Pit-building antlion Euroleon nostras constructs efficient traps in sand to catch its prey. The predator is known to react to substrate vibrations produced by movements of its prey outside the pit with sand-tossing behaviour but it has not yet been ascertained if this reaction is directed towards the prey. The accuracy of the sand-tossing response in the presence of four prey species was measured using a video recording method. The sand-tossing angle was highly positively correlated with the prey angle. Sand tossing was most frequently elicited when prey was on the posterior sand surface. Covering the larval photoreceptors did not influence the antlion's localizing behaviour.
筑坑蚁狮Euroleon nostras在沙中构建高效的陷阱来捕捉猎物。已知这种捕食者会对坑外猎物移动产生的底物振动做出反应，表现出抛沙行为，但尚未确定这种反应是否针对猎物。使用视频记录方法测量了在有四种猎物物种存在时抛沙反应的准确性。抛沙角度与猎物角度高度正相关。当猎物位于沙坑后部表面时，抛沙行为最常被引发。覆盖幼虫的光感受器并不影响蚁狮的定位行为。
