24 million years of pollination interaction between European linden flowers and bumble bees

open access: yesNew Phytologist, Volume 248, Issue 4, Page 2111-2127, November 2025.
Summary Pollination is the most common insect–plant mutualism, binding them in a co‐evolutionary framework. Historic evidence of this interaction can be partly inferred from time‐calibrated molecular phylogenies of plant and insect lineages or directly from fossils.

Body size and flight distance in stingless bees (Hymenoptera: Meliponini): inference of flight range and possible ecological implications Tamanho do corpo em Meliponini (Hymenoptera: Apidae): inferência do raio de vôo e possíveis implicações ecológicas

open access: yesBrazilian Journal of Biology, 2004
We examined the spatial implications of maximum flight distance for several species of stingless bees. Data suggested that maximum flight distance in Meliponini is a function of body size, especially generalized wing size, which can be estimated through ...

The Large Carpenter Bees (Xylocopa, Apidae) of the Neotropical Region: Phylogenetics, Classification and Biogeography

open access: yesZoologica Scripta, Volume 54, Issue 6, Page 884-896, November 2025.
ABSTRACT The large carpenter bees of the genus Xylocopa comprise almost 400 species distributed worldwide. Their large body and ability to build nests through woodworking make them one of the most remarkable groups of bees. In the Neotropics, they comprise over 100 species occurring in tropical and subtropical environments including islands in the ...

Recruitment communication in stingless bees (Hymenoptera, Apidae, Meliponini) [PDF]

open access: yesApidologie, 2004
The stingless bees (Hymenoptera, Apidae, Meliponini) have evolved sophisticated communication systems that allow foragers to recruit nestmates to good resources. Over the past 50 years, a growing body of research has shown that foragers can communicate three-dimensional resource location, uncovered several potential communication mechanisms, and ...

Evolution of Phospholipase A2 in Bees and Flies

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
This study investigated the evolution of the PLA2 gene in bees and flies and compared the evolutionary rate between them, which denotes the toxic group and the non‐toxic group. The results showed that PLA2 was under purifying selection and that an accelerated evolution of PLA2 occurred in the toxic group when compared with the non‐toxic group ...

The Life Histories of the "Uruçu Amarela" Males (Melipona flavolineata, Apidae, Meliponini)

open access: yesSociobiology, 2018
Here we describe the life histories of adult males of the the Amazonian stingless bee Melipona flavolineata Friese, commonly known as “uruçu amarela”. Males reach sexual maturity inside nests, presenting seminal vesicles full of sperm cells and becoming ...

An unusually large and persistent male swarm of the stingless bee Tetragonula laeviceps in Thailand (Hymenoptera: Apidae: Meliponini) [PDF]

open access: yes, 2014
At an entrance of a nest of Tetragonula laeviceps (Smith) located in Chiang Mai University campus we observed a male swarm that lasted for at least 40 consecutive days and contained more than 7000 males each time on several days. Surprisingly, harvesting
