Atypically colored males (top left and bottom) and female (top right) of Rhynchophorus palmarum captured in pheromone-baited traps.
Percentages indicate the proportion of atypically colored weevils presenting off-color on the different body parts of the naturally all-black weevil. Overall, 152 off-colored specimens were caught in a total collection of 53,802 weevils.

Phylogenetic tree of the palm weevils (genus Rhynchophorus).
All published and our own sequences were included in the analysis. The African Rhynchophorus phoenicis does not appear in the cladogram as the sequences could not be aligned with those of other congeneric species and the similarity did not surpass 84% (reasons unknown).
