Sex and Caste-Specific Variation in Compound Eye Morphology of Five Honeybee Species

Ranging from dwarfs to giants, the species of honeybees show remarkable differences in body size that have placed evolutionary constrains on the size of sensory organs and the brain. Colonies comprise three adult phenotypes, drones and two female castes, the reproductive queen and sterile workers. The phenotypes differ with respect to tasks and thus selection pressures which additionally constrain the shape of sensory systems. In a first step to explore the variability and interaction between species size-limitations and sex and caste-specific selection pressures in sensory and neural structures in honeybees, we compared eye size, ommatidia number and distribution of facet lens diameters in drones, queens and workers of five species (Apis andreniformis, A. florea, A. dorsata, A. mellifera, A. cerana). In these species, male and female eyes show a consistent sex-specific organization with respect to eye size and regional specialization of facet diameters. Drones possess distinctly enlarged eyes with large dorsal facets. Aside from these general patterns, we found signs of unique adaptations in eyes of A. florea and A. dorsata drones. In both species, drone eyes are disproportionately enlarged. In A. dorsata the increased eye size results from enlarged facets, a likely adaptation to crepuscular mating flights. In contrast, the relative enlargement of A. florea drone eyes results from an increase in ommatidia number, suggesting strong selection for high spatial resolution. Comparison of eye morphology and published mating flight times indicates a correlation between overall light sensitivity and species-specific mating flight times. The correlation suggests an important role of ambient light intensities in the regulation of species-specific mating flight times and the evolution of the visual system. Our study further deepens insights into visual adaptations within the genus Apis and opens up future perspectives for research to better understand the timing mechanisms and sensory physiology of mating related signals.

“…It has been shown for several sympatric species that the different daily mating flight times function as a mating barrier [8,12]. The period of drone flight activity has been observed in several locations (peninsular Malaysia, south-eastern Thailand [17], and Sabah, Malaysia [12]). At all locations recorded so far, all A. andreniformis drones fly around noon (when the sun passes its zenith), a time at which drones of other sympatric honeybee species stay in the nest.…”

-Mating flights of 3 virgin queens of Apis andreniformis were observed at their natural nesting site. They initiated mating flights between 12.33 and 12.50 h. The flight duration was between 19 and 23 minutes. The sting chamber of the returning queens contained the orange-colored secretion from the cornual gland of the drone's endophallus. Immediately after the mating flights, the queens were dissected. No sperm was detected in the oviducts, but spermatozoa were found in the spermathecae. In 2 queens, the spermathecae contained 0.09 million spermatozoa, which corresponds to about 75% of the sperm of 1 drone. The third queen had 0.31 million spermatozoa. The spermatozoa in the spermatheca were observed to be moving, and formed an undulating thread. These results suggest that sperm is transferred not into the oviducts but directly into the spermatheca (via the spermaduct). Seven egg-laying queens of unknown age had between 0.33 and 1.26 million spermatozoa in their spermathecae. The mode of sperm transfer is discussed in relation to the number and sequence of the spermatozoa received from each drone in the spermatheca.Apis andreniformis / queen / mating flight / sperm transfer/ spermatozoa count
