insects

Many insects fly synchronously, matching the nervous system pulses to wing movement. But smaller insects don’t have the mechanics for this and must flap their wings harder, which works only up to a certain point. That’s where asynchronous flight comes in.

In response to changing climates, many plants and animals are moving to higher elevations, seeking cooler temperatures. But a new study finds that flying insects like bees and moths may struggle with insurmountable issues to this escape route.
