Lyctus brunneus is a xylophage (wood-eating) insectWood Eating Bugs - Insects That Eat Wood, Animal Wised, accessed 31 July 2020. a species of beetle in the family Bostrichidae. It is a member of the subfamily Lyctinae, the powderpost beetles. It is known commonly as the brown powderpost beetleLyctus brunneus. PaDIL. or brown lyctus beetle. Today it is distributed worldwide but it was probably originally native to the Neotropical realm.Ebeling, W. Chapter 5: Wood-Destroying Insects and Fungi. Urban Entomology. UC Riverside Entomology. Like other powderpost beetles, this species lives in wood.Pest Notes: Wood-Boring Beetles in Homes. Agriculture and Natural Resources, University of California. UC ANR Publication 7418.

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 Lyctus brunneus 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 8 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.

Where the DNA of Lyctus brunneus 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.
