“…The gross morphology of mouthparts of D. damnosa are similar to some other described auchenorrhynchans (Cobben, 1978;Dai et al, 2014;Leopold et al, 2003;Mora et al, 2001;Tavella and Arzone, 1993;Wang et al, 2015;Wiesenborn, 2004;Zhao et al, 2010).…”

“…For example, leafhoppers, psyllids and aphids have relatively more teeth (Forbes, 1969;Garzo et al, 2012;Leopold et al, 2003;Liang et al, 2013;Tavella and Arzone, 1993;Ullman and McLean, 1986;Zhao et al, 2010), whereas there are only 5 teeth on the mandibular stylet in spittlebugs and delphacids (Dai et al, 2014;Mora et al, 2001;Wang et al, 2015). D. damnosa have 7 relatively unapparent protuberances on their mandibular stylets which is different from other auchenorrhynchans.…”

“…However, limited anatomical studies of mouthparts structures and sensilla have interfered with understanding of sensory mechanisms and mediation of feeding in the Auchenorrhyncha. In Fulgoromorpha, research on mouthparts has focused on labial sensilla (Backus, 1985;Brożek and Bourgoin, 2013a;Foster et al, 1983b;Liang, 2005;Mora et al, 2001;Sōgawa, 1977;Wang et al, 2012), the interlocking mechanism of maxillae and mandibles (Brożek et al, 2006;Brożek and Bourgoin, 2013b), or description of mouthpart morphology just for delphacids (Dai et al, 2014;Mora et al, 2001).…”

When attacked or otherwise disturbed, larvae of the aquatic firefly Luciola leii display fork-shaped glands laterally from the meso-and metathorax as well as each abdominal segment. Glandular eversion is accompanied by a strong pine oil-like odour, thanatosis and glowing from paired larval light organs. Observations by SEM and TEM revealed that there are numerous, almost spherical protuberances, measuring 9 µm in diameter on the surface of each gland. Each protuberance is connected to a well developed secretory cell via a 0.1 µm thick and 0.2 µm long stalk and bears three to six 7 µm long spines on its apex. The convoluted glandular walls measure 0.2 µm. The cytoplasm of the secretory cells is characterized by the presence of numerous mitochondria and an extensive system of cisternae and tubular endoplasmic reticulum. Preliminary GC-MS analysis of the glandular secretion revealed two volatile terpenoids: terpinolene and γ-terpinene. Choice and no-choice bioassays involving fish and ants as well as other predators demonstrate that the secretions serve as an effective deterrent against a range of ecologically relevant enemies. The larval postural adjustments, light emission, everted glands, and glandular release of distasteful or repellent compounds, appear to function as a multi-modal, aposematic larval defence. The tandem evolution of glandular secretions and conspicuousness in larval fireflies could partially explain their successful radiation into both aquatic and terrestrial habitats.

Larval defensive behaviour and eversible organ morphology were compared in the firefly species Luciola cruciata Motschulsky 1854, L. lateralis Motschulsky 1860, L. leii Fu et Ballantyne 2006, Lampyris noctiluca Linnaeus 1767, Pyrocoelia analis Fabricius 1801, P. pectoralisOliver 1883, P. sp. and two Diaphanes species. In all cases the eversible organs are located on the pleural cuticle, dorsal to the spiracle, but there is considerable variation between species in their number, size and shape. In La. noctiluca they are confined to the abdomen, whereas in the other species they also occur on the meta-and mesothorax. In La. noctiluca and the Pyrocoelia species the organs are columnar in shape, contrasting with the forked organs of the Luciola and Diaphanes species. The eversible organs of the Luciola species, which are all aquatic, are remarkably larger (relative to body length) than those of the other, terrestrial species. On organ eversion the Luciola species emit an odour resembling pine oil, the Diaphanes species smell weakly of mint and L. noctiluca and the Pyrocoelia species produce no discernible scent, though ants are nonetheless repelled by contact with everted L. noctiluca organs. The organs of all the species studied support protuberances on their external surface, though these too vary in shape, size and ornamentation between species. In all species except L. noctiluca each protuberance is connected to a well-developed globular body via a long, thick stalk. Circular foveae are located in the centres of these globular bodies. The globular bodies consist of secretory cells characterized by the presence of numerous mitochondria and an extensive system of cisternae and tubular endoplasmic reticulum. Behavioural tests revealed that small larvae run away instead of becoming immobile and glowing, whereas large larvae start to glow when disturbed. The study shows that the eversible larval organs form an important part of a defensive arsenal in the Lampyridae.
