Abstract
Artificial light at night (ALAN) as well as heatwaves are global change stressors that may be linked to insect population declines. We conducted a study of ALAN on moth survival and mating behavior. We also conducted a meta-analysis of the effects of heatwaves on insect attributes as well as the impact of heatwave experimental design attributes. With our ALAN experiment, we found that ALAN negatively affects FW mating and may also have a negative impact on FW survival. With our meta-analysis, our findings suggest that heatwaves could be a significant factor in insect declines given that the strongest negative effects are on the most abundant and speciose groups as well as on the fitness measures most related to population declines.
