Extended Data Fig. 9: Distribution of inoperative days through the year.
From: Moth biomass has fluctuated over 50 years in Britain but lacks a clear trend
Panel a shows the number of all trap/year combinations which were inoperative on each Julian day of the year (median: 1.56 % of trap-years inoperative), and reveals that inoperative days were distributed evenly across the entire year (other than a slight increase around Christmas/New Year, when few moths are active). Panel b shows the frequency of inoperative days per trap/year combination, expressed as a percentage of all days in the year, with the median value (0.55 %) shown as a dashed line. Bins are 1 % wide.
