The list (with short description) of localities on which Dolerus germanicus (Fabr.) has been found is presented in Table 1, and general distribution of the species in Poland on Map 1. Most of the specimens were collected by the authors of this paper. Two specimens were caught by M. Bidas (see paragraph “New localities”). All specimens have been deposited in the Department of Forest Protection and Ecology SGGW, in Rogów. Table 1. List of localities of Dolerus germanicus (F.) in 2012-2017.

Host plant: Equisetum spp. Geographical distribution: The D. germanicus germanicus occurs almost throughout Europe, especially in the central and southern parts of it. Subspecies D. germanicus fuscipennis (Steph.) is known from the northern part of Sweden and Kamchatka; D. germanicus sibiricus Zhelochov. occurs in the northern part of Russia and D. germanicus subsolanus Zhelochov. in the eastern part of Russia (Haris 2000; Taeger & al. 2006, 2010; Sundukov and Lelej 2009). Fig. 1. Dolerus germanicus (F.) – a right penis valve of male aedeagus (outer view). One of the most common the horsetail-infesting species of the genus Dolerus. Occurs as well in wet places near water as in arid, xerothermic habitats. Males and females appear simultaneously, flying in May, with the peak of swarming in the second and third decade (Fig. 2); specimens observed in July, of distinctly darker wings, seem to belong to the second generation. Representatives of this species – especially those flying in July and August – -254- World Scientific News 90 (2017) 251-256 frequently feed on flowering umbelliferes – the author (JB) observed them on flowers of Pastinaca sativa L. and Heracleum sphondylium L. 3/II 1/III 2/III 3/III 1/IV 2/IV 3/IV 1/V 2/V 3/V 1/VI 2/VI 3/VI 1/VII (...truncated)
