The Malaise Trap: Its Utility and Potential for Sampling Insect Populations [PDF]

open access: yes, 2017
Slightly over three decades have elapsed since Malaise (1937) first published plans for the insect trap now bearing his name a stationary mesh tent with open sides, a central baffle, and a top-mounted collecting apparatus (Fig. 1).

The Mesosoma of Protanilla (Leptanillinae) and the Groundplan of the Formicidae (Hymenoptera)

open access: yesJournal of Morphology, Volume 286, Issue 7, July 2025.
Phenomic investigation of the mesosoma of Protanilla lini reveals groundplan features of the ants and raises new homology questions for future investigation, both within Formicidae and across Aculeata. Special highlights include refined definition of the pronotum, complex discoveries of the promesothoracic articulation, and a new perspective on and ...

Climate explains global functional trait variation in bees

open access: yesFunctional Ecology, Volume 39, Issue 7, Page 1748-1760, July 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate is a fundamental driver of macroecological patterns in functional trait variation. However, many of the traits that have outsized effects on thermal performance are complex, multi‐dimensional, and challenging to quantify at scale.

Sex-biased parental care and sexual size dimorphism in a provisioning arthropod [PDF]

open access: yes, 2015
The diverse selection pressures driving the evolution of sexual size dimorphism (SSD) have long been debated. While the balance between fecundity selection and sexual selection has received much attention, explanations based on sex-specific ecology have ...

A systematic review and meta‐analysis on urban arthropod diversity

open access: yesInsect Conservation and Diversity, Volume 18, Issue 4, Page 447-464, July 2025.
Our results evidence that urbanization is associated with a lower mean diversity of arthropods. We also detected a higher variance of arthropod diversity in urban than in rural habitats. Reported data suggest that cities hold a great potential for arthropod conservation if adequate measures are implemented. Abstract Urbanization is rapidly expanding at

Colletidae nesting biology (Hymenoptera: Apoidea) [PDF]

open access: yesApidologie, 2008
Colletidae are unique among bees for certain aspects of their nesting biology. In this review, attributes of colletid nesting are evaluated and discussed in light of a novel phylogenetic hypothesis for the family. Some predictions made about evolution of certain traits, such as the cocoon-spinning behavior of Diphaglossinae, are confronted with ...
