Heat drastically alters floral color and pigment composition without affecting flower conspicuousness

American Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise Floral pigments primarily serve to attract pollinators through color display and also contribute to protection against environmental stress. Although pigment composition can be plastically altered under stress, its impact on pollinator color perception remains poorly understood.

Geographic Range and Nest Architecture of Cephalotrigona Capitata Smith, 1854 (Apidae: Meliponini) in the State of Bahia, Northeastern Brazil

Journal of Apicultural Science, 2019
The bees of the genus Cephalotrigona (locally known as “mombucas”) play a key role in natural environments but their bioecological features, required to design proper management and conservation strategies, are scarce in most species.

Chemotaxonomical characterisation of males of Bombus lucorum (Hymenoptera: Apidae) collected in the Czech Republic

European Journal of Entomology, 2001
Labial gland secretions of 26 males of the bumblebee Bombus lucorum (L.), collected in the Czech Republic, were analysed. The secretions consisted of 60 compounds; ethyl (Z)-9-tetradecenoate was the main component (average 53%). Although the males varied

Stingless Bee (Apidae: Apinae: Meliponini) Ecology

Annual Review of Entomology, 2023
Stingless bees form perennial colonies of honey-making insects. The >600 species of stingless bees, mainly Neotropical, live throughout tropical latitudes. Foragers influence floral biology, plant reproduction, microbe dispersal, and diverse ecosystem functions.
