The European hornet Vespa crabro L. (Hymenoptera: Aculeata: Vespidae) is considered the largest native vespid wasp in Europe. The females use their sting to defend themselves and the colony. Despite a long history of research, the morphology of the sting in V. crabro remains insufficiently studied. Here, we provide a detailed description of the sting of V. crabro revealed with light microscopy, scanning electron microscopy and confocal laser scanning microscopy. Shape and sculpture of sting sclerites, sensilla of different morphotypes and peculiarities of the cuticle autofluorescence are combined to discuss the functional and phylogenetic significance of the sting characters in Aculeata.

“…The inner side of genal wall, jointly with the occipital and post occipital areas, form the attachment surfaces for the mandible musculature, principally the large adductor muscles (Duncan, 1939;Silveira & Santos, 2011). Additionally, in respect of the female mandible morphology, the species C. xanthura, C. fulvus, P. chartergoides, P. fuscatus, P. duckeianus, P. sedula, and several other of the P. exiguagroup studied by Silveira and Santos (2011) have very similar morphologies, with well-developed apical teeth, but considerably reduced mesial (inner) denticles. It therefore seems reasonable to speculate whether these particular morphologies (i.e.…”

Two more social wasp species (Vespidae, Polistinae) collect mullerian bodies from Cecropia trees (Urticaceae) IntroductionAssociations between plants and insects have long been known to science and may be among the oldest coevolved systems on our planet (Bronstein et al., 2006;Mishra et al., 2015). The evolution of both specific and generalist interactions has certainly facilitated great diversification among both plants and insects (Kasting & Catling, 2003). The Neotropical genus Cecropia Loefling (Cecropieae, Urticaceae) is commonly a participant in plant-insect mutualistic associations (Weiblen & Treiber 2015), with a large majority of its species (ca. 70) being myrmecophytic and developing specialized structures for sheltering ants (mostly the genus Azteca Roger; Dolichoderinae) (Treiber et al., 2016). Cecropia trees provide nesting domatia and food bodies (Mullerian bodies -MBds) produced by "trichilia" (sing. trichilium; pad-like organs located on the base of the leaf petiole) (Oliveira et al., 2015), and on the leaves (Gonçalves-Sousa & Paiva, 2016). In exchange, ants provide nutrients to the plants and help protect them against herbivory. AbstractThe interactive behaviors of two species of social wasps, Protopolybia chartergoides (Gribodo) and Charterginus fulvus Fox with Cecropia obtusifolia (Cecropiaceae) are described. The use of Cecropia Müllerian bodies by both wasps is also described, as well as the distribution of this trait in Protopolybia and Charterginus.

“…Against this broad social diversity, vespids show only modest physical diversity. In particular for our purposes, all studied species show a near uniformity in the gross structure of the venom apparatus, such that differences appear only in the relative sizes of some components [2,[32][33][34][35][36]. While solitary vespids appear usually to sting their prey into paralysis, present indications are that social species sting in defense of self or colony but seldom in subduing prey.…”

Comparative Morphology of the Stinger in Social Wasps (Hymenoptera: Vespidae)

The physical features of the stinger are compared in 51 species of vespid wasps: 4 eumenines and zethines, 2 stenogastrines, 16 independent-founding polistines, 13 swarm-founding New World polistines, and 16 vespines. The overall structure of the stinger is remarkably uniform within the family. Although the wasps show a broad range in body size and social habits, the central part of the venom-delivery apparatus—the sting shaft—varies only to a modest extent in length relative to overall body size. What variation there is shows no apparent correlation with social habits. This is consistent with the hypothesis that stinger size is constrained by the demands of a flight-worthy body. The sting lancets bear distinct, acute barbs in all examined species except in members of the Stenogastrinae. Barbs vary considerably among species in number, their summed lengths, and the relative degree of serration (summed length relative to lancet width). Where they are numerous and strong, it increases the likelihood of the stinger remaining fatally embedded in the skin of a vertebrate adversary (sting autotomy). Although an index that combines the number and strength of barbs is a more natural measure of overall serration, the number of barbs alone is almost as good a predictor of the likelihood of sting autotomy. Across the family as a whole, the tendency to sting autotomy is concentrated in the swarm-founding New World polistines.
