UK aphid migration percentiles, covariates and model outputs from the Rothamsted Insect Survey's 12.2 m suction-trap network: 1965 to 2018

This dataset contains a measure of aphid arrival, the day of 1% detection (D1D), i.e. the Julian day at which 1% of the yearly aphid abundance has been captured. It is measured for 14 aphid species across the UK, from 1965 to 2018, by the Rothamsted insect survey suction-trap network. It amounts to a total of 881 samples (i.e. trap x year combinations). For all those samples, a measure of 59 covariates as potential predictors are given. They include monthly temperature averages (HadUK grid), monthly precipitation averages (HadUK grid), land-use composition (CORINE), elevation and distance to sea. In addition to this training data, a second part of the dataset consists of those covariate measurements on a 5km x 5km resolution grid of the UK for the years 2015 to 2018. This second part of the dataset offers the possibility of spatiotemporal predictions of the D1D by a model trained on the first part of the dataset. Five coordinates are given: year, northing and easting (of the Ordnance Survey National Grid reference system), latitude and longitude.

The Rothamsted Insect Survey operates two trap networks throughout the United Kingdom that sample aphids and moths using suction-traps and light-traps, respectively. More information about the network and data collection processes can be found at https://insectsurvey.com/.

Data were extracted from the RIS database ‘Paul’ that holds records of moths and aphids.
