Perch Selection by Three Cooccurring Species of Celithemis (Odonata: Libellulidae): Testing for a Competitive Hierarchy among Similar Species

Figure 6

The frequency at which Celithemis ornata, C. elisa, and C. fasciata attacked perched individuals of these species, compared to expected frequencies based on relative mean hourly abundance counts averaged over the entire sampling period of May–July 2015 (; , chi-squared goodness of fit tests).
