This data was primarily used to inform farmers on when the legal economic damage threshold of this insect was crossed. Data was collected by placing three water traps within a field for 7 days. After 7 days the water traps were replaced and the number of female and male chicory miner flies were counted. Since 2025 the water traps have been replaced by sticky traps with algorithmic monitoring. Since this dataset contained 29 years of data it raised the question on how the population of the chicory miner fly was impacted by climatic changes over the last 29 years. Historic weather data was collected both using the KMI's Automatic weather station data for data prior to 2015 and the KMI's WOW-BE platform for weather data between 2016 and 2024. The original coordinate data revealed the names and plots of each farmer. Due to privacy reasons we contacted the farmers and they asked us to anonomize this data. Therefore we report the municipality data of the farms rather than the coordinate data.
