20.500.12556/DKUM-12684 Gradnja lijakov ličinke volkca Euroleon nostras (Neuroptera: Myrmeleontidae) v pesku različnih granulacij Pit construction of antlion larva Euroleon nostras (Neuroptera: Myrmeleontidae) according to different grain size of sand Raziskovali smo gradnjo lijakov ličinke volkca Euroleon nostras (Neuroptera: Myrmeleontidae) v pesku različnih granulacij. Volkce smo namestili v štiri podlage: peske z velikostjo delcev 60—110 µm, ≤ 540 µm, 1000—1540 µm in 1540—1750 µm. Volkci so bili dejavni predvsem v poznih popoldanskih in večernih urah. V tem času smo gradnjo lijakov snemali z videokamero in hkrati beležili podatke v snemalno knjigo. S pomočjo teh dveh virov smo pridobili podatke o poteku gradnje in trajanju posameznih faz gradnje lijakov v posameznih podlagah. Volkci v najbolj grobi podlagi lijakov niso gradili. Raziskave podpirajo domnevo, da gre pri vedenju volkcev za določeno plastičnost. We observed and analyzed pit construction of antlion Euroleon nostras in sands with different grain sizes. Larvae of the antlion were placed in four different sands. The particle sizes used in the research were the following: 60–110 µm, ≤ 540 µm, 1000–1540 µm and 1540–1750 µm. Antlions were particularly active in the late afternoon and in the evening. During that time, we recorded pit construction with a video-camera and took notes of the process. Antlions did not build pits in the coarsest sand. We recorded stages of pit construction and duration of the stages. The results support a suggestion that certain plasticity occurs in antlion behaviour.
