Growth rate

As the energy source for photosynthesising plants, light is crucial for growth. Some plants require high light intensity, while others are adapted to shade.

Photoperiod, or the period of daylight, is used by insects and plants as a trigger for many processes including initiation or termination of diapause or dormancy.

Birth rate

Photoperiod may also trigger flowering in plants and reproduction by insects.

Behaviour

Mating, flight and other key behaviours of insects can be controlled by light intensity or photoperiod. Some are attracted by light but others are repelled.
