Actebia praecox, the Portland moth, is a moth of the family Noctuidae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. It is found in northern and central Europe, the Caucasus, central Asia, Siberia, Kamchatka, Sakhalin, the Kuriles, northern Turkey, Mongolia, China, Korea and Japan. Illustration from John Curtis's British Entomology Volume 5 Moth and larva (figures 4) alongside related species in Karl Eckstein Die Schmetterlinge Deutschlands The wingspan is 35–40 mm. "Forewing narrow and elongate, dull pale green, dusted with whitish; the three stigmata ochreous concisely black-edged; orbicular round, with a rounded rufous centre, reniform with a fine angled line swollen at each end; submarginal line preceded by a dull vinous band; apex whitish; hindwing fuscous brown. — ab. flavomaculata Graes., bluish green with the ochreous tints more yellow and the hindwings much darke-r, is confined to the Asiatic localities, but Leech states that some Irish specimens resemble it."Seitz, A. Ed., 1914 Die Großschmetterlinge der Erde, Verlag Alfred Kernen, Stuttgart Band 3: Abt. 1, Die Großschmetterlinge des palaearktischen Faunengebietes, Die palaearktischen eulenartigen Nachtfalter, 1914 The caterpillar is light grey, or greenish coloured, has a dark lined yellowish back stripe with adjacent striking, ornamental, bright markings as well as yellow dorsolateral lines and a wide, white lateral stripe. The very slender pupa is shiny reddish brown and has a long thorn on the cremaster. It is almost exclusively found on sandy terrain, for example in dune areas, sandy fields, shore regions and sand heaths. The larvae feed on Salix repens and other sand-dune plants.

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 Actebia praecox 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.

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.

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.

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.
