RETHERA KOMAROVI (Christoph, 1885)

(Taxonomic note. The various subspecies and forms of Rethera komarovi appear to have developed in several isolated refugia during the last (Pleistocene) ice-age. They have since re-established contact and appear to be merging in a manner similar to Deilephila porcellus (Linnaeus, 1758.). The partitioning of the races in this site is based on morphological features combined with DNA barcoding, although the differences between some of the races is rather small.


RETHERA KOMAROVI KOMAROVI (Christoph, 1885)

GB: Madder Hawkmoth, RU: Komarova Brazhnik, FI: Venäjänkiitäjä.

Deilephila komarovi Christoph, 1885, in Romanoff, Mémoires sur les Lépidoptères 2: 169.

Type locality: Askhabad, near Germob [Ashkhabad, Turkmenistan].


BIOGEOGRAPHICAL AFFILIATION

Holarctic; western Palaearctic region. Pleistocene refuge: Monocentric -- unclear, probably the western half of the Iranian refuge.


ADULT DESCRIPTION AND VARIATION

Wingspan: 55--65mm. Similar to subsp. rjabovi O. Bang-Haas, 1935 and subsp. stipularis (Swinhoe, 1885), but closer to the latter.

Exhibits little variation except for the intensity of 'tint' colours, which range, ventrally, from pale orange to deep pink. Newly-emerged examples often have a magnificent rose sheen. However, due to the fact that the dorsal green coloration fades in strong sunlight, those collected from drier regions tend to be paler than examples from more verdant areas. The same applies when killing agents such as diethyl ether and ethyl acetate are used.


ADULT BIOLOGY

Frequents 'vegetation islands' on sparsely vegetated cliffs and rocky slopes which are cold in winter and become parched in summer.


FLIGHT-TIME

Univoltine; mid-April to the second week of June, depending on location and season.


EARLY STAGES

OVUM: Unknown, but probably identical to that of subsp. rjabovi.

LARVA: Unknown, but probably identical to that of subsp. rjabovi.

Hostplants. Unknown, but probably Rubia and Galium spp.

PUPA: Unknown, but probably identical to that of subsp. rjabovi.


PARASITOIDS

None recorded.


DISTRIBUTION

The Kopet-Dagh Mountains of northeastern Iran and southwestern Turkmenistan.

Extra-limital range. None.

Eastern Turkey, the mountains straddling Jordan, Syria and Lebanon, Armenia, Azerbaijan, Iraqi Kurdistan (Wiltshire, 1957), and from northern Iran south along the Zagros Mountains (Barou, 1967; Ghassemi, Alemansoor & Alehossein, 2009) to the rest of central, southern and eastern Iran (and maybe also western Afghanistan (Ebert, 1969)) as subsp. rjabovi O. Bang-Haas, 1935. Central and eastern Afghanistan (Ebert, 1969), Balochistan and the Hindukush area of western/northern Pakistan (leg. Z. Varga & G. Ronkay, ex coll. György Fábián, coll.
