“…In the present study, the cetoniine beetles fed on sap not only from gall openings made by gallers but also from wounds inflicted by themselves. Such behavior has also been reported for another scarabaeid, Trypoxylus dichotomus L. (Coleoptera: Scarabaeidae: Dynastinae), which carves intact barks using the clypeus and sucks sap from the wounds (Hongo ). The finding that cetoniine beetles exhibited both active and passive use of gall sap was unique, and the relative importance of both behavior remains to be examined.…”

The alien moth Epiblema sugii (Lepidoptera: Tortricidae) induces stem galls on an invasive alien weed, Ambrosia trifida. During summer, along riverbanks in central Japan, the native insects Protaetia brevitarsis, P. orientalis submarumorea (Coleoptera: Scarabaeidae: Cetoniinae), and Camponotus vitiosus (Hymenoptera: Formicidae) feed on the sap exuded from the galls. The cetoniine beetles are highly aggregated among the galls and make wounds on the galls to facilitate sap exudation. Feeding on gall sap may be beneficial to the beetles due to the efficient intake of water and sugar, and the beetles' inflicting wounds and feeding on the sap seem to have little effect on the gallers. This is a unique finding, where alien plant-galler interaction provides a feeding site for native insects.

“…Adults preferentially feed upon pre-existing sap flows but may strip bark from trees to create temporary sap flows (Hongo, 2006) causing minor damage. Larvae of this species are not associated with living plants, instead feeding upon soil detritus .…”

“…Because the surfaces of F.griffithii trees are soft, adult T.dichotomus likely carve soft tree bark to obtain sap. In addition, previous real-time macroscopic video observations suggested that adult T.dichtomus carves bark using the projection of the clypeus, which is a chisel-like feature on the front of the head (Hongo 2006) (Fig. 1).…”

“…Adults of this species emerge in the summer and feed on the sap from tree wounds that are thought to be made by boring insects such as the larvae of cossid moths (Yoshimoto and Nishida 2007). Adult T.dichotomus feed extensively on sap and bark-carving behaviors have been observed on Fraxinusgriffithii trees (Hongo 2006), and these involved repeated head-scooping movements. Because the surfaces of F.griffithii trees are soft, adult T.dichotomus likely carve soft tree bark to obtain sap.…”

Adult horned beetles (Coleoptera, Scarabaeidae, Dynastinae) such as Trypoxylusdichotomus (Linnaeus, 1771) exhibit bark-carving behaviors to feed on tree sap, in part by using small projections of the clypeus. However, in the present experiments, adult horned beetles (T.dichotomus and Dynasteshercules (Linnaeus, 1758)) used their mandibles and not the projections of the clypeus to carve bark. Our findings show the presence of completely engaged mandibular interlocking, gear-like surface structures in molar areas that guide mandible opening and closure, and lead to completely synchronous movements of adult horned beetle mandibles. Three-dimensional shapes of these mandibular gear-like structures are complex and remained in contact after the death of a beetle. Moreover, adult horned beetles often performed bark-carving behaviors using only the mandible of one side, suggesting that the primary role of the mandibular gear-like structure is to prevent breakage of the mandible by transmitting load from one mandible to the other. Among the 22 Dynastinae and 16 other beetle species examined (not Dynastinae), the gear-like structure was found in all the Dynastinae species and in no other species.
