We sampled the abundance and diversity of flower-visiting insects in paired olive farms located in Andalusia. The surveys were carried out in 18 paired olive farms in 2018, and in 24 paired olive farms in 2020. On the one hand, each pair of olive farms is constituted by an olive farm with low-intensive herb cover management and an olive farm with intensive herb cover management. The low-intensive management consists of the maintenance of herb cover during most of the year being only removed in late spring by mechanic mowing or livestock grazing. Conversely, intensive management consists of removing the herb cover permanently by using pre-emergence and/ or post-emergence herbicides, sometimes in combination with ploughing the ground several times a year. On the other hand, the pair of farms in each locality is surrounded by the same landscape complexity. We classified each pair of farms into three categories of landscape complexity (simple, intermediate, and complex) according to the proportion of semi-natural area estimated within a 2 km radius buffer around the centroid of each pair of farms. Surveys were conducted in multi-specific floral stands. We selected two 10 m2 multi-floral stands per olive farm located inside the olive field matrix. They were carried out twice for 2018, and monthly from March to June for 2020 (3 sampling rounds in total), matching the peak flowering period of the ground herb cover. Sampling consisted of recording the abundance and diversity of flower-visiting insects in each floral patch for 15 minutes in the morning (until 13 h) and for 15 minutes in the afternoon (until 17 h) every sampling round. The diversity and abundance of insect floral visitor by transect was pooled by population/locality ('SUMMARY_Floral_visitors_pop.csv' file)., Proyecto SUMHAL, LIFEWATCH-2019-09-CSIC-13, POPE 2014-2020., Our aim was to assess the effect of agricultural management and landscape context of the olive groves on the flower-visiting insect community., This work was funded by RECOVECOS project -Evaluating the Recovery debt of ecosystem services provided by the fauna in permanent croplands: effects of land use intensification and landscape complexity in olive groves- (Ref.: PID2019-108332GB-100, MICIN/AEI/10.13039/501100011033), LIFE Program project OLIVARES VIVOS (ref.
