When we think of migration, we typically think about birds that are desperately escaping bad weather or eagerly seeking good weather.
Although we as humans cannot see this migration the words we can see birds soaring through the sky, a recent study that was published in the journal “Science” revealed that over three trillion insects migrate to south-central England each year.
Massive amounts of insects migrate for the same reason that massive amount of birds migrate: to seek warmer weather when the climates changes.
If human could see this migration, it would be alarming and appear almost an infestation. Entomologist at the University of Exeter, Jason Chapman, and his team studied the migration of insects for over ten years in England.
Chapman and his team closely monitored the seasonal movement of thousands of insect species. Using specialized tools, which include narrow beams of radar that point straight up, they can spot the biggest insects. In order to track smaller insects, nets that are sent up into the sky on small blimps.
These methods used to track insect migration allow researchers to see what insects are flying high and how they manage to travel with fast-moving air currents.
The research team discovered that the most insect migration happens during the daytime hours and overall, the northward movement was done in the spring months.
Scientists want to continue to research these insect migrations patterns across the globe in order to map how insects move around the world and how they carry nutrients and diseases with them.
Insects are very important to the environment, and although we prefer them to stay outside where they belong, studying their migration patterns will help us gain more information on how they might impact us.
