01Narrative
Agriades podarce, the arrowhead Arctic blue, gray blue or Sierra Nevada blue, is a butterfly in the family Lycaenidae. It is found in North America from southern Oregon to central California in the Klamath Range and the Sierra Nevada. The habitat consists of subalpine meadows. The wingspan is 22–26 mm. The upperside of the males is gray blue, while females are red brown. The underside of the forewings has black arrowhead-shaped spots that point inward. The hindwings have a discal spot which is not black.Butterflies and Moths of North America Adults are on wing from June to September in one generation per year. They feed on flower nectar, including yellow composites and bistort. The larvae feed on Dodecatheon jeffreyi.Butterflies of America Caterpillars or chrysalids hibernate.

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 Agriades podarce 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. 99% of positions are identical in every specimen.
Where individuals differ — all 4 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.
