Distribution. Northern Europe, across Siberia to Primorskij Kraj, North Korea, China (Jilin) (Shinohara & Taeger 2007).

Host plant. Rosaceae: Filipendula ulmaria (L.) Maxim. (Kangas & Syrjänen 1962). Record of Spiraea sp. (Kajmuk 1972; Verzhutskij 1981; Lee et al. 2019) needs confirmation.

Remarks. This is a widely distributed species associated with Filipendula (Kangas & Syrjänen 1962) . It has much in common with O. decorata and O. nigroclypeata whose larvae feed on Agrimonia (Shinohara 2006; Shinohara & Lee 2011). In the COI tree (Fig. 139), O. sertata was retrieved as a sister of the clade represented by O. decorata and O. nigroclypeata but with 93% UFBoot support, which was not high enough to warrant credibility. The maximum p -distance within O. sertata (n=8) was 0.8% and the nearest neighbour, diverging by a minimum of 3.5%, was O. decorata and O. viriditibialis . The NaK tree was not well resolved among the species related to O. sertata (Fig. 153).
