Caterpillar populations decline 50 per cent in areas with streetlights

An LED streetlight can reduce the number of moth caterpillars in an area by up to 50%, potentially having a huge impact on the wildlife ecosystem.

Douglas Boyes, UK Centre for Ecology & Hydrology says that light pollution is not as significant a factor in biodiversity [loss] than climate change. However, this doesn't make light pollution less important.

Previous research has examined the effects of artificial light.
