Retrieval of Dragonfly Data

This article is about accessing data collected by the British Dragonfly Society Recording Scheme. We believe in Open Data and are keen that the records we collect and curate are used widely to inform conservation management, development planning, species & ecological studies and climate change research. To these ends we publish to the National Biodiversity Network Atlas (NBN Atlas) from where it may be accessed freely.

We reprocess the data from our entry, maintenance and verification system iRecord, hosted for us by the Biological Records Centre (BRC), to give the records a more consistent format and filter out those that do not make the grade.

Records from some iRecord sources arrive with a licence type that is not sufficiently ‘open’. An example is the Creative Commons NonCommercial licence (CC BY-NC), as used by default for iNaturalist records. We do not pass these, and other restrictively licenced records, to NBN Atlas. We are making efforts to persuade recorders to adopt the Creative Commons by Attribution (CC BY) licence type.

 

Accessing the NBN Atlas

NBN Atlas is a natural world data aggregator for the UK. It facilitates searching, listing, mapping, correlating and downloading. Some features, including downloading of records, require an account.
We recommend you restrict your reviews of Odonata (dragonflies & damselflies) to our data resource because there are other resources on NBN Atlas that have not received the same degree of checking (“verification”). In particular, occurrence maps can be significantly distorted by plotting only a few incorrect records.

Use these links to find our data on NBN Atlas:

The resource page shows the latest information (metadata) about the data resource, including the date range, when it was uploaded and any known issues with the data.

 

Accessing the Global Biodiversity Information Facility (GBIF)

The same data resource that we send to NBN Atlas is passed on to GBIF. As the name suggests, this is a natural world data aggregator for the globe. Some features, including downloading of records, require an account.

Caution!

As of 22 April 2026, downloads from NBN Atlas do not export Stage values (other than ‘adult’) correctly in column ‘Stage’ of the spreadsheet. Stages such as ‘copulating pair’, ‘larva’ and ‘exuvia’ appear as null. Furthermore, the data passed to GBIF by NBN Atlas show the same problem.

We recommend not to download records for research until further notice. You can, however, recover these values from the two-character suffix in the occurrenceID column. For example, record 3afb3aef-b72f-4778-a9ab-53a0c4aa4ef2 has occurrenceID iBRC44732952.Co that corresponds to stage ‘Copulating pair’. The full lookup table of stage suffices is:

Suffix Stage
Ad adult
Co copulating pair or tandem
Ov ovipositing female
Sc oviposition scars
La larva
Ex exuvia
Em emergent

 

We are working with NBN to resolve this issue. If you need exports urgently please contact the BDS Records Officer.
