Are Orchid Bees (Apidae: Euglossini) Good Indicators of the State of Conservation of Neotropical Forests?

Sociobiology, 2019
This work discusses the criteria proposed to consider wild bees as bioindicators and specifically applied to orchid bees in neotropical forests. Some of the issues are: 1) the deficiencies of the sampling methods, which makes it difficult to accurately ...

Radar tracking and motion-sensitive cameras on flowers reveal the development of pollinator multi-destination routes over large spatial scales [PDF]

, 2012
Central place foragers, such as pollinating bees, typically develop circuits (traplines) to visit multiple foraging sites in a manner that minimizes overall travel distance.

Suction feeding in orchid bees (Apidae: Euglossini) [PDF]

Proceedings of the Royal Society of London. Series B: Biological Sciences, 2004
Energy flux during nectar feeding is maximized at an intermediate sugar concentration, the value of which depends on the morphology of the feeding apparatus and the modality of fluid feeding. Biomechanical models predict that a shift from capillary-based lapping to suction feeding will lead to a decrease in this optimal sugar concentration.

The Orchid Bee Communities in different phytophysiognomies in the Atlantic Forest: from lowland to montane rainforests

Sociobiology, 2017
To investigate species composition, diversity, richness, and monthly abundance of orchid bees in different types of dense rainforest, placed in different altitudes, the orchid bees were collected for 11 months in three vegetation types: dense montane ...

Olfactory specialization for perfume collection in male orchid bees [PDF]

Journal of Experimental Biology, 2016
ABSTRACT Insects rely on the olfactory system to detect a vast diversity of airborne molecules in their environment. Highly sensitive olfactory tuning is expected to evolve when detection of a particular chemical with great precision is required in the context of foraging and/or finding mates.

Long‐term (1979–2019) dynamics of protected orchid bees in Panama

Conservation Science and Practice, 2021
Plants and pollinators are linked but their dynamics are scarcely known. Chemical monitoring of male “orchid bees” at two sites revealed 75% of species were stable or increasing.

A Quantitative Baseline of Ants and Orchid Bees in Human-Modified Amazonian Landscapes in Paragominas, PA, Brazil.

Sociobiology, 2016
The lack of effective biodiversity baselines is a major impairment to implement conservation plans. Hence, constructing and updating species lists provides vital information about species distribution records.
