03F387A7FFA6FFAFFC62FE26FBE4FCE0.taxon	discussion	The imago of E. nostras is of the same size as M. bore, with a forewing length of 25 – 33 mm. The presence of several dark spots on the wings of E. nostras makes it easily recognisable, as they are absent from the other Danish antlion species (Figures 1 (c) and 2). E. nostras is without bright spots on the dorsal side of prothorax, and neither the males nor females have Eltringham’s organ (Nielsen 2015).	en	Petersen, Nicholas Hüsig, Nielsen, Ole Fogh, Vilhelmsen, Lars (2022): Presence of populations of antlions (Neuroptera: Myrmeleontidae) in Denmark correlates with presence of aeolian sand.

03F387A7FFA6FFAFFC62FE26FBE4FCE0.taxon	description	The larva is reddish brown, the ventral side of the head is pale and with several spots, a pair of elongated dark markings near the median, with another pair of dark spots beneath. The labial palp is four-segmented, and the hind legs are without dark spots. The distal half of the 8 th abdominal sternite is covered by two types of structures – a few black spines and numerous bristles (Friheden 1973; Badano and Pantaleoni 2014).	en	Petersen, Nicholas Hüsig, Nielsen, Ole Fogh, Vilhelmsen, Lars (2022): Presence of populations of antlions (Neuroptera: Myrmeleontidae) in Denmark correlates with presence of aeolian sand.

03F387A7FFA6FFAFFCBDFCE5FC6CFABF.taxon	discussion	The imago of M. formicarius is the largest neuropteran in Denmark with a forewing length of 35 – 40 mm (Figure 3 (a )). In addition to differing from M. bore in length, the wings are also wider, and M. formicarius can also be identified by its bright and broad spots on the pronotum (Figure 3 (b )), which are clearer and more distinct than those on M. bore (Nielsen, 2015). The dark brown larva has spots on the hind coxa and femora; it is the only antlion species in northern Europe with this trait. Furthermore, the larva is equipped with dolichasters between the base and first tooth of the mandibles. The ventral side of the head is pale, covered by several dark spots, and a pair of significantly larger spots. The larva has four-segmented labial palps. The distal half of the 8 th abdominal sternite segment is similar to M. bore, being covered by only short, black spines and without setae. The 3 rd instar of the larva is considerably larger than that of the other species in Denmark (Friheden 1973; Badano and Pantaleoni 2014; Nielsen 2015).	en	Petersen, Nicholas Hüsig, Nielsen, Ole Fogh, Vilhelmsen, Lars (2022): Presence of populations of antlions (Neuroptera: Myrmeleontidae) in Denmark correlates with presence of aeolian sand.

03F387A7FFA6FFAEFCC7FA30FEBFFEE8.taxon	discussion	The imago of M. bore has a forewing length of 25 – 33 mm (Figure 3 (c )). The wings are narrower than those of M. formicarius, which M. bore is easily confused with. Just like M. formicarius, M. bore also has bright spots on the pronotum, however, they are less distinct and might be completely absent. Adult males of M. bore has a small club-like organ called the Eltringham’s organ at the posterior margin of the hindwings, which helps distributing pheromones (Figure 3 (d )) (Elofsson and Löfqvist 1974; Lipovsek Delakorda et al. 2009; Nielsen 2015; Zhang et al. 2015). The larva is greyish to pale brown, the ventral side of the head is pale and with a pair of dark spots. The labial palp is three-segmented, and the hind legs are without dark spots. The distal half of the 8 th abdominal sternite segment is similar to M. formicarius, being covered by only short, black spines and without setae (Friheden 1973; Badano and Pantaleoni 2014).	en	Petersen, Nicholas Hüsig, Nielsen, Ole Fogh, Vilhelmsen, Lars (2022): Presence of populations of antlions (Neuroptera: Myrmeleontidae) in Denmark correlates with presence of aeolian sand.
