01Narrative

Eresus kollari, the ladybird spider, is a spider species in the family Eresidae. It is one of the three species into which Eresus cinnaberinus or Eresus niger has been divided. Eresus kollari keep the remains of their prey stacked in the web. The females use the same burrow throughout their whole life. The prey can be large like tenebrionoid beetles, up to 32.5 mm long.

05DNA & barcoding14 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 Eresus kollari has left across the world's sequence archives.

▸ drag or hover over the strip to read any position — letter and how much it varies

Violet ticks below the strip = positions where individuals differ; flat = the species' unchanging signature. 90% of positions are identical in every specimen.

Variant network

Each circle is a barcode variant; bigger = more specimens, colour = region. Lines join the most similar variants and the tick marks count the mutations between them — a tight cluster is one “dialect”, a long line a more divergent lineage. Click a circle to list its actual specimens.

09Environmental DNA2 detections

Where the DNA of Eresus kollari 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 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.
