This species shows a substantial geographic and individual variability. Large specimens from the Balkans were described as balcanica Zukowsky, 1929, small and dark specimens from the same area as ljiljanae Toševski, 1986, and extensively yellow marked specimens from Armenia as armeniaca Bartel, 1906. Similar but paler specimens occur in central Anatolia. Laštůvka (1990c) carried out extensive morphological studies of this species, including genitalia dissection of more than 130 specimens from various regions, and found no consistent differences between these forms.
The DNA barcode sequences split P. triannuliformis into at least three distinct clades. Although we did not observe reliable morphological differences between these clades, it is pssible that they constitute distinct species or subspecies. To address this issue comprehensively, it will be required to re-examine the type material of all taxa currently subsurmised under P. triannuliformis. In particular, attention will have to be payed to the morphology and barcodes of specimens from north-western Turkey, the type locality of P. triannuliformis. Given that several distinct barcodes seem to cluster around the Black Sea, it will also be necessary to locate the types or designate neotypes for Sesia triannuliformis, Sesia braconiformis Herrich-Schäffer, 1846, and Sesia armeniaca Bartel, 1906 to stabilized the nomenclature of this group.
Barcodes. RAxML analysis recovers P. triannuliformis as monophyletic group; however, it shows substantial heterogeneity based on DNA barcode sequences. The average intraspecific differences are very high with 5.5% and reach a maximum of 8.2%, highly indicative of hidden diversity. P. triannuliformis falls into three distinct clusters with high geographic correlation. The first cluster includes specimens from central and south-eastern Europe, the second cluster contains a specimen from Georgia, and the third cluster specimens from Turkey and Armenia.
Biology and habitat. Various species of Rumex constitute the hostplants of this species; the following are listed in the literature: R. conglomeratus, R. crispus, R. palustris Smith, R. thyrsiflorus, R. scutatus Linnaeus, R. acetosa, R. acetosella (Kallies & Sobczyk 1993, Špatenka et al. 1996, Špatenka et al. 1999, Lepidopterologen-Arbeitsgruppe 2000, Laštůvka & Laštůvka 2001, Laštůvka 2007). Špatenka et al. (1996) also mentioned Geranium sanguineum as occasional hostplant. The larvae, seldom more than one, feed in the main root and develop over one year.
Distribution. This species occurs in a wide, partially scattered range from south-western France, southern and northern Italy, central and eastern Europe, through the Balkans, the Ukraine, the Baltic states, southern Russia and Turkey to the Middle East, the Caucasus region, the Caspian Sea coast and northern Iran (Laštůvka & Laštůvka 1995, 2001, Špatenka et al. 1999).
Note. Most of the standard literature (e.g. Špatenka et al. 1999) cites 1842 as publication year for this taxon. However, we follow the conclusions of Olivier (2000) and consider 1843 the year of publication.
