Abstract
Light cycles play a vital role in the organization of the biological world. Increased and global use of artificial light sources at night may disturb these natural light cycles. Moths are especially vulnerable because of their sensitivity to light. I examine how artificial light at night impacts moths and how this can affect other organisms. Moths suffer from increased direct mortality from flight-to-light behaviour. They also show increased indirect mortality from a reduction in predator evasion and foraging. Besides, development and reproductive succes are negatively impacted. All these factors are thought to be one of the major causes in moth population declines. Although experimental evidence remains scarce, cascading effects are likely. Further research on cascading effects and underlying mechanisms of flight-to-light behaviour is required for successful conservation.
