Fig. 4 in Dead-twig discrimination for oviposition in a cicada, Cryptotympana facialis (Hemiptera: Cicadidae)

Fig. 4 Frequency and duration of probing behavior of Cryptotympana facialis females on different oviposition substrates. a The number of probing behaviors per female during a 90-min observation period. b The mean duration of a single probing behavior. The number of females is indicated at the top of the graph. Groups marked with the same alphabetical letter were not significantly different (a likelihood-ratio test of GLM and post hoc multiple comparisons, p> 0.05). For details of Tukey box plots, see Fig. 2
