Colocasiomyia species and their occurrence frequencies in the inflorescences of Apoballis mutata. A. Colocasiomyia sp. 1 aff. bogneri. B. Colocasiomyia sp. 2 aff. bogneri. C. Colocasiomyia sp. 17 aff. bogneri. D. Colocasiomyia sp. 34 aff. bogneri. E. Number of Colocasiomyia flies and Cycreon beetles per A. mutata inflorescence categorized by anthesis phases (P: pistillate, S: staminate) and spathe colour (R: creamy melon-red, G: creamy green). F. Mean numbers (± SD) of individual Colocasiomyia species and Cycreon beetles recorded per inflorescence during pistillate and staminate anthesis. P values indicate the statistical significance of differences between spathe colour morphs for each insect taxon. G. Number of pistillate flowers per inflorescence and number of berries per infructescence of Apoballis mutata (N = 20). Scale bars: A–D = 1 mm. Photos A–D by Masonori J. Toda.
