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:
MX.5077966
MX.5077965
MX.5077967
MX.5077970
MX.5077969

Data quality: The quality of data is, as of 23th May 2023, unknown. Data may include incomplete lists, overtly long or short observation efforts or mislabeled observations. Data curation is necessary before using data for research.
