The remarkable larva of this species has a surprisingly long history of misidentifications with A. occitanica (Dufour 1854; Ferrari 1864; Girard 1875; Dubois 1899) and even with Palpares (McLachlan 1873; Navás 1923). The first description with correct identification was realized by Redtenbacher (1884), followed few years later by an anatomic study by Meinert (1889) despite the latter author identified this species as “ Myrmeleon pallidipennis Rambur?”. The best study on the biology of this species is the excellent work of Principi (1947) dealing the life cycle, the larval morphology, ecology and behaviour. This antlion is probably the better known European non pitbuilding species being extensively studied (Richard 1952; Richard & Pons 1952; Saffré 1957; Steffan 1975; Stange & Miller 1985; Gepp & Hölzel 1989; Gepp 2010; Krivokhatsky 2011).

Description of 3 rd instar larva. Size (based on 12 specimens): BL 19.60 mm; HL 4.55 mm (4.09–5.00), HW 3.62 mm (3.10–4.27), ML 3.55 mm (3.51–4.42), HW/HL 0.80, ML/HL 0.78. General colouring very pale, sandlike with a conflicting black pattern on the dorsal side, ventral side whitish, unmarked; head capsule with a dorsal pair of large dark markings (Fig. 25b), lateral and ventral sides unmarked (Fig. 25c); mandibles light brown with a dark apex; legs pale; body covered by both black and robust setae and by whitish hair-like ones. Head rectangular, longer than wide; mandibles strong, slightly shorter than the head capsule (Fig. 25a); interdental mandibular setae: (0)(1–2)(1–2)(0); short setae are disposed on the external margin of the mandibles from the base to the apical tooth. Mesothoracic and abdominal spiracles dark. VIII abdominal sternite covered by large setae, thicker in proximity of the distal margin; IX sternite triangular in shape, with a transversal series of dark digging setae, caudal margin provided with large setae (Figs. 2F, 25d).
Bio-ecology. S. baetica is strictly associated with extensive sandy biotopes with limited vegetal covering, therefore it is a characteristic element of open coastal sand dunes although also reported from internal sandy habitats. It is a particularly common species in relatively undisturbed coastal dunes of the Mediterranean. The larvae of S. baetica are often buried at the base of psammophilus plants, where they are protected from atmospheric agents. The larvae are aggressive and active predators, able to rapidly pursue the prey for a short distance; during the day they are hidden under the sand surface, ambush hunting, while during the night they roam freely on the dunes.
Distribution. A widespread species in the western Palaearctic.
Remarks. Highly unmistakeable larva without closely related species in the western Palaearctic.
