"Much of our knowledge of insect migration comes from direct observations.
These include observations made using radar, or studies of population
processes, such as using genetic methods, or measuring ratios of isotopes in
tissues (which can reveal insects’ food and water sources and provide
information on where they come from).
How individual insects behave, and the paths they take, during migration has
been relatively difficult to study, mostly due to their small size and the
sheer number of them. But recent advances in tracking technology have helped
produce transmitters small enough to be carried by larger insects.
These transmitters weigh less than a gram and can be attached to individual
insects. This allows us to track them directly as they migrate and learn what
this process involves."
That is impressive technology!
