nocturnal insects play.

To understand just the important role moths play in pollination, the University of Sheffield, UK, found moths account for a third of all urban pollination. However, a lack of native plant species and diversity of plant life in cities, coupled with scent-stifling air pollution, is still leaving moths struggling to find their next meal.

And finally, experts are warning of an “alarming” global decline in moth population and diversity.


Differences between Butterflies and moths

Most butterflies are colorful and active during the day.  Most moths are active at night or during twilight hours and are generally more camouflaged than colorful.

Butterflies have “clubbed” antennae with thickened ends. Moths typically have feather-like or pointed antennae.

Most butterflies have thin, hairless bodies. Moths often have stout, hairy bodies.

Butterflies usually rest with their wings closed upright.  Moths mostly rest with their wings open or else fold them tent-like over their bodies.


To highlight the importance of moths as pollinators, TLCNP has held two evening moth roundups. Below is a list of nocturnal critters (moths, beetles and other insects) that were seen those evenings.

Dirt-colored Seed Bug

This is a common name for over 2,100 small bugs. These can be found in North, Central and South America.  They are very common in the Southern United States.  They can be easily identified by the white triangle in the middle of their wings.  They generally feed on seeds from a wide variety of plants. 

They are often called true bugs.  True Bugs are insects that have two pairs of wings, an outer pair and inner pair.  The outer wing covers are held over the back and often partly folded. True bugs have hypodermic-needle-like mouthparts that allow them to extract subsurface fluids from plants and animals. True Bugs undergo incomplete metamorphosis, with their young looking similar to adults, but without wings.  Seen at TLCNP in November 2024.
