Insect Migration: Trillions of Insects Take to the Skies

What is Insect Migration?

Insect migration is the seasonal movement of insects from one area to another. Insects migrate for a variety of reasons, including to find food, mates, or a more favorable climate.

How Many Insects Migrate?

A recent study found that approximately 3.5 trillion insects migrate over southern England each year. This is equivalent to 3,200 tons of biomass. The study also found that insect migration is not limited to southern England, but likely takes place all over the world.

Where Do Insects Migrate To?

Insects migrate to a variety of locations, depending on the species. Some insects, such as butterflies, migrate long distances, crossing oceans and continents. Other insects, such as aphids, migrate shorter distances, moving from one field to another.

Why Do Insects Migrate?

Insects migrate for a variety of reasons, including:

To find food: Insects migrate to areas where there is more food available. This is especially important for insects that feed on plants, as plants are not available in all areas during all seasons.
To find mates: Insects migrate to areas where there are more potential mates. This is especially important for insects that have a short lifespan, as they need to find a mate quickly in order to reproduce.
To find a more favorable climate: Insects migrate to areas with a more favorable climate. This is especially important for insects that are sensitive to temperature or humidity.

How Do Insects Migrate?

Insects migrate in a variety of ways, depending on the species. Some insects, such as butterflies, fly long distances. Other insects, such as aphids, are carried by the wind.

What is the Importance of Insect Migration?

Insect migration is important for a variety of reasons, including:

Pollination: Insects are important pollinators, and their migrations help to ensure that plants are pollinated.
Seed dispersal: Insects help to disperse seeds, which helps to ensure that plants can reproduce.
Nutrient cycling: Insects play a role in nutrient cycling, which helps to keep ecosystems healthy.

What are the Largest and Smallest Insect Migrations?

The largest insect migration is the migration of the monarch butterfly. Monarch butterflies migrate from North America to Mexico each year, a journey of over 2,000 miles. The smallest insect migration is the migration of the aphid. Aphids migrate from one field to another, a journey of only a few hundred yards.

What are the Most and Least Common Insects That Migrate?

The most common insects that migrate are butterflies, moths, and aphids. The least common insects that migrate are beetles and flies.
