New records and knowledge about the distribution of Eumeninae and Zethinae (Hymenoptera: Vespidae) in protected areas of the Atlantic Forest in southern Brazil [PDF]

Brazilian Journal of Biology
Eumeninae and Zethinae are currently treated as subfamilies within the Vespidae and, despite providing several ecosystem services, they are poorly sampled in Brazilian biomes, such as the Atlantic Forest.

Diversity and distribution of wasps and bees (Insecta: Hymenoptera: Vespidae, Apidae) in the Gauhati University Campus, Kamrup Metro, Assam, India

Journal of Threatened Taxa
The diversity and distribution of wasps and bees in the Gauhati University campus, Kamrup Metro, Assam was investigated in four different habitats: campus gardens, grasslands, residential areas, and areas adjacent to wetlands. Specimens were observed or

Ecology and evolution of pyrazines in insects

Biological Reviews, Volume 101, Issue 4, Page 1937-1959, August 2026.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

New host record for the enigmatic Neotropical mantidfly genus Anchieta Navás, 1909 (Neuroptera, Mantispidae), a mimic of wasps and stingless bees

Papéis Avulsos de Zoologia, 2021
Species of Symphrasinae (Neuroptera: Mantispidae) are ectoparasitoids of larvae and pupae of holometabolous insects, primarily of Hymenoptera in their larval stages.

Beyond the treeline: Are wood‐nesting bees and wasps limited by nesting habitat at high elevations?

Ecology, Volume 107, Issue 7, July 2026.
Abstract Although climate suitability is often thought to be the most important determinant of species ranges, non‐climate variables such as biotic interactions, dispersal abilities, and habitat quality may play equally important roles as range‐limiting factors.

The species of the genus Hypodynerus de Saussure (Hymenoptera, Vespidae, Eumeninae) occurring in Brazil

ZooKeys, 2013
An identification table and descriptions are given to recognize the two species of Hypodynerus (Hymenoptera: Vespidae: Eumeninae) recorded from Brazil: H. arechavaletae (Brèthes) and H. duckei (Bertoni) comb. n. The lectotype is designated and the

To provide pollinator nesting habitat, cut dead perennial stems in their first winter

Insect Conservation and Diversity, Volume 19, Issue 4, Page 933-944, July 2026.
Garden management practises need to consider stem‐nesting bees and wasps to avoid destroying active nests and important nesting materials. Volunteers collected samples of dead stems (in situ where they grew) in winter, spring, summer and fall as part of a participatory research project.

Parasitic behavior of Amobia distorta (Diptera: Miltogramminae) and defensive behavior of its hosts, Anterhynchium spp. (Hymenoptera: Vespidae: Eumeninae)

Entomological Science, Volume 29, Issue 2, June 2026.
The parasitic behaviour of Amobia distorta and the defensive behaviour of its hosts, Anterhynchium flavomarginatum (native species) and A. gibbifrons (probably non‐native), were observed. Abstract Two Anterhynchium species, A. flavomarginatum and A. gibbifrons, are solitary tube‐renting eumenine wasps that occur sympatrically in Japan.

Effects of flower patch additions and urbanisation on cavity‐nesting bees and wasps

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
Urbanisation can negatively affect cavity‐nesting bees and wasps, yet common conservation interventions such as flower patches and artificial nests lack strong empirical support. In a 2‐year experiment across urban allotments spanning an urbanisation gradient, we found no effect of added floral resources on nest uptake, while hymenopteran abundance ...
