Treating hummingbirds as feathered bees : a case of ethological cross-pollination [PDF]
, 2017 Hummingbirds feed from hundreds of flowers every day. The properties of these flowers provide these birds with a wealth of information about colour, space and time to guide how they forage.

Single locus complementary sex determination in Hymenoptera: an "unintelligent" design? [PDF]
, 2006 The haplodiploid sex determining mechanism in Hymenoptera (males are haploid, females are diploid) has played an important role in the evolution of this insect order.

Large-range movements of neotropical orchid bees observed via radio telemetry.
PLoS ONE, 2010 Neotropical orchid bees (Euglossini) are often cited as classic examples of trapline-foragers with potentially extensive foraging ranges. If long-distance movements are habitual, rare plants in widely scattered locations may benefit from euglossine ...

Orchid bee (Hymenoptera: Apidae) community from a gallery forest in the Brazilian Cerrado
Revista de Biología Tropical, 2012 The orchid bees are a very important group of pollinators distributed in the Neotropics. Although a lot of studies concerning male euglossine bees have been done in this region, few works have so far been carried out in the Cerrado biome. This manuscript

Floral Handedness in Mormodes Orchids: Revisiting Charles Darwin's Observations
Biotropica, Volume 57, Issue 6, November 2025.In this study, we scrutinized floral enantiostyly in Mormodes orchids, a unique trait within Orchidaceae first observed by Charles Darwin. We hypothesize how intricate column twisting drives strategic pollinarium placement onto opposite sides of the thorax of male euglossine bees, enhancing cross‐pollination.

Specificity Between Lactobacilli And Hymenopteran Hosts Is The Exception Rather Than The Rule [PDF]
, 2013 Lactobacilli (Lactobacillales: Lactobacillaceae) are well known for their roles in food fermentation, as probiotics, and in human health, but they can also be dominant members of the microbiota of some species of Hymenoptera (ants, bees, and wasps ...
