Antheraea yamamai, the Japanese silk moth or Japanese oak silkmoth (Japanese: or ) is a moth of the family Saturniidae. It is endemic to east Asia, but has been imported to Europe for tussar silk production and is now found in southeastern Europe, mainly in Austria, northeastern Italy, and the Balkans. It seems to be spreading north and a population has been reported near Deggendorf and Passau in Germany. The species was first described by Félix Édouard Guérin-Méneville in 1861. It has been hybridized artificially with Antheraea polyphemus of North America.See Antheraea polyphemus, Gary Botting Front view of a male specimen Egg Second-instar larva Cocoon This moth has been cultivated in Japan for more than 1000 years. It produces a naturally white silk that is very strong and elastic, but does not dye well. It is now very rare and expensive. The wingspan is 110 –. Adults are on wing from August to September in one generation depending on the location. The larva mainly feed on Quercus species, but have also been reported on Fagus sylvatica, Castanea sativa, Carpinus, Rosa, and Crataegus. In order to look at the tensan silk genes in more detail a de novo genome and set of transcriptomes have been sequenced, producing a 700Mb reference with 15,481 genes.

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 Antheraea yamamai has left across the world's sequence archives.
At a glance
★ the standard DNA barcode for this group — the short region actually read to tell this species apart. The rest are extra genes sequenced along the way.
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.
The complete instruction manual Antheraea yamamai carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.
Genome sizehow big the whole instruction manual is
Measured in base pairs (bp) — the individual letters of DNA (human ≈ 3.2 Gb, a bacterium a few million). The chart places this genome on a logarithmic scale — each step to the right is ten times bigger — among reference organisms. Across species a bigger genome loosely tracks with larger cells, slower growth and lower-energy lifestyles (powered flight favours small genomes) — yet it does not imply more genes or a more advanced organism (the long-standing C-value paradox).
Chromosomes & ploidyhow the DNA is packaged
2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants.

Sequencing statusassembly quality — how far to trust these numbers
Assembly level tells you how finished the sequence is — from fragmented contigs, through scaffolds, up to a full chromosome-level assembly. BUSCO % estimates completeness: the share of genes expected to be present that were actually found. These describe the data quality, not the organism.

Where the DNA of Antheraea yamamai 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 strong is each trace?
Modelled climatemodelled
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.
