Lasiocampa trifolii, the grass eggar, is a moth of the family Lasiocampidae first described by Michael Denis and Ignaz Schiffermüller in 1775. It is found in Europe. Illustration from John Curtis's British Entomology Volume 5 The wingspan is 40–55 mm. The moth flies from June to September depending on the location. The larvae feed on various shrubs and deciduous trees, such as oak, European beech, poplar and Calluna.

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 Lasiocampa trifolii 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. 95% of positions are identical in every specimen.
Where individuals differ — all 32 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.

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.
