Rainfall shapes the physiological condition, but not the body size, of an introduced dung beetle in Brazilian pastures

open access: yesEcological Entomology, Volume 51, Issue 2, Page 346-355, April 2026.
Understanding rainfall‐driven physiological shifts in dung beetles is crucial to predict how climate change may affect the fitness and persistence of key insect species in tropical pastures. We compared body size, dry, lipid and muscle masses of Digitonthophagus gazella collected during dry and rainy seasons in Brazilian pastures to assess the effects ...

A study of the bionomy and description of the mature larva of Oxybelus trispinosus (Fabricius, 1787) (Hymenoptera: Crabronidae)

open access: yesThe European Zoological Journal
This paper provides comprehensive data on the life history of Oxybelus trispinosus (Fabricius, 1787). Female individuals of this species supply approximately 3–4 flies per cell as a food source for their larvae.

A Female‐Locust‐Inspired Hybrid Soft‐Stiff Robotic Digger: Mimetics and Implications for Digging Efficiency

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 3, March 2026.
Female desert locusts dig underground to lay their eggs. They displace soil, rather than removing it, to create a tunnel. We analyze burrowing dynamics and 3D kinematics and design a locust‐inspired hybrid soft–stiff robot that reproduces this mechanism. The results show the natural strategy minimizes energy, whereas alternative patterns raise costs up

Pyrodiversity of boreal lake islands begets biodiversity of beetles, plants, and birds

open access: yesEcological Applications, Volume 36, Issue 2, March 2026.
Abstract Global fire regimes are changing, raising concerns about the ability of fire‐prone ecosystems to maintain biodiversity. We tested whether the pyrodiversity–biodiversity hypothesis (i.e., variation in postfire characteristics promotes biodiversity) or alternative hypotheses better explain patterns of biodiversity in a true island system.

Notes on the Nests of \u3ci\u3eAugochloropsis metallica fulgida\u3c/i\u3e and \u3ci\u3eMegachile mucida\u3c/i\u3e in Central Michigan (Hymenoptera: Halictidae, Megachilidae) [PDF]

open access: yes, 2017
Notes on the nesting biology of two ground-nesting species are provided from Central Michigan. A single nest of Augochloropsis metallica fulgida was excavated on 12 July 2014 in Shiawassee County. There were two female nest inhabitants.

Nesting of Oxybelus quatuordecimnotatus Jurine, 1807 (Hymenoptera: Crabronidae) from Poland

open access: yesThe European Zoological Journal
Nests of Oxybelus quatuordecimnotatus Jurine, 1807 were examined in the village of Sierakowo in northern Poland. Adult insects were encountered from early June to mid-August. Eight nests were observed; three were excavated and examined.

Sexual selection and the evolution of male pheromone glands in philanthine wasps (Hymenoptera, Crabronidae)

open access: yesBMC Evolutionary Biology, 2017
Background Sexual selection is thought to promote evolutionary changes and diversification. However, the impact of sexual selection in relation to other selective forces is difficult to evaluate.

Oocyte size, egg index, and body lipid content in relation to body size in the solitary bee Megachile rotundata [PDF]

open access: yes, 2014
Females of solitary, nest-provisioning bees have relatively low fecundity, but produce large eggs as part of their overall strategy of investing substantially in each offspring.
