Insect visitation patterns in diploid Centaurea aspera and its related allotetraploid and triploid hybrids: Similar rates but distinct assemblages

open access: yesAmerican Journal of Botany, Volume 112, Issue 9, September 2025.
Abstract Premise Polyploidy is key to plant evolution by contributing to speciation, diversification, and adaptability. However, the minority cytotype exclusion effect can limit the persistence of polyploids, which can be mitigated by reproductive barriers such as distinct insect visitation between cytotypes. In eastern Spain, the diploid C.

Seed Production and Pollinator Dependence in Native Wildflowers: Guiding Species Selection for Conservation Plantings

open access: yesEcology and Evolution, Volume 15, Issue 9, September 2025.
We investigated the pollination biology of eight native wildflower species in the southeastern U.S. to assess their dependence on insect pollinators and potential for self‐pollination. Most species showed significantly higher seed production and weight when open‐pollinated, indicating strong pollinator dependence, though some could reproduce without ...

New records of two Nyssonini (Bembicinae: Crabronidae) species from Korea, with a key to higher taxa of Sphecidae s. lat. occurring in Korea

open access: yesJournal of Asia-Pacific Biodiversity, 2015
Two Nyssonini (Bembicinae: Crabronidae: Apoidea) species, namely Nippononysson rufopictus and Nysson spinosus, are newly recorded in Korea. The genus Nippononysson is mentioned for the first time in Korean fauna.

The conservation value of Aculeata communities in sand quarries changes during ecological succession

open access: yesGlobal Ecology and Conservation, 2021
Sand quarries that are used occasionally and not subjected to rehabilitation are important biodiversity banks in both anthropogenic and semi-natural landscapes.

Phylogeny of "Sphecidae" (Hymenoptera: Apoidea) based on molecular data [PDF]

open access: yes, 2008
Die Grabwespen (Sphecidae sensu Bohart & Menke 1976; Sphecidae sensu lato in neueren, phylogenetischen Arbeiten), zu denen nach Day (1984) und späteren Autoren auch die Heterogynaidae zählen, umfassen derzeit 266 Gattungen mit 9559 beschriebene Arten ...

Spiders in a hostile world (Arachnoidea, Araneae) [PDF]

open access: yes, 2011
Spiders are powerful predators, but the threats confronting them are numerous. A survey is presented of the many different arthropods which waylay spiders in various ways. Some food-specialists among spiders feed exclusively on spiders.

Host identity, nest quality, and parasitism strategy: influences on body size variation in parasitoid bees and wasps

open access: yesOikos, Volume 2025, Issue 6, June 2025.
Body size determines mobility and fitness across taxa in various ways. Yet, drivers of body size in higher trophic invertebrates, especially parasitoids, including intra‐ and interspecific variations, are poorly understood due to complex interactions between parasitoid behaviour, the environment and their hosts.

Crabronidae Latreille 1802

open access: yes, 2007
Crabronidae Of this family 48 species from 23 genera were listed so far from these islands. The genus Solierella is represented by three species: S. canariensis, S. dispar and S. pectinata. Solierella dispar PULAWSKI 1964 is known from the island of Fuerteventura. On 11 May 2002 a female was caught on the island of Lanzarote, near San Bartholomé.

The clockwork of insect activity: Advancing ecological understanding through automation

open access: yesJournal of Animal Ecology, Volume 94, Issue 4, Page 597-610, April 2025.
The study demonstrates that time‐controlled insect sampling using an automated Malaise trap in combination with metabarcoding allows for the observation and documentation of taxon‐specific activity patterns. These recorded activity patterns can provide valuable insights into the underlying ecological processes, including parasitoid–host relationships ...
