Macronutrient composition in pollen affects development and survival in wild bees

Physiological Entomology, Volume 51, Issue 2, Page 350-362, June 2026.
Small carpenter bees (Ceratina calcarata) were reared on diets formulated with black poplar and dandelion pollen, while closely monitoring developmental metrics, lipid content and survival. Macronutrient analyses on both pollen types revealed dandelion pollen contained lower levels of protein, essential amino acids and several fatty acids, which ...

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

Zoologica Scripta
ABSTRACTThe 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 ...

First record ofHuarpea wagneriella(Hymenoptera: Sapygidae) as a cleptoparasite of large carpenter bees (Hymenoptera: Apidae, Xylocopinae)

Studies on Neotropical Fauna and Environment, 2016
ABSTRACTThe species Huarpea wagneriella (Hymenoptera: Sapygidae), a cleptoparasite of nests of bees of the genera Xylocopa Latreille and Megachile Latreille (Hymenoptera: Apoidea), is reported for the first time as a cleptoparasite of Xylocopa ciliata Burmeister (Hymenoptera: Apidae) in Buenos Aires, Argentina.

Estimating body size in the large carpenter bees (<i>Xylocopa</i>)

Journal of Melittology
Body size is a salient functional trait in bees, with implications for reproductive fitness, pollination ecology, and responses to environmental change. Methods for quantifying bee body size commonly rely on indirect estimates and vary widely across studies, particularly in studies of the large carpenter bees (Xylocopa Latreille) (Apidae: Xylocopinini).

The large carpenter bees (Hymenoptera: Apidae: Xylocopa spp.) of Nuevo León, México

Journal of Pollination Ecology, 2012
There is a severe information gap regarding wild bees in northern Mexico. The present study is a contribution to knowledge of the distribution, habitat preferences and floral usage patterns of bees of the genus Xylocopa in the state of Nuevo León.

Foraging strategies and physiological adaptations in large carpenter bees

Journal of Comparative Physiology A, 2019
Large carpenter bees are charismatic and ubiquitous flower visitors in the tropics and sub-tropics. Unlike honeybees and bumblebees that have been popular subjects of extensive studies on their neuroethology, behaviour and ecology, carpenter bees have received little attention. This review integrates what is known about their foraging behaviour as well

Presence of a thermoregulatory hot spot in the prothorax of the large carpenter bee and the bumble bee

Microscopy Research and Technique, 2006
AbstractIn both the large carpenter bee (Xylocopa pubescens) and the bumblebee (Bombus terrestris), a hot spot was detected in the center of the prothorax on its dorsal‐external aspect. In both cases, the temperature in this hot spot was found to be greater than the ambient temperature and that at the tip of the gaster. In B.

Big in the tropics–Are there thermal advantages of large body size for carpenter bees in hot climates?

Ecological Entomology, 2023
Abstract Large body size is a major advantage for flying insects living in cold climates. Size‐related metabolic heat production allows them to maintain their body temperature high enough for flight even at low ambient temperatures.

Factors Affecting the Nesting Success of the Large Carpenter Bee, Xylocopa californica arizonensis

Environmental Entomology, 1978
The nesting success of Xylocopa californica arizonensis Cresson (Hymenoptera:Anthophoridae) is determined primarily by the availability of pollen and nectar and by the presence of a source of nest substrate. X. c. arizonensis appears to depend upon the pollen of Larrea tridentata or Prosopis spp. for larval food, when it is available.
