Supplement 1. Dates of laying, hatching, and peak insect biomass used in Table 1.

File List Data.txt Description The data.txt file is a tab-separated ascii file. The file contains the raw data used in statistical analysis of laying and hatching dates in relation to the date of peak insect biomass (see Table 1). Column definitions: Loc = location of study site Year = Year of sample InsectTrap = type of insect sampler (suction or tow-net) 25%Laydate= the 25th percentile of laying dates (1 = 1 May) MeanLaydate = mean date of laying (1 = 1May) DateMaxBiomass = Date of the maximum insect biomass (1 = 1 May) MeanHatchDate = mean date of hatching (1 = 1 May) Column checksum values: column 1: location, 26 values, none missing column 2: year, 26 values, none missing column 3: type of insect sampler, 26 values, none missing column 4: 25th percentile of laying dates, checksum = 447, 26 values, none missing column 5: mean laying dates, checksum = 547.9, 26 values, none missing column 6: date of maximum insect biomass, checksum = 934, 26 values, none missing column 7: mean hatch date, checksum = 1058.3, 26 values, none missing
