Tracking Flowers

Hawk moth

Manduca Hawkmoth Resting on A Branch

Hawk moths feed on flowers by hovering with their long proboscis extended. By fine tuning their movements, the moths are able to feed even when the flower is swaying in the breeze. Measurements of flower movements find that over 90 percent of flowers sway at a frequency of under 2 Hz (cycles per second). The wings of the hawkmoth beat at about 25 Hz. The moth maintains a wingbeat that is 10 times faster than the typical flower motion, allowing the moth to adjust its position faster than the flower is moving.
