Ancyloxypha numitor, the least skipper, is a North American butterfly in the family Hesperiidae. They have a weak, Satyrinae-like flight.Rick Cech and Guy Tudor (2005). Butterflies of the East Coast.

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 Ancyloxypha numitor has left across the world's sequence archives.

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.

09Environmental DNA35 detections
Where the DNA of Ancyloxypha numitor 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.
