We did not find any significant relationship between the co-occurence of a pair of predators in bromeliads (measured as Pianka's index of niche overlap) and the phylogenetic distance between the two predators. A Mantel test found no evidence of correlation between differences among predators in habitat use, and phylogenetic distance (correlation -0.18, p = 0.84, 999 permutations). This indicates that all 14 predator species have roughly similar habitat distributions -- indeed, we often found multiple predator species co-occurring in the same bromeliads (mean 4.45 ± 2.8 predator species per plant). We were able to sample a wide range of phylogenetic relatedness, including two groups of congenerics -- two species of _Bezzia_ sp. (Diptera:Ceratopogonidae) and three species of _Leptagrion_ sp.

Tabanidae and two species of Empididae, all Diptera. Deeper divisions were also present: three families of Diptera were represented by a single predator species each (Dolichopodidae, Corethrellidae and
Chironomidae) and the deepest taxonomic divide was between all insects present and the predatory leeches (Arhynchobdellida:Hirudinidae).

Overall, predators were remarkably similar in their diets, reflecting the broad generalist diets of most predators (Fig. 1b). Although diet similarity appears to decline slightly with phylogenetic distance between predators, this effect disappears once we correct for non-independence of predator pairs with a Mantel test (correlation -0.27, p = 0.90, 999 permutations).
