01Narrative
Polyura narcaeus, the China nawab, is a butterfly in the family Nymphalidae. It was described by William Chapman Hewitson in 1854. It is found in the Palearctic and Indomalayan realms.Seitz, A., 1912-1927. Die Indo-Australien Tagfalter Grossschmetterlinge Erde 9

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 Polyura narcaeus 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. 98% of positions are identical in every specimen.
Where individuals differ — all 12 variable positions, in barcode order
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.

Closest relatives by DNA barcode
The species whose COI barcode is most similar to this one — a quick “who is this most like”. The percentage is how much the barcode differs; it approximates, but is not, the full evolutionary tree.
★ the standard DNA barcode for this group — the short region actually read to tell this species apart. The rest are extra genes sequenced along the way.

Organelle genome
Besides the big genome in the nucleus, cells carry a small, circular loop of DNA inside the cell's energy factories — the mitochondria. It is inherited almost only from the mother and is a leftover from ancient bacteria that moved into the cell. The mitochondrial markers above (ND*, COX, CYTB…) are read from exactly this loop. Outer ring = one strand, inner ring = the other.

◖ violet arc = the COI-5P barcode — the ~650 bp read used to ID this species
Pick a coloured segment on the ring — or a gene chip — to read what that gene does.
