Simple Summary: The scent system of Danaus is not only involved in sexual communication but also in mimicry. This study reports, for the first time, the morphological characteristics of Danaus' antennae and scent patches of the scent system for three species and explores their correlations. The ultrastructure of different antennal segments and their sensillum types was investigated, as well as the hierarchical structure of the scent patch, particularly the ultrastructure of its scales. Significant correlations were reported between the morphological characteristics of androconial scales in scent patches. Moreover, the antennal characteristics were significantly correlated. The morphological characteristics of the females' antennae were significantly correlated with those of the males' antennae and androconial scales. However, the significance and coefficient of these correlations were inconsistent across species and sexes. The study provides fundamental morphological information that may be involved in the pheromone recognition system of Danaus. The scent system of Danaus is important for the study of butterfly sexual communication and relevant investigations in biomimetics due to its involvement with mimicry. Using light, scanning, and transmission electron microscopy, the morphological characteristics of Danaus' antennae and scent patches of the scent system for three species, D. chrysippus, D. genutia, and D. plexippus, were investigated herein. Their apical clubs of the flagellums contain sensilla trichodea, sensilla chaetica, and sensilla coeloconica. The scent patch scales typically have a tree-like structure in its lumen at the nano-scale. Comparisons were made between the androconial scales and the other scales in scent patches. Rank sum tests showed significant differences in scent patch scales' characteristics between the species, as well as in the ultrastructure of antennal segments between species and sexes. Spearman's correlation tests showed significant correlations between the morphological characteristics of androconial scales in scent patches. Moreover, the antennal characteristics were significantly correlated. The morphological characteristics of the females' antennae were significantly correlated with those of the males' antennae and androconial scales. However, the significance and coefficient of these correlations were inconsistent across species and sexes. This study provides fundamental morphological information that helps in understanding the pheromone recognition system of Danaus. [ABSTRACT FROM AUTHOR] |
