ABSTRACT: The marine water-strider Halobates hayanus is prevalent in tropical and subtropical marine habitats.
Although the ecology and the morphology of this insect are widely accepted, some histological data remain limited.
In this study, we determined new data on the organ histological development for specific performance of H. hayanus,
locally collected with respect to its total length (TL) from Libong Island, Thailand. Our observation revealed that the
TL of this insect could be divided into three groups: (1) Small, 0.1?0.2 cm; (2) Medium, 0.3?0.4 cm; and (3) Large,
0.5?0.6 cm. Histologically, subsequent microscopic development of eyes, Malphigian tubules, midgut, and gonads
of H. hayanus were found in Group (3), 0.5?0.6 cm in TL. Surprisingly, the distinctive structure of pigment cells,
with strong pigment granules and crystalline cones, was also found in the 0.5?0.6 cm group. Clear mature testes
with the presence of sperms were evident in the 0.1?0.2 cm group, and the sampled females from the 0.5?0.6 cm
group had mature ovaries with the presence of the vitellogenic stage. The results obtained from this study expanded
the histological data of H. hayanus from natural environments, contributing to further determination of the insect?s
development stages and physiology
