01Narrative

Andrena krigiana is a species in the family Andrenidae ("mining bees"), in the order Hymenoptera ("ants, bees, wasps and sawflies"). The species is known generally as the "dwarf-dandelion andrena". It is found in North America.Sharkey M.J. (2007).

05DNA & barcoding1 specimens

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Andrena krigiana has left across the world's sequence archives.

09Environmental DNA1 detections

Where the DNA of Andrena krigiana was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How strong is each trace?

DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
