Bumblebees – complete lists

Checklist of Finnish bumblebees Bombus s.l., as well as Apis mellifera and solitary bees. One species, Bombus wurflenii, is not included since there is one Finnish record from 1926.

The list follows Finnish Environmental Agency SYKE’s bumblebee recording scheme https://www.syke.fi/hankkeet/polyhyoty

The records include complete checklists of observer trips. Observers mark down each species or taxon they have observed. The data is presence-absence or, optionally, presence-absence with abundance data. Abundance is recorded either in logarhitmic scale (0 = 0 individuals, 1 = 1-10 individuals, 2=10-100 individuals, 3=100-1000 individuals, 4=1000+ individuals) or as precise user input. Observations must include location, date and time data. Properly filled checklists should be considered to show real absences.

The list includes several aggregate taxa. The aggregates include different species that are similar and difficult to tell apart in field conditions. Aggregates are:
