Protonectarina sylveirae (Hymenoptera: Vespidae): first report preying Bedellia somnulentella (Lepidoptera: Bedelliidae) in Brazil

First record of Polybia scutellaris (White, 1841), (Hymenoptera: Vespidae) predating on Samea multiplicalis (Guenée, 1854) (Lepidoptera: Pyralidae), an herbivore of Salvinia spp. (Salviniaceae)

“…Nevertheless, P. scutellaris individuals were successful in locating and predating on larvae of Samea multiplicalis, penetrating into the leaves of Salvinia auriculata ramets. Similar foraging behavior was observed in other species of social wasps, which locate and predate their prey inside plant tissues (Bacci et al, 2019;Cabral et al, 2024).…”

Chartergellus communis (Hymenoptera: Vespidae): nesting and nest camouflage in different phytophysiognomies in the states of Bahia and Minas Gerais, Brazil

“…Social wasps play several ecological roles, such as predation, pollination, and are also bioindicators (Brock et al, 2021;Cabral et al, 2022). Information on the nesting of social wasps is extremely relevant, as it allows knowing the biology and nesting habits of these individuals, contributing to their preservation and the areas where they inhabit.…”

Polybia occidentalis (Hymenoptera: Vespidae) nesting on a Lafoensia glyptocarpa (Lythraceae) plant in the Cerrado biome

“…The ecological importance of P. occidentalis is high and therefore, the community structure (Cabral et al, 2024), prey and nectar stock (Karsai & Runciman, 2012), and plant associations (Cuautle & Rico-Gray, 2003) should be studied for this wasp. Studies on the preference of social wasps for plant substrate and the mechanisms for this choice in a semi-arid region is important for the conservation of these natural enemies (Souza et al, 2014).…”
