Insect activity (treatment estimates from a linear mixed effect model with light treatment as fixed, and site as random effect) as measured with sticky sheets with lights on (a) and off (c), and (b) and (d) group 2 total bat passes (Pipistrellus species; back-transformed treatment estimates from negative binomial generalized linear models with bat passes and site as fixed effects) during the same nights. Capitals identify groups that significantly differ from each other in post hoc tests (electronic supplementary material, table S3).
