The Armenian cochineal scale insect, Porphyrophora hamelii, is in a different taxonomic family from the cochineal found in the Americas. Both insects produce red dyestuffs that are also commonly called cochineal.
At the time of the Renaissance in Europe, Porphyrophora insects were so valuable that in Constantinople during the 1430s, one kilogram (2.2 pounds) of Porphyrophora hamelii insects was worth more than 5 grams (0.18 ounces) of gold. The crimsonPorphyrophora-based dyes were especially prized in Europe for dyeing silk, as the scarlet dye kermes was more plentiful, cheaper, and more effective for dyeing woolen textiles, which are heavier than silk and require more dye. It has been estimated that on the order of a half million dried Porphyrophora hamelii insects were required to dye one kilogram (2.2 lb) of silk crimson during this period. On the comparison between Armenian and Polish cochineal, the author of a 15th-century treatise on silks in Florence wrote that "two pounds of the large [Armenian cochineal insects] will dye as much [silk] as one pound of small [Polish cochineal insects]; it is true that it gives a more noble and brighter colour than the small, but it gives less dye."
Around the end of the 16th century the Old WorldPorphyrophora dyes were supplanted by dyes of the Dactylopius coccus cochineal species from the Americas, which could be harvested several times per year and yielded a much more concentrated dye.
The carmine dyestuff of Porphyrophora hamelii owes its red color almost entirely to carminic acid, making it difficult to distinguish chemically from the dyestuff of cochineal from the Americas. The dyestuff of Porphyrophora polonica can be distinguished by its small admixture of kermesic acid, which is the major constituent of kermes from Kermes vermilio.
In 1833 the German naturalist Johann Friedrich von Brandt suggested the scientific namePorphyrophora hamelii after the Russian physician, traveler, and historian of German descent Iosif Khristianovich Gamel (Josef Hamel) (ru), who visited the Ararat plain in the early 1830s and wrote a report about the "cochineal" insects living there.

Porphyrophora hamelii is a sexually dimorphic species. The adult female, from which carmine is extracted, is oval-shaped, soft-bodied, crimson in color, and has large forelegs for digging. The females can be quite large for a Porphyrophora species: up to 10–12 mm (0.39–0.47 in) long and 7 mm (0.28 in) wide. It has been noted that one troy pound (360 grams) of cochineal insects requires 18,000–23,000 specimens of Porphyrophora hamelii, but 100,000–130,000 specimens of the sister species Porphyrophora polonica (or 20,000–25,000 specimens of Dactylopius coccus). The adult male Porphyrophora hamelii is a winged insect.
The life cycle of Porphyrophora hamelii is mostly subterranean. Newly hatched nymphs emerge from the ground in the springtime and crawl until they find the roots of certain grassy plants that grow in saline soil, such as Aeluropus littoralis (Armenian: որդանխոտ (genus Aeluropus), literally "worm's grass") and the common reed Phragmites australis. The nymphs continue to feed on these roots throughout the spring and summer, forming protective pearl-like cysts in the process. From mid-September to mid-October adults emerge from the ground between 5 a.m. and 10 a.m. to mate. The adult insects, lacking mouthparts, do not feed. Adult males live for only a few days, but adult females can live longer, burrowing into the ground to lay their eggs.
Habitat and conservation
The historic habitat of Porphyrophora hamelii. Vordan Karmir State Reservation is in red and the historic dye-producing cities Artashat and Dvin are in purple.
The red dye-producing insects of the Ararat plain were once plentiful: a 19th-century French traveler wrote that shepherds' flocks, when led to drink from the Araxes (Araks) River, would appear bloody from the insects. In the mid-20th century the extent of occurrence in Armenia was 100 km2 (39 sq mi) with a recorded distribution that included the Ararat and Armavir provinces in Armenia as well as the Turkish, Iranian, and Russian Caucasus, but by the 1990s the extent of occurrence in Armenia had shrunk to about 20 km2 (7.7 sq mi), mostly in Armavir Province. During the Soviet period, desalination of the Armenian salt marshes to create "economic and agricultural regions", and the creation of lakes for fisheries, "severely restricted the [habitable] area for the insects and [endangered their] existence."
Vordan Karmir State Reservation, Armenia
The population in Armenia resides almost entirely in the Vordan Karmir State Reservation, a salt meadow habitat of 198.33 ha (490.1 acres) northwest of Arazap village and 21.52 ha (53.2 acres) in the north of Jrarat village established in 1987 near the Araks River border with Turkey, plus a site southeast of Ararat village and a few patches of several hectares elsewhere. There have been no recent scientific reports on populations of Porphyrophora hamelii outside the surroundings of Mount Ararat.
Porphyrophora hamelii is considered critically endangered within Armenia by meeting the following conditions: an area of occupancy of less than 10 km2 (3.9 sq mi), plus severely fragmented occupancy or known to exist at only a single location, plus continued decline (observed, inferred, or projected) in the area of occurrence, area of occupancy, and area, extent, and/or quality of habitat; and an extent of occurrence of less than 100 km2 (39 sq mi) with the aforementioned conditions of continued decline.

Vedeler, citing Cardon (2007), notes that "the Persian name Kirmiz originally referred to the Armenian carmine, a parasitic insect living on Gramineae grass, but the same name was also used by Arab geographers for insects living on oak trees in Maghreb and Al-Andalus, probably referring to Kermes vermilio", although "[i]t is ... not clear whether the 'Kirmiz' dyestuff mentioned in early Arab texts always refers to the use of the insect Kermes Vermilio."

^Some articles improperly cite Cardon to suggest, incorrectly, that Armenian cochineal insects were more valuable, by weight, than gold (i.e., one gram of insects was worth several grams of gold) during this era. Cardon (2007) does, however, note that according to the records of a Venetian merchant trading in Constantinople during the 1430s, even the cheapest Armenian cochineal insects were still worth more, pound-for-pound, than some live slaves (Circassian women and adolescents) that he had bought.
^400,000 to 560,000 dried P. hamelii insects were required to dye 1 kg of silk according to the figures of Cardon (2007): 1,000 g to 1,400 g of dried insects per 100 g of silk, with 40 adult females per gram of dried insects. Note that Virey (1840) reports 18,000–23,000 insects per 360-gram troy pound (50–64 insects per gram; not stated whether they were dried).

The red color found on some of the cross stones is a result of their being painted with Vortan Karmir, a red dye made from beetles native to Armenia. The red dye was among the more famous exports of the kingdom, and was valued more than gold in Europe and the Near East. Its resilience has long since proved itself; the color you see now is more than 800 years old.
