Methods

A modified Robinson light trap was installed 17 5 m aboveground at the roof of the Zoological Museum in Copenhagen.Denmark (N 55 702512?. E 12 558956?). A 250 W mercuryvapour bulb was used as light source. In the trap. 1.1.2.2-tetrachlorethanewas used as killing agent. The trap was emptied onan approximately weekly basis and was active from April?November 1992?2009. All individual records of Lepidopteraand Coleoptera were collected. identified to species level andcounted yielding qualitative (species) and quantitative (numberof individuals within each species) data for the entire study period.All handling and identification of material was carried outconsistently throughout the entire period by the same three persons:for Lepidoptera (OK) and Coleoptera (initiated by thelate Dr. Michael Hansen and completed by JP). The final dataset was subjected to a thorough quality check. and the fewrecords (<20 individual records) that could not be accountedfor by comparison of collection periods were discarded. Weexcluded the first (1992) and the last year (2009) of the dataset to minimize start-up effects (operating the trap in a standardizedmanner comparable to the remainder of the study period)and influence from alteration of the local habitat in 2009.Furthermore. in 1992 and 2009 the trap was not active in theentire season. To account for variation in sampling intervals.we grouped the data set into standardized 10-day periods thefirst starting on 1st of January (Julian Day 1) and the last periodending on December 26 (Julian Day 360). The 10-day intervalis slightly longer than the mean sampling interval of7 days Quantitative light trapping of 1543 moth and beetle species from 1992 - 2009 Unit of abundance = AggregatedCount, Unit of biomass = NA
