As part of a series of articles on International Bee Day 2021, The Independent mentioned work by Eleni on modelling bumblebee citizen science data. In particular, the article referred to results published in 2018, which suggested that even some common species of bumblebee are now in decline.

Recent analysis, using the new and freely available RShiny app, developed by research student Fabian Ketwaroo, suggest that the number of queens emerging from hibernation each year for species  Bombus pascuorum and Bombus hortorum continue to be stable in recent years compared to 2011, when BeeWalk data were first collected.

At the same time there is some indication of positive news for species Bombus lapidarius, also known as the red tailed bumblebee, as the number of queens emerging from hibernation is on the rise in recent years, with 2019 seeing a similar number of queens to 2011. (see plot above, showing the number of queens emerging each year in comparison to 2011).
