The dorsal spines of immatures of some Aleurocanthus spp. are secretory. Sticky, viscous, retentive droplets are secreted through subapical orifices in the hollow spines of some species, through apical orifices in others. The droplets apparently allow the adherence of earlier nymphal exuviae, and may have a defensive function.
