Sphenophorus melanocephalus is a species of beetle in the family Curculionidae found in North America. Because type specimens were unavailable, the name once was misused for a different species, Sphenophorus nubilus.

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 Sphenophorus melanocephalus has left across the world's sequence archives.

09Environmental DNA1 detections
Where the DNA of Sphenophorus melanocephalus 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.
