虽然几个感官使用的竞争和性行为的Eublepharis macularius和Paroedura pictus，不同的线索不具有相同的相对价值的两个物种的男性。在麻醉同种的存在下观察到的行为模式的两性差异很大。对E.斑点的反应时间和其他行为的频率和持续时间经历了渐进的变化。攻击行为最终几乎完全消失在P. pictus身上，取而代之的是性行为，无论刺激动物的性别如何;蜥蜴似乎无法区分雄性和雌性。这两个物种的激动行为是敏感的同种的不动性，虽然程度不同。这些数据与在更自然的条件下进行的观察一致;物种之间的性别识别标准不同。E.斑鱼主要依靠化学信号进行性别识别和与性别有关的行为。在主要依赖视觉信号的红腹蛛中，同种姿势和行为是引起性反应和对抗反应的主要因素。
Although several senses are used in agonistic and sexual behaviours by Eublepharis macularius and Paroedura pictus, different cues do not have the same relative value for males of the two species. Behavioural patterns observed in the presence of anesthetized conspecifics of both sexes differed considerably. The agonistic and sexual behaviours of E. macularius underwent progressive changes in reaction time and the frequency and duration of other behaviours. Aggressive behaviour eventually almost completely disappeared in P. pictus and was replaced by sexual behaviour, whatever the sex of the stimulus-animal ; the lizards then appeared to be incapable of distinguishing males from females. Agonistic behaviour of both species was sensitive to the immobility of the conspecific, although to different degrees. These data concur with observations carried out under more natural conditions; sex recognition criteria differ between the species. E. macularius relies primarily on chemical signals for sex recognition and sex-related behaviours. In P. pictus, which depends primarily on visual signals, conspecific posture and behaviour are the main factors responsible for both sexual and agonistic reactions.
