They are generally found in Asia (Indomalaya ecozone). Collectors have found the red-bodied swallowtails difficult to kill. Pinching the thorax, a method which kills most butterflies, is withstood and apparently only stuns the butterfly temporarily. The eggs are simple. The larvae resemble those of other Troidini. Fleshy spine-like tubercles, often with red tips, line the caterpillars' backs, and their bodies are dark red to brown and velvety black or shades of grey with a pattern of black lines. They feed
Syntonic comma amount by which Didymus corrected the Pythagorean major third (81:64, around 407.82 cents) to a just major third (5:4, around 386.31 cents). The word "comma" came via Latin from Greek κόμμα, from earlier *κοπ-μα = "an act of cutting". The prime factors of the just interval 81/80 known as the syntonic comma can be separated out and reconstituted into various sequences of two or more intervals that arrive at the comma, such as 81/1 * 1/80 or (fully expanded and sorted by prime) 1/2 * 1/2 * 1/2 * 1/2 * 3/1 * 3/1 * 3/1 *3/1 * 1/5.
